SIG Sauer P365 XL X-Series 9mm with Wilson Combat Grip, Optic-Ready Slide & Night Sights
The P365 XL X-Series takes SIG Sauer’s popular micro-compact platform and stretches it just enough to deliver a longer 3.7" barrel, an extended 12-round grip, and a flat X-Series trigger. This example stands out with a factory optic-ready stainless slide and a Wilson Combat grip module that improves ergonomics and control without adding bulk.

What’s Included
- Wilson Combat P365 grip module (installed)

A modular stainless-steel fire-control chassis allows the P365 XL to accept caliber or size conversion kits, so the buyer can tailor the pistol to different roles. The installed Wilson Combat grip module features aggressive star-burst texturing and an extended beavertail that helps manage recoil during rapid strings.
The optic-ready slide ships from SIG with an RMSc/ROMEOZero footprint cut, letting you mount a micro red dot without an adapter plate. Front and rear cocking serrations provide positive purchase for slide manipulations, even with gloves or moisture.
Factory XRAY3 tritium night sights give a bright green ring up front and subdued rear dots for a fast, day-to-night sight picture. If you mount an optic, the sights sit low enough to co-witness through most slim red dots that share the factory footprint.
The X-Series flat-faced trigger breaks cleanly and resets shorter than the original P365 design, delivering a consistent striker-fired pull that supports accurate, fast follow-up shots. Combined with the 3.7" stainless barrel and 12+1 capacity, this XL variant balances concealability with shootability.
