Red Dots That Fit the Sig Sauer P365 XMacro
16 red dots in our database fit the Sig Sauer P365 XMacro directly, on its factory RMSc / SIG-LOC Compact optic cut. Standard XMacro SKUs carry the RMSc-pattern cut and are straightforward. The -RXSL SKUs are the one place in this family where we will not claim certainty: Sig’s spec field still lists RMSc on guns that ship with a factory-mounted ROMEO-X SIG-LOC, and SIG-LOC optics need the SIG-LOC cut. We have marked that row as likely rather than verified and said so on the page instead of picking whichever answer sounded tidier.
- Standard P365 XMacro SKUs use the RMSc-pattern cut, read per-SKU from Sig’s spec sheets in September 2026.
- On -RXSL SKUs our fit data is marked likely, not verified: Sig’s spec field shows RMSc while the gun ships with a factory ROMEO-X SIG-LOC, and per sigsauer.com/sig-loc a SIG-LOC optic requires the SIG-LOC cut. If you own one, confirm against your own slide before ordering.
- The XMacro uses the same magazine as the P365 FUSE, so a carry setup built around one feeds the other.
- 16 optics fit the P365 XMacro as a direct mount; 15 of them have live, feed-verified prices today.
- The least expensive with a verified price right now is the Sig Sauer Romeo RS Compact at $149.99.
- 9 of the fitting optics are enclosed-emitter designs, including the Osight S.

Does the Holosun 507K fit the Sig P365 XMacro?
Yes on a standard RMSc-pattern XMacro. The 507K X2 uses the Holosun K-series footprint, a modified RMSc, and mounts directly with no adapter plate.
What optic cut does the P365 XMacro use?
The RMSc pattern on standard SKUs, read per-SKU from Sig’s spec sheets in September 2026. The -RXSL SKUs are the open question — see the note on this page about Sig’s conflicting spec field.
Do the -RXSL XMacro SKUs have the SIG-LOC cut?
Probably, and we have marked it likely rather than verified. Sig’s spec field lists RMSc for those SKUs, but they ship with a factory-mounted ROMEO-X SIG-LOC, and Sig states that SIG-LOC optics require the SIG-LOC cut. The two claims cannot both be right, so we are not asserting either one.
Do the P365 XMacro and P365 FUSE take the same red dots?
The footprints overlap, but the defaults are reversed: the XMacro is RMSc-pattern as standard while the FUSE defaults to SIG-LOC Compact and carries RMSc only on its -RS SKU. Read the page for the gun you actually own rather than assuming the family shares a cut.
Is the P365 XMacro optic-ready from the factory?
Yes. Every current XMacro SKU ships cut for an optic under a removable cover plate; the question is only which pattern, and that depends on the SKU.
