Discover micro-compact concealment paired with full-size capabilities with the Sig Sauer® P365 Fuse Semi-Auto Pistol with Romeo-X Compact Red-Dot Sight. The Fuse combines 21+1 magazine capacity with a thin, 1"-wide grip while also delivering the accuracy capabilities you'd expect from a large-framed pistol due to the extra length found in the 6-7/8" slide. The long slide also features an optics cut and aggressive serrations for ease of weapon manipulation. The carbon steel barrel comes in at 4.3" and features a super-durable DLC coating. The polymer LXG grip module is topped off with a laser-engraved texture, promoting positive grip and control. Interchangeable backstops are included in small, medium, and large to offer a tailored fit to the shooter's hand. A nickel-plated, flat-faced trigger upgrades accuracy while offering stylish looks. The slide also includes a fiber-optic front sight and a black serrated rear sight in its own dovetail, separate from the optics plate.
