C&H Precision SGXRSHGDT Sig P320 Legion Optic Mount Plate

The C&H Precision SGXRSHGDT optic mounting plate transforms your Sig P320 Legion (M17/M18) into a precision platform ready for modern red dot sights. This black anodized adapter plate bridges the gap between your pistol's slide and Trijicon/Holosun pattern optics, eliminating the need for costly slide modifications.

What Makes This Different

Unlike universal mounting solutions that compromise fit and function, this plate is precision-machined specifically for the P320 Legion series. The black anodized finish matches factory specifications while providing superior corrosion resistance. CNC manufacturing ensures consistent tolerances that maintain zero through thousands of rounds, something generic plates often fail to deliver.

Key Features

• Direct-fit compatibility with Sig P320 Legion, M17, and M18 pistols
• Accepts Trijicon RMR, SRO, and Holosun 407C/507C/508T optics
• 6061-T6 aluminum construction with Type III hard anodizing
• Precision CNC machining maintains +/- 0.001" tolerances
• Low-profile design preserves sight picture and holster compatibility
• Includes mounting hardware with thread locker pre-applied
• No permanent slide modifications required

Field testing demonstrates this mounting system maintains zero through rapid fire strings and environmental changes. Law enforcement agencies report consistent performance in duty applications, while competitive shooters appreciate the repeatable return-to-zero when swapping optics. The hard anodized surface resists wear from holster draw cycles and environmental exposure.
