ProMag Glock 21 45 ACP 13rd Magazine

The ProMag GLK-A14 is a 13 round 45 ACP magazine for the Glock 21. It matches the full size G21's standard capacity and also works in the Glock 30, where it extends below the shorter grip.

The body is DuPont Zytel polymer over a full length steel insert, the same layout as a Glock magazine. The follower is injection molded and the spring is wound from chrome silicon wire. A good spare to keep at the range or in the truck.
