Description
This Apex Optic Mount gives you a rock-solid way to mount an ACRO, Steiner MPS, or Lead & Steel Pandora PB-3 directly to your Sig Sauer P320. If you’ve got a factory RX or RX Pro slide cut, this is the piece that makes it work — no guesswork, no adapters that shift under recoil.
Machined from a single billet of steel and finished with a black oxide coating, this mount is built to handle the real abuse of daily carry, range sessions, and hard use in the field. It doesn’t just sit there — it locks in. The included Optic Sub Plate lets the ACRO locking bar fully engage the mount, which stops the optic from walking forward or loosening up after a few hundred rounds. That’s a real problem with other mounts on the market, and this design solves it.
Key benefits for your P320:
- Steel construction — no aluminum, no flex. This mount holds zero and takes hits without deforming.
- Black oxide finish — resists corrosion and cuts down on glare. Keeps a low profile on your slide.
- Compatible with factory Loaded Chamber Indicator — you don’t lose that visual or tactile check. It works as designed.
- Model-specific fit — designed for the RX Classic cut and RX Pro cut slides. If your P320 has the newer rev2 slide cut (look for “-R2” in the SKU), you’ll need part #112-009 instead.
