SIG Sauer’s new optics-ready P365-FUSE chambered in 9 mm Luger features a long slide, 4.3-inch carbon steel barrel, 21+1 round capacity and the LXG (laser engraved X-grip) grip module.

Along with the aforementioned polymer laser engraved LXG grip module, the striker-fired SIG Sauer P365-FUSE sports a 1913 accessory rail, removable magazine well, interchangeable small, medium and large backstraps, plus a nickel-plated flat-faced trigger. Additionally, the optics-ready stainless steel slide features aggressive serrations with fiber-optic front sight and with black serrated rear sight.

The 4.3-inch long barrel, made from carbon steel, has a DLC finish. In addition, the stainless steel slide has a nitron finish.

P365-FUSE
Overall length of the SIG Sauer P365-FUSE is 7.2 inches, width is 1.1 inches and the height is 5.1 inches. Sight radius is six inches. Adding the ROMEO-X red-dot optic (not pictured) increases the weight to 24.8 ounces. As for the trigger, it is a nickel-plated one with a flat face.

 

The P365-FUSE ships with two 21-round and one 17-round magazines. For states with magazine capacity requirements, the P365-FUSE ships with three 10-round magazines.

The optics mounting footprint on the slide is for the Shield RMS-c. While the SIG Sauer P365-FUSE’s slide is cut for optics, it also has the previously mentioned iron sights—a fiber-optic front sight and black serrated rear sight.

SIG Sauer has also announced the P365-FUSE ROMEO-X, which includes a factory installed ROMEO-X compact sight crafted from 7075 aircraft-grade aluminum. The SIG Sauer ROMEO-X compact red-dot optic has a two-MOA dot, machined anti-reflection grooves on shooter-facing surfaces, distortion-free aspheric glass and the patent-pending Beryllium Copper flexure-arm adjustment system.
