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.
Steel Body Glock 43 / 43X / 48 / 19 / 17 Lifetime Warranty

Thinner walls than polymer, so more rounds fit inside the same grip footprint
OEM Reliability
Drops free, locks the slide back, and feeds the same ammo your factory magazines do
Hard-Wearing Finish
Corrosion-resistant coating stands up to carry sweat, dirt, and high-round-count training
Lifetime Warranty
Covered for life against defects in materials and workmanship, no questions asked
