Shield Arms S15 10-Rounds Magazine Extension Features The Shield Arms Magazine Extension is engineered specifically to work with the Shield Arms S15 magazine extending its usable capacity to 10 rounds while preserving the reliable spring tension and feed lips the S15 is known for. Built from aluminum the extension resists the wear and impact of repeated magazine changes and hard training use far better than a polymer baseplate would. Its black finish matches the factory magazine body so the completed assembly looks factory rather than bolted together. Because the extension ships pre-installed there is no fitting or pinning required before the magazine goes into service. This style of extension is a straightforward way to squeeze additional capacity out of a magazine platform shooters already trust without resorting to a bulkier aftermarket magazine body. The aluminum construction keeps the added weight low while still standing up to the drop-and-reload abuse common in competitive shooting and duty-style training. Carry shooters benefit from the extra round on tap while range and competition shooters gain a small edge in capacity between reloads. For Shield Arms S15 owners looking to extend their magazines without changing their load-out this extension is a simple direct upgrade.
