The Shield Arms S15 +5 Magazine Extension (brand part no. SA-S15-ME-5-BLK) adds five rounds of capacity to the Shield Arms S15 magazine built for the Glock 43X pattern, turning a slim-frame carry gun into a higher-capacity option without a bulkier magazine body. Shield Arms carries the same easy-access floor plate design across its extension line, so the spring and follower come out without pulling the extension off the magazine for cleaning or service. It is finished in black to match the factory magazine. Like the rest of the Shield Arms lineup, it carries a lifetime warranty.
