Glock G17/34 9mm 33rd Magazine

Glock's 33 round 9mm magazine, listed for the Glock 17 and 34. The polymer body has a hardened metal insert, viewing windows show the round count, and the orange follower makes an empty magazine obvious.

New Glock magazines are stiff. Loading all but the last round and letting it sit a few days helps the spring settle before you fill it to 33.
