SIG Sauer
Extended P365 with optic-ready slide and accessory rail
0-10 Scale Across 8 Axes
The P365 XL addresses the two main requests from P365 owners: an optic-ready slide and an accessory rail. The XL adds roughly half an inch to the slide and barrel, providing a longer sight radius and better muzzle velocity. The extended grip module accepts 12-round magazines standard (flush fit) while remaining compatible with 10-round P365 magazines.
SIG equips the XL with an optic-ready slide featuring a removable rear sight plate that accepts Shield RMSc footprint optics including the popular Holosun 407K/507K series. The integrated accessory rail allows mounting compact lights like the Streamlight TLR-7 sub. Despite these additions, the XL remains remarkably concealable - most shooters find it easier to shoot well than the smaller P365 while barely sacrificing concealment.
The P365 XL occupies the sweet spot for many carriers: large enough for confident shooting, small enough for all-day IWB carry, and equipped with the features (optics and lights) that modern defensive pistols should have. For many shooters, the XL is the ideal P365.
