About Chip McCormick Custom, LLC™
  Innovation in ammunition design has improved the performance of the 9mm cartridge when compared to older, full-metal jacket rounds. The popularity of chambering the 1911 for the 9mm cartridge has produced a pistol that is easier to shoot because of lower felt recoil. The result of lower felt recoil has the added benefit of improving marksmanship for many shooters. Another benefit of chambering the classic 1911 in 9mm is the increase of capacity in the standard flush fitting magazine tube. The cost of 9mm ammunition is also less expensive than .45 ACP.

These new technological developments are resulting in a reframing of the old 9mm vs .45 ACP debate. Nowhere is this new wave of enthusiasm for the 9mm cartridge more evident than in law enforcement, where elite Federal agencies like the Federal Bureau of Investigation are transitioning to the 9mm cartridge.

On the civilian side of the debate, most of the renowned manufacturers of the classic 1911, such as Springfield Armory, are now chambering models in the 9mm cartridge.

The issue of the difference in cartridge length between the 9mm round and the .45 ACP round has always been problematical in getting the 9mm round to feed reliably out of the 1911 magazine as the design and dimensions were originally dedicated to the .45ACP cartridge. From the “Mind of McCormick™” came the answer.

The 9mm cartridge uses a tapered case and the standard 1911 9mm magazine design forces the round to the front of the magazine tube. This is even more so with any extra capacity ten-round magazines. The solution offered by Colt in the original 9mm magazines and in virtually every other manufacturer’s 9mm magazines has always been to have a spacer welded into the rear of the tube to push the shorter 9mm round to the front of the magazine tube.

One of the issues in spacing the rounds forward is that Chip feels it excessively changes the original feeding dynamics of the 1911 pistol as was intended by the pistol’s designer, John Moses Browning. In magazines that space the cartridge at the front of the magazine tube this is readily evident. When the slide moves forward during feeding, the breach face engages the base of the 9mm cartridge appreciably farther forward than where it does with the .45 ACP cartridge. 

Spacing the rounds farther forward also causes each round to go through a significantly greater cycle of angular changes during the transition of the rounds from magazine to barrel chamber.

Another major concern is under extreme usage, the strength of the feed lips is compromised by moving the round forward and away from the back corner of the feed lips. The rear of the feed lips at the back corners of the magazine is their strongest area. When loaded to capacity, the upward movement of the 9mm rounds has significantly more leverage on the forward area of the feed lips. This can result in spreading the feed lips on the conventional 9mm magazine. It is especially true with hard usage. The repeated slamming of the magazine into the pistol at slide lock during speed reloads significantly reduces the service life of the magazine.

Chip’s approach in designing a new 9mm magazine for the 1911 was to stay true to the original feeding dynamics of the pistol. Chip’s design for an extra capacity 1911 10-round, 9mm magazine was to eliminate the rear spacer in the magazine tube. By shimming each of the 9mm rounds all the way to the rear of the .45 ACP length tube, it places the upward leverage of the rounds on the strongest section of the feed lips.

This innovative new design concept afforded him a significant opportunity to use the remaining space for the incorporation of a large and extremely effective integral feed ramp in the front of the 9mm tube. This unique integral feed ramp provides CMC’s new XP 10-round, 9mm magazine remarkable feeding reliability for all ten rounds in the magazine.

The extra capacity of the tenth round (the original Colt magazine only held nine rounds) is due to the unique steel CMC follower design that is the legacy of the first patent that Chip owned. But never settling on past technology, the unique new follower was designed specifically for the new XP ten-round, 9mm magazine tube with the innovative integral feed ramp.

The combination of a dedicated 9mm magazine follower and a novel integral feed ramp means the tips of the 9mm projectile can no longer engage down low on the pistol feed ramp like other 1911 9mm magazines. Instead, the tip of the bullet engages the integral feed ramp in the magazine in such a way that the round is directed straight up and into the chamber of the barrel.

Chip says, “I have tested the new XP ten-round, 9mm magazines with a variety of bullet types in different 1911 9mm pistols, from budget foreign-made copies to the most expensive examples of the custom gunsmiths’ art. In all the cases I have tested of the pistol and ammo combinations, my new XP ten-round, 9mm magazine are clearly the most reliable.”

Chip’s wide range of clients in law enforcement and the military made him aware of the problem of getting a consistent trigger pull with minimum take-up and over-travel on the M16/AR-15 rifle. Once again the Mind of McCormick™ would come up with the solution. This time, Chip’s research and designs would result in three patents being issued to him by the U.S. Patent and Trademark Office related to a drop-in AR-15 trigger group.

This remarkable trigger group for the AR-15 allowed gunsmiths to install it in a rifle in minutes. Once it was installed, the gunsmith only had to check for safe and proper function. There were no screws to adjust or worry about coming loose. 

In the manufacture of the trigger group, as with all of CMC’s products, there were no compromises in its quality. Tolerances of +/- .001 were standard for all engagement surfaces. Hammer, trigger, disconnector and pins were made of the highest grade, hardest, longest wearing materials available. The assembly was contained in a high grade 410 stainless steel housing. It used full strength music wire springs for fast lock-time and reliable discharge with factory or military ammunition.

The Super Match Trigger Groups for the AR-15 were so popular that it was hard keeping up with the demand. Customer satisfaction has always been one of Chip’s top concerns. In 2011, he decided to take the offer from a group that would make the production of the CMC Triggers their main objective and fill the supply lines so every AR-15 shooter would not have to wait to get the ultimate trigger in their rifle.

In 1994, Chip was contacted by agents of Kimber™ about purchasing our 1911 trigger group components of that era and extra capacity 8rd magazines for use in Kimber's proposed new line of pistols. And they wanted Chip McCormick, personally, to endorse the new line.

As a consultant, Chip was reluctant to endorse another run of the mill 1911 pistol and instead recommended that Kimber consider Chip’s fresh approach to developing a significantly advanced grade of production 1911-style pistols. Instead of simply copying existing models he suggested that they take a whole new approach to production of 1911 pistols. From his experience working with aerospace companies, Chip believed that by following aerospace protocols in manufacturing it would allow for closer tolerances increasing the accuracy and reliability of the new production pistols. As part of creating a whole new data package for 1911-style pistols he could also incorporate all of the popular features found on full-house custom 1911 pistols such; as extended ambidextrous thumb safety, high ride beavertail grip safety, high visibility sights with rounded edges, rounded corners on slides, front grip checkering, adjustable triggers, extended mag catches, beveled magazine wells, front and back slide serrations. This new line of custom 1911-style pistols would now be available to shooters at production prices. 

Chip's recommendations were agreed to and his company was contracted to do all the design work for the new line of parts for Kimber. They supplied Kimber with a new Technical Data Package for every single component except springs and pins. Chip endorsed the new line of Kimber™ 1911 pistols. Shortly after their introduction, Kimber’s new pistols became known as the finest factory 1911 pistols ever produced. The new innovative line of Kimber pistols raised the bar for all 1911 manufacturers. Today, you can find production 1911 models from them with similar enhancements that Chip pioneered with Kimber.  

The year 1991 was momentous in the designs coming from the Mind of McCormick™. Early that year, Chip invented and patented a unique and novel trigger guard locking device for holsters. He sold the rights to that design to Safariland, and for years it was the dominant holster in action shooting competition. Applications of the design were also incorporated into duty and carry holster models.

Also that year, Chip McCormick Corp. introduced the “McCormick Modular Hi-Capacity 1911 frame. Jerry Barnhart won the 1992 USPSA National Championship using a McCormick Modular frame for his pistol built by Wilson’s Gun Shop. This frame later became known as the STI 2011 and SVI frame. It is still dominant in IPSC/USPSA-style sports that require high-capacity pistols in order to be competitive. 

However, America’s most elite law enforcement and military units had determined that, in the real world of self-defense and combat, high-performance pistols based on the original 1911 design were the most effective Close Quarters Battle (CQB) weapons. CMC discontinued the high-capacity concept in order to focus 100% on maximizing the performance of the tried-and-true 1911-style pistol.

​    In the last 30 years, tens of millions of rounds have gone through CMC Mags, from the dusty ranges of the World Speed Shooting Championships in California to the battle fields of Afghanistan and Iraq. Early in his professional shooting career, Chip McCormick discovered an important fact: that he needed to keep his 1911 pistols running under the stress of world class international competition.

Chip began competing in Practical Shooting matches in 1981. He soon discovered that with all the money he spent on having his pistols custom tuned by leading pistolsmiths of the day there was one thing he could not solve. No matter how much time and effort went into blueprinting and customizing his pistols for competition there was one thing that he could not control.

The Achilles Heel of the autoloading pistol is the magazine that feeds the rounds into the barrel’s chamber. He was constantly sorting through cheaply made magazines trying to find the best ones to use on match day. There was nothing more frustrating than to spend months training for a world championship and to be knocked out of the running due to a magazine failure.

He was outraged that his precision pistol could be turned into a boat anchor by cheap, factory junk magazines. The professional shooter made it his never ending endeavor to see that his fellow shooters would always have a far superior choice of magazines than the inferior hunks of sheet metal that were available to him.

Early on Chip started researching, learning about the applicable manufacturing processes and determining his objectives for the new 1911 magazines he wanted to produce some day. The cauldron of action shooting competition provided the ideal testing ground for his pro-type magazines. Shortly after winning his first World Speed Shooting Championship title in 1986, Chip knew that his designs could benefit others. He decided to give the edge he enjoyed with his equipment and entered another competitive arena: the manufacturing of performance products for 1911 type pistols. “It is debatable as to which form of competition is tougher, pistol matches or the firearms industry,” said the Steel Challenge Champion.

When Chip made the decision to manufacture products that would give 1911 shooters a competitive edge, there were three criteria. They had to be innovative. They had to be made to his standard of excellence. And they had to be 100% made in America.
And every customer would be guaranteed quality and satisfaction with every magazine purchased directly from CMC Mags or their participating dealers having a 30-day satisfaction guarantee. And Chip has always stood by his products covering any failures due to materials or manufacturing defects.

For over 30 years, Chip McCormick and his team have been delivering quality that gives you that winning advantage. Below is the saga of the continuing effort at CMC Mags to provide you with the best equipment, so you can shoot your best on the range or in the field.
Changing The Game For Over 30 Years!
10rd XP 9mm Mag
10rd Power Mag+
  In 1949, the U.S. Military was looking for a lighter weight pistol than the standard issue 1911 for officers to carry in 9mm. Colt submitted a modified version of the 1911 with a shortened slide and barrel on an aluminum alloy frame. In 1950, Colt put their candidate into regular production. The Colt Commander had a 4.25-inch barrel, weighed 27 ounces with its alloy frame. It was the first pistol that Colt chambered in 9mm and it had a 9-round magazine. The Colt Commander was also chambered in .38 Super and .45 ACP.

For those people in law enforcement who carried a pistol on long shifts, the light-weight Commander was an instant hit. The Commander started a trend among 1911 fans who wanted their favorite pistol in compact and lightweight versions.

The price of a lightweight 1911 on the belt was a reduction of service life, especially in .45 ACP. While the aluminum frame is lighter weight, the metal alloy is not as durable as steel.

Yet for both law enforcement and civilians with concealed carry permits, the issue of weight on the belt is a major issue often outweighing durability. But steel frame or aluminum alloy frame, the pistol had to function reliably. They needed the best magazines they could get for them.

In designing magazines, Chip’s preference is for steel followers in his state-of-the-art magazine tubes. The CMC Mags’ unique follower designs require only a bare minimum of bearing surface contact to the inner walls of magazine tubes. Less bearing surface yields greater margins for continued reliable function when used in gritty or grimy environments. In the field when cleaning and maintenance is not practical, the added benefit of CMC’s unique steel follower design can be lifesaving.

Over the years, our many federal law enforcement and military special ops customers have told us that they are not only concerned with feeding, but also with reliable slide lock upon last shot fired (notifying weapon empty). This last issue is extremely important in the haze of battle.

All of CMC’s unique follower designs are such that the followers themselves are also springs, yielding additional strength to that of the common coil type spring that all 1911 magazines incorporate. CMC’s follower designs allow for each of the “Rocket” wire spring coils to be wider and longer in coil design throughout the length of the spring, yielding superior spring strength by design as compared to any other brand of extra capacity 1911 magazines. The combination of CMC’s follower (a spring itself) and larger spring coil designs yields more strength in any given length of magazine tube.

This springing effect means that the Power Mag follower jumps forward after the last round has been fired, yielding increased engagement of the follower to the internal lobe of the slide stop. It gives the most positive slide stop engagement possible for activating the slide stop to lock the slide open. When this happens, it is possible for the metal follower to make contact with the frame. There are no issues of steel contacting steel with a steel frame. 

But with an aluminum alloy frame the steel follower can, in some instances, come in contact with the softer metal of the receiver. This is only a concern for those who choose to release the slide forward when the empty magazine is seated in the pistol. And this is not an issue at all, if the empty magazine is removed from the pistol at slide lock and then the slide is released forward.

Not wanting to give up the benefits of a steel follower, Chip came up with the answer: the Power+ follower. The Power+ follower accomplishes the same tasks as the Power Magazine follower but in a different way. The Power+ follower is more stable and remains within the confines of the magazine tube.

Since the follower in the Power+ Series of magazines cannot come in contact with the receiver, the Power+ magazines are recommended for those owners of 1911 pistols with aluminum alloy receivers. They come in our standard length eight-round extra capacity magazine as well as our extended length ten-round magazine.

Of course, as the long history of CMC Mags has proven, no other magazine has the combination of quality, reliability, service life and customer satisfaction of CMC’s Power™ series magazines. With the introduction of the Power+ magazines, you now have the reliability of a steel follower in the world’s best magazine for your lightweight aluminum alloy framed Commander and other compact 1911-style pistols. 

Never satisfied with the status quo, the Mind of McCormick™ searched for the next evolution in 1911 magazine design. In 1999, Chip introduced the extra heavy duty Power Mags™. They were designed to increase reliability and service life, in all environments, even when kept fully loaded and seated in a pistol for extended periods of time. 

The stainless steel tubes are produced on CMC’s own proprietary tooling that is die-controlled to tolerances that are at least half of the original military tolerance specifications for the 1911 pistol magazine. 

The extra power comes from 11 coils (three more than in a Match Grade) in the spring of aerospace grade Rocket Wire. It is called Rocket Wire because it was developed by NASA as part of the Space Shuttle program.
The huge increase in spring power created by the extra coils of aerospace grade wire pushes upward on each cartridge as it feeds through the Power Mag tube. This will improve the reliability of any 1911-type pistol. It also significantly increases service life, offering maximum resistance against wear and fatigue. This is especially true when the magazines are used constantly or loaded and seated in the pistol for extended periods of time.
The integral base plate/pad is completely removable for convenient cleaning and maintenance. Their design provides full-length engagement from front to back, between the magazine tube retaining lips and base pad grooves to ensure maximum strength and reliability.

The ten-round Power Mag is designed to incorporate an additional three coils of Rocket Wire spring. The integral base plate has an integrally molded shroud that gives the elegant appearance of a standard magazine with an extended base pad attached. It eliminates the exposure of any sharp metal edges on the bottom of the magazine tube. The shroud is tapered at the top for positive locking, even if there is an extended magazine well added to the bottom of the 1911 pistol.

Since 1999, the Power Mags continue to outsell competing magazines. After extensive testing by Federal law enforcement, Power Mags are used by their elite groups. From the beginning of the conflict in Afghanistan and the conflict in Iraq, military Special Ops and RECON units have purchased and used Power Mags. Throughout the numerous years of those conflicts there were no reports of; failures due to spring fatigue, failures due to cracked feed lips, failures due to follower wear, or failures due to broken bases. CMC’s Power Mags give you the edge when you need it.

10rd Power Mag
Being competitive at the top of any sport requires disciplined training and a dedication of resources. To be a world class athlete requires enormous amounts of time and money. In the action pistol sports, competing against champions like Rob Leatham and Jerry Barnhart also required focus. There just wasn't enough time in a day to be the best at both shooting and making firearms parts. So, in 1990, Chip retired from professional shooting to concentrate on designing and manufacturing extraordinary 1911 products.

His first passion was the 1911 magazine, because for a semi-automatic pistol to be reliable it needs the finest feeding mechanism possible. Chip sought out and employed the services of one of America’s top aerospace and defense industry manufacturers. He would use state of the art technology to advance his designs that far exceeded the capabilities of existing firearms manufacturers.

The first task was to re-engineer the specifications of the original Government Issue 1911 magazine and reduce all functional tolerances by half. Tightening up the tolerances made it possible to optimize the nominal dimensions for enhanced function and reliability. 
Once the sheet metal is blanked out and substantially formed into the shape of a magazine tube, it needs to be welded to complete the forming of a closed tube. Conventional welding of the tube leaves irregular weld puddles along the back of the magazine. In order to render the back of the magazine tube flat, the traditional method is to sand or grind the back flat. The problem with sanding or grinding on the back side of the tube is that it will thin and weaken the rear of the feed lips. This weakened area is what produces cracked feed lips in the many 1911 magazines that are still produced using antiquated methods. 

Chip, using aerospace technology and production methods, invested the capital to have the rear of his tubes welded by laser. Laser welding creates a seamless line down the back of the magazine tube. To ensure maximum benefit and consistency in the laser welding process, the additional investment was made to build a self-contained laser welding room that is both atmospherically and temperature controlled. 
CMC mags were the first 1911 magazines to incorporate laser welding. Since Chip’s introduction of laser welded magazine tubes in 1990, there has never been report of a single crack in the rear feed lips of any CMC magazines.

Shooting Star Classic
8rd .45ACP

Chip won the second World Speed Shooting Championship title in 1988. And it was the year Chip McCormick Corp. revolutionized trigger parts for the 1911. Previously, the only way a shooter could obtain a "match grade" trigger job was to send his pistol away to a custom gunsmith to handwork the components. This usually meant a very long waiting period that left the shooter without the pistol for month at a time. Since about only four or five of the very best gunsmiths could make a dependable match-grade trigger job, most shooters soon discovered that their long-awaited, and expensive, trigger jobs by most gunsmiths were not reliable. Chip McCormick Corp. was the first to offer the readily available precision components required for obtaining a perfect trigger pull with a long lasting service life. When Chip introduced his advanced trigger components he paved the way for the technology and the parts in production 1911 pistols that now have a crisp, reliable trigger pull out-of-the-box.

 Shortly after winning his first World Speed Shooting Championship title in 1986, Chip entered the enormously competitive area of manufacturing performance products for 1911 type pistols. It is debatable as to which form of competition is tougher, pistol matches or the firearms market place.

In 1986, he began manufacturing the Shooting Star™ line of extra-capacity magazines for 1911-type pistols. The introduction of the eight-round .45 ACP and ten-round .38 Super magazines were the first major advancement in over seven decades for 1911 pistol magazines. 

There was no magic in getting extra capacity out of the original seven-round magazine that John M. Browning had designed for Colt Firearms in 1911. It was brilliant engineering that produced the patented follower that became known as the “Shooting Star” follower and made it possible to add another round to the magazine.

The Shooting Star follower is still the only one that allows for a reliable flush-fitting, extra-capacity magazine. Because the follower itself is a leaf spring, it adds to the tension of the coil spring. Without the added tension of the Shooting Star follower, the coil spring alone would not yield the reliability and service needed for extra capacity in a flush-fitting magazine. In past decades the Shooting Star follower design has been licensed and used by most of the top of the line 1911 manufacturers. To this day, CMC designs and magazines are still being used by the highly esteemed custom shops of Colt® and Springfield Armory®.

  It was February 2014 and Chip McCormick was unable to sleep. The wheels of his mind were churning and since he was unable to stop them, he turned his attention to a problem that he had been trying to solve for 20 years. When the feed lips of a 1911 magazine are stressed they warp. Slam a fully loaded 10-round, .45 ACP magazine into a 1911-style pistol that has the slide locked back the magazine comes to a sudden halt. Inertia throws all of the weight of the ten rounds of .45 ACP ammunition against the thin walled lips of the magazine. Do it repeatedly and the lips deform.

Ten rounds of 230-grain .45 ACP ammunition weigh 42.8% more than seven rounds of the same hardball ammunition that fill a standard 1911 magazine. Those thin-walled feed lips of the old G.I. issue magazines also take a beating when they are dropped on the ground.

Chip long ago had addressed all of the issues of prevalent in old style 1911 magazines. He used premium steel and space-age design and manufacturing processes to produce the highest quality magazines available for 1911-style pistols. CMC magazines are “combat proven” to last longer than any of the cheap 1911 magazines available to the inexperienced shooter.

Always looking to provide the 1911 shooter with an edge, from having an 8th live saving round in a standard length magazine or 10 rounds in an extra capacity magazine, Chip’s goal has always been to give the 1911-user the ultimate feeding device. Ironically his development of the 10-round 1911 magazine in 1995 created a problem for anyone who abused their magazines, especially by slamming them when practicing “slide-lock” reloads and dropping them on concrete. Under such abuse it is only a matter of time before any 1911 magazine’s feed lips will fatigue and deform making them unreliable or inoperable.

The most obvious solution would seem to be simple, just increase the thickness of the magazine tube material. However, John Browning never envisioned such abuse and his original design for the 1911 pistol did not leave any extra space in the magazine well for using a heavier gauge material.

On that February night, the idea finally came to Chip, add extra material on the end of the feed lips and form that material inward to construct a dual walled feed rail™ system. His rails would replace the 105-year old thin walled feed lips design and make it obsolete. 

The Patent Pending Feed Rails™ technology is the first durability enhancement to the feeding device of the 1911 pistol. It is the most recent improvement to magazine design to come from Chip in over 30 years. Chip’s magazine innovations started with his extra capacity 8-round .45 ACP Shooting Star magazine and his 10-round .38 Super Match Grade CMC 1911 magazines.  

The Railed Power Magazine™ or RPM™ is a truly revolutionary new design for 1911-style pistols. It is the new ultimate in 1911 ammunition feeding devices. But great ideas need to be backed up with design and manufacturing processes. The concept of creating “Feed Rails” inside the tube of a 1911 magazine required complex tooling and manufacturing process that in themselves have turned out to be so unique and novel that they are patent pending as well as the design of the RPM.

After many months of research and development the complex engineering task of creating a cost effective process for producing the dual-walled Feed Rails, the first proof of concept prototypes were finally ready. It was time for Chip and his team to begin the task of testing prototypes of the RPM in .45 ACP.

During the evaluation period several important features were learned about the patent pending Feed Rails. First, it was thought that the doubling of the material would double the strength of the feed lips. Instead according to the engineers on the project they felt the elliptical cross section of the Feed Rails were substantially stronger. They predicted that the feed rails could be four times or more durable than feed lips. And in testing the RPM prototypes, in some cases the increased durability exceeded four times the strength of feed lips.

Another discovery was the radius of the Feed Rails engages the radius of the cartridge case with less friction than sharp edge of common feed lips. Gone were any deep scratches imparted by cheap feed lips on the cartridge case. With the new RPM magazine the .45 ACP cartridge glides out of the tube and the Feed Rails releases the cartridge with unparalleled smoothness. 

The results of the prototype testing were simply amazing.

With the massive durability of the Feed Rails being tested and proven out, Chip next turned his attention to increasing the strength, service life and reliability of the spring in the RPM. Fatigued springs account for about 15% of the stoppages in most magazines. By redesigning the follower and the interface of the integral base pad/base plate of the RPM, Chip was able to use 19 coils of rocket wire spring in the 10-round extra capacity model. The 8-round RPM has 18 coils of rocket wire in it, more than any other 8-round magazine on the market. These increases in spring strength and service life are an appropriate match up with the durability and service life of the Feed Rails. 

Chip McCormick is a name that most shooters in the past three decades associate with outstanding 1911 magazines and with good reason. Tens of thousands of law enforcement and military customers such as FBI, Marine RECON, Army Special Ops, and LAPD SWAT require reliability and service life second to none in their 1911 magazines and they have used them from war zones around the globe to the streets they patrol in America. CMC magazines have proven their durability for these public servants and it is no wonder that Chip McCormick magazines are also trusted by some of the finest athletes in the shooting sports world. 

What many do not know is that those magazines are the result of a relentless pursuit of excellence and maximizing reliability and durability under all conditions. 

Because the military and law enforcement loves CMC mags, Chip never forgets that they might be used in all sorts of harsh environments. Because of that, he designed his follower with the least amount of surface contact with the inside of the tube. Unlike other followers, steel or plastic, that require front and back downward extending guides and/or downward extending skirts for stabilization, a CMC magazine is as near impossible to be locked up by dirt, sand, or grime as it gets.  

But innovator that he is, Chip took it a step farther. The already Patented RPM follower is also patent-pending for another innovative design function for flexing the top and bottom halves of the RPM follower from side to side to further induce positive engagement of the slide stop upon last shot fired. Anyone with law enforcement, military or competition training knows how critical it is for the 1911-style pistol to lock open upon the last shot being fired. For law enforcement and military operators it can mean life or death in a lethal confrontation. For the shooting competitor it can mean winning or losing a local match, a national or world championship.

In addition to having had an amazing professional shooting career, Chip is a brilliant inventor. He is the inventor of the drop-in match AR trigger; he has conceptualized a world class competition holster and created several other innovations in the manufacturing world. The later includes ushering Kimber into the 1911 market and changing the way that most 1911s are manufactured. The point is that his mind never stops. The revolutionary new RPM magazine is the most recent result of his persistent focus on excellence.
