Xtech Tactical MTX Magazine Extension Features The Xtech Tactical MTX Magazine Extension lets a Sig Sauer P365 owner gain the grip length and feel of a P365X or P365XL simply by swapping their factory 10 round magazine s components. This is especially valuable in states restricting magazine capacity to 10 rounds since shooters there can still improve grip ergonomics without changing capacity. The patented extension design is engineered to work on the SIG magazine body s inward-facing tabs a feature that other extension designs on the market are unable to accommodate. This compatibility also extends to the Wilson Combat P365 frame broadening the extension s usefulness across the platform. An included replacement spring was engineered specifically for the P365 magazine which Xtech Tactical says ensures unmatched reliability along with proper last round bolt hold open function. Molded from durable injection-molded polymer in black the extension is built to handle repeated use without cracking or deforming. Installation is straightforward requiring only a swap of the factory magazine s components to achieve the improved grip length. The Xtech Tactical MTX Magazine Extension is for sale at GrabAGun for Sig Sauer P365 owners who want a longer more comfortable grip without giving up their factory capacity.
