Questions & Answers
The description says RMR optic footprint? Is this accurate? Will This fit an SRO with no adaptation? Manufacturer Answer

The Sig P365 XL Slide has an RMRcc footprint. Other optics that will work are Shield RSMc, SMSc, RMSx, Holosun EPS Carry, Holosun 507k, Sig Sauer Romeo Zero & Romeo Zero Elite, and Swampfox Sentinel. An SRO would likely need an adaptor plate to work.

This slide is *chef’s kiss* by Jak, Verified Owner, April 24, 2025
Gray MDC slide looks and feels fantastic, especially paired with their Black DLC Barrel from the same brand. Best build I’ve put together for a Sig 365 on the Icarus Precision A.C.E. X-MACRO aluminum grip module.
