Model/SKU: SGXRSHGDT | UPC: 616943733563
Mount your favorite closed- or open-emitter dot with confidence. The C&H Precision Optics plate for the SIG P320 Legion (M17/M18) provides a rigid, black anodized mounting solution that adapts your factory slide to popular Trijicon® / Holosun® pattern optics. Engineered for duty-grade repeatability, this low-profile plate delivers tight tolerances, steel-on-steel hardware, and a finish that shrugs off sweat, solvents, and daily carry—ideal for EDC, competition, or professional use.
Why Choose the C&H Precision Plate for P320 Legion
Rock-solid interface: CNC-machined plate with precisely located recoil bosses and robust fasteners to help resist shear forces under recoil.
Trijicon/Holosun pattern footprint: Designed to accept leading red-dots in the RMR-pattern family (and select Holosun models that share the pattern).
Optimized sight height: Low-profile geometry helps maintain a natural presentation and may co-witness with appropriate suppressor-height sights (verify your setup).
Duty-ready finish: Black anodized treatment resists corrosion, abrasion, and harsh cleaning chemicals.
Purpose-built for SIG: Fits SIG Sauer® P320 Legion slides, including M17/M18 variants (optic-ready); engineered around OEM tolerances for a clean, drop-in fit.
Compatibility Note: This plate adapts SIG P320 Legion (M17/M18) optic-ready slides to Trijicon/Holosun RMR-pattern optics (e.g., Trijicon RMR®/SRO® and select Holosun 407/507/508 series). Always verify your exact optic’s footprint and your slide cut before purchase.

Installation Overview (Read the Included Instructions First)
Unload & clear the pistol. Remove the factory cover plate from your P320 Legion slide.
Degrease the slide and plate interfaces; clean screw threads.
Seat the C&H plate into the slide cut, ensuring recoil bosses align fully.
Apply blue (non-permanent) thread locker to clean, dry screws.
Torque plate screws to the manufacturer’s specification with a calibrated driver.
Mount the optic to the plate and torque to the optic manufacturer’s spec.
Witness-mark all screws and confirm function; verify zero at the range.
Pro Tip: Record your torque values and ammunition choice in a build log. Re-check torque after the first 100–200 rounds or any hard travel.
Best-Use Scenarios
EDC/Duty: Closed-emitter or rugged open-emitter optics for weather-resistant reliability.
Competition: Faster transitions and measurable time gains with a stable, repeatable dot.
Training: Thousands of presentations without loosening hardware when installed to spec.
Care & Maintenance
Periodically inspect torque and witness marks.
Keep interfaces clean and dry; avoid over-lubrication around optic windows.
Replace screws that show wear; always use fresh thread locker on cleaned threads.
