Good mags but… - FAB Defense ULTIMAG Glock 17 9mm Luger 18 Round Pistol Magazine

These are decent mags for the price. Initially they had a hard time feeding in my Dagger but once I put a few rounds through they started feeding fine. Also, they fit fine in my Glock 45, PSA Dagger Compact, and my Shadow Systems XR920, but are tight in my Zev Technologies OZ9C. While the seat in the Zev, it’s a tight fit and they don’t drop and have to be pulled out to do a mag change. I guess I’ll stick with my OEM Glock mags and Magpul mags for the Zev.
