What’s Included
- SIG Sauer factory hard case (gray polymer)
- 3 × 12-round SIG stainless steel magazines (mix of USA & Italian manufacture)
- Spare SIG Sauer P365 XL factory polymer grip module
- P365 XL ROMEO Zero footprint optic cover plate (no screws)

The slide is finished in durable black Nitron and features front cocking serrations plus a factory optic cut matching the ROMEO Zero / Shield RMSc footprint, giving you immediate red-dot capability without aftermarket milling.
A serialized stainless steel fire-control unit (FCU) serves as the legal receiver, allowing easy swap-outs of grip modules; the installed Wilson Combat LXG grip delivers enhanced texture and a beavertail profile for improved recoil control.
The striker-fired action uses SIG’s flat-faced skeletonized trigger for a consistent, straight-back pull, while the XRAY 3 tritium sights provide a high-visibility green front ring in daylight and glowing three-dot alignment after dark.
The 3.7 in. stainless barrel, single-slot proprietary SIG rail, and 12 + 1 capacity strike a balance between compact dimensions and shootability, making this XL variant equally suited to concealed carry or range practice.
