Pistol Magazines
S-Series · Z-Series · DS-Series
More Rounds. Same Pistol.
A steel body with thinner walls than factory polymer puts the extra rounds inside the grip you already carry — no grip extension, no longer magazine, no new holster.
First to Build a Steel Aftermarket Glock 43X/48 Magazine — The Industry Followed
Thinner walls than polymer, so more rounds fit inside the same grip footprint
Drops free, locks the slide back, and feeds the same ammo your factory magazines do
Corrosion-resistant coating stands up to carry sweat, dirt, and high-round-count training
Covered for life against defects in materials and workmanship, no questions asked
Find Your Fit
