The SIG Sauer P365 FUSE combines the high capacity and shootability of a full-size pistol with the slim profile of a concealed-carry handgun. Its 4.3-inch carbon steel barrel and extended slide provide a longer sight radius, improved control, and enhanced ballistic performance, while the slim grip module remains comfortable to carry. The optic-ready slide uses a compact Shield RMS-c footprint and pairs with a fiber optic front sight and black serrated rear sight for fast target acquisition. A laser-engraved LXG polymer grip module, interchangeable backstraps, removable magwell, and M1913 accessory rail support a secure, adaptable setup.
