Shield Arms S15 9mm Luger 15 Round WITH/+5 Round Extension For Glock 43x/48 G3 BLK

The S15 +5 Magazine Extension represents the ultimate capacity solution for Glock 43X and 48 owners who prioritize maximum ammunition availability. While factory Glock magazines limit you to just 10 rounds, this extension—when paired with the Shield Arms S15 Magazine—delivers an impressive 20+1 round capacity that rivals full-size service pistols. This transformative upgrade makes the compact Glock 43X/48 platform viable for competitive shooting, home defense scenarios, and extended range sessions where capacity and reduced reload frequency are critical advantages.

Engineered from aerospace-grade 6061 billet aluminum and finished with durable Type-2 anodizing, the S15 +5 Extension combines maximum capacity with professional-grade construction. The design includes ergonomic index cuts for positive magazine extraction, an innovative easy-access floor plate that permits complete magazine maintenance without extension removal, and full compatibility with Shield Arms magwells and most aftermarket flared magazine wells. Each extension includes a specially engineered 12-coil power spring calibrated specifically for reliable feeding with the substantially increased 20-round capacity.

Whether you're a competitive shooter in USPSA Carry Optics division seeking every possible advantage, a homeowner who demands maximum defensive capacity, or a serious training enthusiast who wants to maximize trigger time between reloads, the S15 +5 Magazine Extension delivers full-size pistol capacity in your micro-compact carry gun. Backed by Shield Arms' reputation for innovation and American manufacturing excellence, this extension transforms your Glock 43X or 48 into a true multi-role platform.
