Information on Sizing up your frame to the correct magazine
Simple Method for Determining Which Mags Fit Which 1911 Pistols

If you take a measurement perpendicular to the top of the pistol slide:

1. A 1911 pistol with a "full sized" receiver will measure 5.25 inches from the top of the slide to the bottom of the receiver. Thus, full sized 1911 mags fit full sized 1911 pistols. Detailed information about all CMC mags for full sized pistols is included in the chart above. 

2. A 1911 pistol with a "compact sized" receiver will measure 4.75 inches from the top of the slide to the bottom of the receiver. Thus, compact sized 1911 mags will fit compact sized 1911 pistols. Detailed information about all CMC mags for compact sized pistols is included in the chart above.

See the Pictorial example (below) for additional information on determining your weapons frame Size.
