Red Dots That Fit the Sig Sauer P365 XF DH3 AXG
15 red dots in our database fit the Sig Sauer P365 XF DH3 AXG directly, on its factory RMSc optic cut. This is the simple one. Both current XF DH3 AXG SKUs carry the same RMSc-pattern cut, so unlike most of the family there is no SKU suffix to decode and no SIG-LOC variant to watch for — if the optic is on this page, it mounts on your gun. The alloy AXG grip module and the integrated compensator make it the heaviest, flattest-shooting gun in the P365 line.
- Both current P365 XF DH3 AXG SKUs use the RMSc-pattern cut — one cut across the whole model, read per-SKU from Sig Sauer spec sheets in September 2026.
- Its non-AXG sibling, the XF DH3, does split by SKU: the -RXSL version is SIG-LOC Compact. The two models are not interchangeable on this point.
- 15 optics fit the P365 XF DH3 AXG as a direct mount; 14 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.
- 8 of the fitting optics are enclosed-emitter designs, including the Osight S.

What optic cut does the Sig P365 XF DH3 AXG use?
The RMSc pattern, on both current SKUs. It is one of only two models in the P365 family where a single cut covers the whole line, so no SKU decoding is needed.
Does the Holosun 507K fit the Sig P365 XF DH3 AXG?
Yes. The 507K X2 uses the Holosun K-series footprint, a modified RMSc, which mounts directly on this model’s factory cut with no adapter plate.
Is the XF DH3 AXG the same optic cut as the XF DH3?
Only partly. Every XF DH3 AXG SKU is RMSc-pattern, while the plain XF DH3 is RMSc on 365XF-9-DH3 and -10 but SIG-LOC Compact on 365XF-9-DH3-RXSL. Buying an optic for the wrong one of these two is the realistic mistake.
Do I need an adapter plate for the P365 XF DH3 AXG?
No, not for anything on this page. Every optic listed is a direct mount on the factory RMSc-pattern cut. If an optic needs a plate, it is not in this list.
