ProMag Glock 21/30 45 ACP 22rd Magazine

The ProMag GLK-A17 holds 22 rounds of 45 ACP and fits the Glock 21 and the compact Glock 30. The body is DuPont Zytel based polymer over a full length steel insert, stamped and welded like the factory magazine.

The follower is injection molded and the spring is heat treated chrome silicon wire. Twenty two rounds of 45 is a long stick, so this one lives at the range or next to the bed rather than on the belt.
