Shield Arms S15 +5 Magazine Extension – Mud

The Shield Arms S15 +5 Extension increases capacity of S15 magazines by five rounds, bringing total capacity to 20+1 in a Glock 43X or 48. This extension maintains a slim profile while providing significant additional firepower without adding excessive length to the grip. It's designed specifically for use with Shield Arms S15 magazines and will not function with factory Glock magazines.

Machined from steel with a durable mud-colored finish, the extension replaces the factory magazine baseplate. Installation requires no gunsmithing—simply remove the existing baseplate, insert the included spring and follower components, and attach the extension. The kit includes all necessary parts for installation. Note that extended magazines may affect concealability and holster compatibility.
