The SIG Sauer P365-XMACRO COMP is a high-capacity micro-compact designed for everyday carry with enhanced performance. Engineered for shooters who demand maximum round capacity in a concealable package with reduced muzzle flip, this model has become one of our most consistent sellers since we added it in early 2024. Its popularity is driven by a blend of capacity, shootability, and SIG’s proven reliability.
Key Features
- Integrated Compensator: The slide-mounted ported barrel comp reduces muzzle rise for faster follow-up shots and improved control.
- 17+1 Round Capacity: Comes standard with two 17-round steel magazines, offering micro-compact dimensions with near-full-size capacity.
- Optics-Ready Platform: The X-RAY3 day/night sights co-witness perfectly with an installed SIG ROMEOZero Elite or other micro red dots on the removable rear sight plate.
- Enhanced Grip Module: Features an aggressive texture and a slightly longer beavertail for a secure, high-handhold that manages recoil effectively.
- Flat Trigger: SIG’s smooth, flat-faced trigger provides a crisp, consistent break for improved shot placement.

Frequently Asked Questions
Is the compensator built into the barrel or slide?
The compensator is integrated into the slide itself. The barrel is ported, with corresponding ports machined into the top of the slide. This design reduces overall length compared to barrel-mounted comps and is a key part of the XMACRO COMP’s control system.
Will this fit in a standard P365 holster?
No. The XMACRO COMP’s slide width and integrated comp require a holster specifically designed for the XMACRO series. The grip module is also wider to accommodate the 17-round magazine. Ensure any holster is listed as compatible with the P365-XMACRO or XMACRO COMP.
Why is this model so popular at your shop?
It hits a sweet spot. Customers appreciate the high capacity and the noticeable reduction in perceived recoil from the comp, making it a favorite for range use and training—we consistently see a sales spike on weekends for range day purchases. It’s become a regular reorder item for us due to its consistent demand.
