Description
This Apex Optic Mount gives your Sig Sauer P320 with an RX Classic or RX Pro slide cut a secure, durable platform for mounting an Aimpoint ACRO P-1 or P-2, Steiner MPS, or Lead & Steel Pandora PB-3. Priced at $75, it is a direct-fit solution designed to handle the rigors of daily carry in Florida’s coastal environment.
Machined from a solid billet of steel, this mount resists corrosion far better than aluminum alternatives. The black oxide finish adds another layer of protection against humidity, salt air, and sweat — common concerns for anyone carrying near the water. You get a mounting system that won’t rust or degrade over time, keeping your optic securely in place.
The mount includes an Optic Sub Plate that allows the ACRO locking bar to fully engage. This prevents the optic from walking or shifting under recoil, even during heavy use. For EDC, that means zero retightening or checking before you leave the house. Your zero stays true, and the optic stays put.
Key benefits for your daily carry:
- Corrosion-resistant steel construction — built to handle Florida’s humidity and salt spray without pitting or rust.
- Secure optic lockup — the sub plate ensures full engagement of the ACRO locking bar, stopping movement and damage from repeated firing.
- Low-profile design — keeps your optic close to the slide for a streamlined draw and reduced snag risk.
- Compatible with factory Loaded Chamber Indicator — no loss of function on models that include this feature.
- Model-specific fit — designed exclusively for P320 slides with the RX Classic or RX Pro cut. If your slide has the rev2 cut (SKU includes “-R2”), use part #112-009 instead.
