Shield Arms S15 Gen3 Starter Kit Glock 43X/48 9mm 15rd Magazine

The S15 Starter Kit is the simplest way into Shield Arms magazines: one S15 Gen3 15 round 9mm magazine and the steel magazine release it is built around. It fits the Glock 43X and Glock 48 and is the same length as the Glock 10 round magazine, so the grip stays flush.

Shield Arms says to replace the polymer magazine catch with its steel catch before running S15 magazines, and the kit includes one. Gen3 tubes have raised ribs on the back to match the Glock magazine position and a black nitrocarburized finish.
