SIG LOC mounting ensures the optic remains zeroed after thousands of rounds.
The XSeries grip module features aggressive texturing and an extended beavertail.

Frequently Asked Questions
1. Is the Sig Sauer P365 X Macro the same size as the P365 XL?
No, it is slightly taller and longer due to the compensator and 17-round grip module, but holster compatibility is often interchangeable.
2. Can I use P365 XL holsters with the X Macro Comp?
Many Kydex holsters designed for the P365 XL will work, but you must confirm open-bottom design for the compensator.
3. Does the Romeo X SIG optic co-witness with iron sights?
Yes. The X-Ray 3 day/night sights provide a lower 1/3 co-witness through the Romeo X window.
4. Is the compensator removable?
No. The compensator is milled directly into the slide and is not user-removable.
5. What optic footprint does the X Macro slide use?
RMSc / Shield footprint. It accepts Romeo X, Holosun EPS Carry, and Shield RMSc optics.

The X Macro has a compensator, higher capacity (17 vs 12 rounds), and a larger grip module. Recoil is noticeably softer.
7. Is this model California-legal?
No. This 17-round model is not on the CA roster. Check your local laws before ordering.

CR1632. Battery life is rated at over 20,000 hours on medium setting.
9. Does the pistol include a manual safety?
