- Sig Sauer pistols with a RX PRO slide cut
- If your Pistol came with the Romeo 1 Pro, this mount will fit your slide
- Any Sig P320 pistol with “RXP” in the SKU
- Also fits on all Sig P320 with the -R2 optic cut (M17, M18 and Legion Series pistols)
Does Not Fit These Guns
Does not fit:
Sig P320 RX (Classic) Optic Cut
Sig P320Max (This slide has an entirely different optic cut)
Older X-5 Slides - These slides have a cut that looks similar to the Sig-Loc cut, but with 2 distinct differences:
- The O.G. slide cut at the front of the mounting geometry in the slide is narrower than those on modern Sig-Loc cut slides
- Mounting Screw Holes are a different thread pitch than most other Sig Slides and we do not have screws to match them
