Optic Mount for Aimpoint COA to SIG P320 Sig-LOC Slide Cut

Description

The Apex Optic Mount provides a direct, secure method for attaching an Aimpoint COA red dot sight to your Sig Sauer P320 pistol. This mount is specifically engineered for slides that feature the factory SIG-LOC optic cut, including the P320 Legion, M17, and M18 models (both military and civilian). It offers a stable platform that maintains zero under regular use, making it a practical upgrade for your handgun.

Machined from a solid billet of steel and finished with a black PVD coating, this mount is built for durability. The steel construction provides a rigid interface between the optic and the slide, which is critical for consistent performance. The mount uses the Aimpoint A-Cut geometry, ensuring a precise fit for the COA optic. This direct mounting system eliminates the need for adapter plates, keeping the optic low on the slide for a natural sight picture.

Key Benefits and Fitment:

• Direct Fit for SIG-LOC Slides: Designed to fit the slide of the Sig Sauer P320 with a SIG-LOC optic cut. This includes the P320 Legion, M17, and M18 models. It also works with the factory Loaded Chamber Indicator (LCI) on M17/M18 pistols, so you retain that feature.
• Secure Optic Mounting: The steel clamp and mount securely hold the Aimpoint COA, preventing movement during firing. The kit includes all necessary screws, each with a thread locking patch pre-applied. Torque all Apex screws to 15 in-lb for proper installation.
• Durable Construction: The billet steel body with black PVD finish resists wear and corrosion, suitable for regular range use and carry.
• Made in the USA: This mount kit is 100% manufactured in the United States.

Important Specifications: This mount is designed exclusively for the Aimpoint COA optic and the SIG-LOC slide cut. It is not compatible with other P320 slide cuts or other optic footprints. The mount does not include the optic itself.

Add-On Option (Coming Soon): A separate Apex COA BUIS Set will be available. This includes a replacement COA clamp with an integrated rear sight and a front sight of appropriate height. This backup iron sight option will be sold separately and allows you to maintain a sighting solution if the optic fails.

Priced at $135, this mount is a direct solution for P320 owners who want to mount an Aimpoint COA without adding unnecessary height or complexity. It focuses on a secure, reliable fit for your specific slide cut.
