This magazine fits the M1911 MK Series as well as the new M1911A1. It holds 21 rounds and is manufactured and assembled to the highest standards. The magazines, like the weapons they are made for, have a wide availability of replacement wear-and-tear parts available, and feature realistic round capacities to better suit training scenarios.

*Please note that although this magazine will fit and function perfectly with the M1911A1, it is the stock magazine for only the M1911 MK Series.
