SIG Sauer P365 Fuse 9mm - Semi-Automatic Pistol - w/ Romeo-RS Red Dot - 1x 17rd, 2x 21rd Mags

The SIG Sauer P365 Fuse is a striker-fired 9mm semi-automatic pistol with a 4.3-inch barrel, a 21+1 capacity, and an included Romeo-RS Compact 3 MOA red dot sight. It ships with three magazines — two 21-round and one 17-round — providing flexible capacity options out of the box.

The P365 Fuse is built on a polymer frame with a stainless steel slide finished in Nitron black. The slide features aggressive serrations and an optics-ready cut with the Romeo-RS Compact already installed. Iron sights consist of a fiber optic front and a black serrated rear.

The double-stack magazine configuration delivers high capacity in a concealable footprint. The laser-stippled X-Grip provides consistent texture for positive control during rapid fire. An M1913 accessory rail accommodates weapon lights and laser aiming devices. The pistol uses an internal safety system with no external manual safety.

The P365 Fuse is compatible with P365-pattern holsters designed to accommodate the 4.3-inch barrel length and a mounted red dot. The Romeo-RS Compact sits in the optics-ready slide cut without an adapter plate.

Overall length is 7.2 inches and weight is 23.1 ounces unloaded.

The included three-magazine kit with two 21-round and one 17-round magazine gives the shooter a flush-fit carry option alongside extended capacity magazines for range or duty use.
