Sig Sauer P365 FUSE, 9MM, 4.3″ Barrel, Black, (2)-21 Round, (1)-17 Round

Product Description

The Sig Sauer P365 FUSE is a striker-fired 9mm pistol with a 4.3″ barrel and 21-round magazines. It is a full-size pistol with an alloy frame, a black matte slide, and the AXG grip module. The part number is 365AXGF-9-BFO.

What sets the FUSE apart

Sig Sauer built the FUSE to give you full-size shooting with the concealment of a smaller gun. The long slide stretches the sight radius, which helps you aim and control the pistol. The 4.3″ barrel is meant to improve ballistic performance with defensive ammunition. The AXG grip module stays slim while holding 21+1 rounds.

The slide is optic ready, so you can mount a red dot when you want one. Until then, the fiber optic front sight gives you a bright point to pick up fast. The pistol comes with three magazines: two 21-round and one 17-round.

This pistol suits anyone who wants more capacity and a longer sight line than a typical small carry gun offers. It works for concealed carry, home defense, and range days.

Gear that pairs well includes a holster made for this pistol, a red dot sight, spare magazines, 9mm defensive and practice ammo, and a basic cleaning kit. Check holster fit against the 4.3″ barrel and optic-ready slide before you order.
