The C&H Precision Weapons Sig Z Romeo1 Adapter converts your Sig P320 Legion, M17, or M18 slide to accept compact red dot sights on the Trijicon RMR footprint. If you've invested in an RMR, SRO, Holosun 407C, 507C, 507Comp, or 508T—or prefer the C&H EDC-XL and COMP patterns—this adapter lets you run them on a modern Sig duty or carry gun. Built and quality-checked by C&H's small family-owned shop in Coastal Georgia, each plate is precision machined to tight tolerances on HAAS CNC equipment, then inspected multiple times before shipment to you.

The plate also includes a Glock-style rear sights dovetail, so you can mount iron backup sights alongside your electronic optic. That redundancy matters when you're counting on your gun to work—whether on the range, in competition, or on duty. Stainless steel hardware resists corrosion, and the mild-grade steel plate is engineered for durability under real-world use.

This is a straightforward milling solution: no gunsmithing required, and no permanent modifications to your slide. If you run a Sig P320 platform and already own a compact reflex sight, this adapter opens up your optic options without forcing you to buy another gun.
