Xtech Tacitcal MTX 365 +3 9mm 13-Round Polymer Magazine Extension - Black

The Xtech Tacitcal MTX 365 is a +3 round polymer magazine extension built specifically for the Sig Sauer P365 9mm micro-compact. The base sleeve slides over the factory P365 10-round magazine and brings the carry pistol up to a 13-round capacity, while doubling as a pinky rest that gives the shooter a more secure full firing grip.

Molded from black polymer, the MTX 365 +3 ships with the longer replacement magazine spring needed to cycle all 13 rounds reliably. It uses an easy-loading follower design and preserves the factory last-round-hold-open function. The extension is built to fit the standard-grip factory magazine for the Sig Sauer P365 family of 9mm standard-frame pistols.

Installation is straightforward - remove the magazine from the pistol, drop in the included longer spring, slide the MTX 365 base extension over the factory baseplate, and reinsert. This listing is for the +3 magazine extension and replacement spring only; no factory P365 magazine is included.
