Description
The Apex Optic Mount delivers a stable, dedicated mounting solution for attaching an Aimpoint ACRO P-1, P-2, Steiner MPS, or Lead & Steel Pandora PB-3 optic to your Sig Sauer P320. This mount is precisely machined from a single billet of steel and finished with a black oxide coating. It is built specifically for P320 slides that feature the factory RX Classic cut or the RX Pro cut — no adapter plates or additional modifications are needed.
One of the key benefits of this mount is the inclusion of an Optic Sub Plate. This plate allows the ACRO locking bar to fully engage with the mount, preventing the optic from shifting or walking under recoil. For shooters who put their P320 through heavy use, this translates to consistent zero retention and less maintenance over time. The steel construction adds durability without excessive weight, and the low-profile design keeps your sight close to the bore axis for a more natural aiming index.
Key features and real-world benefits:
- Direct fit for RX and RX Pro cuts: No need for aftermarket slide milling or bulky adapters. This mount drops onto your factory-cut P320 slide and accepts the listed optics securely.
- Works with factory Loaded Chamber Indicator (LCI): The mount is designed to clear the LCI found on many California-compliant P320 models. You retain the ability to visually and tactilely verify a round in the chamber.
- Suppresses optic movement under recoil: The sub plate and locking bar engagement keep the optic firmly in place. This is especially important for shooters who train frequently or use their pistol for defensive purposes.
- Model-specific design: This mount is for P320 slides with the RX Classic or RX Pro cut. If your P320 has the rev2 slide cut (look for “-R2” in the SKU), please see part #112-009 for the correct version.
Compatible optics:
- Aimpoint ACRO P-1
- Aimpoint ACRO P-2
- Steiner MPS
- Lead & Steel Pandora PB-3
