Sig Sauer Optic Cut

Modular Precision. Tactical Superiority.

Transform your standard Sig Sauer into a modern combat-ready platform. Legion Precision specializes in direct-mount optic milling for Non-Optic Ready Sig slides. By bypassing factory adapter plates and “universal” systems, we provide a deeper, more secure seat that withstands the violent reciprocating forces of high-volume fire.

• Platform Compatibility: Sig Sauer P320 (all variants), P365 (Standard, XL, Macro), P226, and P229.

• Series: Optimized for Non-Optic Ready factory slides (Gen 1 & Gen 2).

• The Legion Edge: We machine every pocket to within 0.001 inch tolerances. This “friction-fit” interface ensures the optic body—not just the screws—absorbs the recoil, preventing zero-shift and screw shear.

• Internal Safety Retention: Our CNC paths are engineered to respect the critical striker safety and internal channels specific to the Sig P-Series and P320 architecture.

• Lead-Time: 7-10 business days. Starts the day we receive your slide. Note: Holidays and weekends do not count as business days.

Your Sig is the world’s most modular handgun. Give it the optic mount it deserves.

Tech Tip for Sig Owners: Many Sig P320 slides have an internal “loaded chamber indicator” (LCI) slot. At Legion Precision, our milling is compatible with most LCI-equipped slides, but we recommend checking if your chosen optic requires an LCI-delete or a specific relief cut, which we provide during the machining process.
