Details
The Apex Optic Mount is designed to securely mount the below listed optics to the Sig Sauer P320 slide with the RX Classic cut or RX Pro cut. The Apex Optic Mount is machined from a billet of steel and black oxide finished. The inclusion of the Optic Sub Plate allows the Acro Locking Bar to fully engage the mount to prevent walking and damage from heavy use.
Optics that fit this mount:
- Works with models equipped with the factory Loaded Chamber Indicator
- The Apex Optic Mount is model-specific. Please see part #112-009 if your P320 has the rev2 slide cut (will have "-R2" in the SKU).
For Use In These Guns
Part# 112-011: Specifically for use with Sig Sauer P320 pistols with an RX Pro slide cut. If your pistol came with the Romeo 1 Pro, this is the mount you need.
- Any Sig P320 with "RXP" in the SKU
Part# 112-012: Specifically for use with Sig Sauer P320 pistols with an RX slide cut. If your pistol came with the Romeo 1 (original, not Pro), this is the mount you need.
- Any Sig P320 with "RX" in the SKU
Does Not Fit These Guns
Not for use on the 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
