Sig Sauer P365 FUSE Comp 9mm Pistol 3.7" Barrel with SIG ROMEO X Red Dot - 21 Rd

The SIG Sauer P365XF takes the award‑winning P365 platform and pushes it into true next‑generation territory. Built around a 3.7" integrally compensated barrel, the P365XF delivers flatter shooting, faster follow‑up shots, and reduced muzzle rise—all without adding length or bulk to the slide. This is the most controllable compact P365 to date.

Factory‑equipped with the ROMEO‑X Compact red dot using SIG’s new SIG‑LOC footprint, the P365XF arrives fully optimized for rapid target acquisition and low‑light performance. Paired with X‑Ray3 day/night sights, shooters get a bright, intuitive sight picture whether using irons or the optic.

The XMACRO‑style polymer grip module provides enhanced ergonomics, improved recoil control, and compatibility with SIG’s high‑capacity magazines. SIG includes three magazines—two 21‑rounders and one 17‑rounder—giving the P365XF an unmatched capacity advantage in the compact category.

A flat‑faced trigger, optics‑ready slide with FUSE serrations, interchangeable backstraps, and internal safety system round out a feature‑rich pistol built for concealed carry, duty use, or home defense. Lightweight, high‑capacity, and exceptionally shootable, the P365XF is SIG’s most advanced compact 9mm yet.
