The SIG Sauer P365 Fuse 2A Edition is a 9mm Luger pistol that fuses full-size capacity with the P365’s micro-compact concealment, holding 21+1 rounds in a grip that is still just about an inch wide (brand part no. 365XF-9-CFO-2A). SIG Sauer stretches the Fuse’s slide to 6-7/8 inches, longer than any compact in its class, for a longer sight radius and improved control, and the optic-ready cut accepts a red dot while fixed fiber optic front and serrated rear sights stay usable on their own. The LXG laser-engraved grip module ships with interchangeable backstraps and a removable magwell, and a nickel-plated flat-faced trigger rounds out the controls. It ships with four magazines, two 21-round and two 17-round, giving shooters the option to run maximum capacity or a more concealable flush fit.
