Description
The P365-XMACRO KIT is a complete upgrade platform for your SIG P365 series pistol. It’s designed for the shooter who wants the enhanced capacity, control, and optics-ready capability of the XMACRO frame without buying a whole new firearm. We’ve stocked this kit since early 2026, and it’s one our repeat customers frequently come back for. The key benefit is a direct, drop-in conversion that modernizes your existing P365 into a high-capacity carry or competition-ready piece.
Why This One?
- Complete Conversion: This is a full kit, not just a grip module. It includes the XMACRO grip module, a 17-round magazine, and a new magazine catch, providing everything needed for the swap.
- Enhanced Control: The XMACRO frame offers a significantly fuller grip with aggressive texturing, improving handling and recoil management over the standard P365 grip.
- Optics-Ready & Comp-Ready: The integrated compensator on the slide is designed to reduce muzzle flip, and the slide is cut for SIG’s ROMEOZero Elite optic footprint.
- Proven Reliability: It utilizes your existing, reliable P365 FCU (Fire Control Unit), maintaining the core function of your pistol while upgrading its form and capacity.
- Noted Quality: Our staff inspected the latest batch and noted the finish quality was excellent, with no visible tooling marks on the components.

Q & A
Will this kit work with my P365XL?
Yes. The P365-XMACRO KIT is designed to work with the Fire Control Unit (FCU) from any standard P365, P365XL, or P365X. You simply transfer your existing FCU into this new grip module.
Does the integrated compensator make a significant difference?
Yes, for most shooters. The comp is designed to redirect gas upward, countering muzzle rise. The effect is a flatter, quicker sight recovery between shots, which is noticeable during rapid strings of fire.
Are the standard P365 10/12/15-round magazines compatible?
No. The XMACRO grip module requires the specific 17-round magazines due to its longer grip frame. Your older, shorter magazines will not seat or function. This kit includes one 17-round magazine to get you started.
