Shield Arms S15/S10 Magazine Extension +2 – Glock 43X/48

The Shield Arms S15/S10 Magazine Extension adds two rounds of capacity to your Shield Arms S15 or S10 magazine, pushing a Glock 43X or 48 to 17+1 (S15) or 12+1 (S10) without sacrificing concealability. This extension maintains the slim profile that makes these pistols ideal for concealed carry while giving you the extra rounds that can matter in a defensive scenario.

Machined from billet aluminum with a black anodized finish to match Shield Arms magazines, the extension installs in minutes with basic tools—no gunsmithing required. The low-profile design minimizes printing and adds minimal length to the grip. Compatible exclusively with Shield Arms S15 (15-round) and S10 (10-round) magazines for Glock 43X and 48.
