The C&H Precision Weapons adapter plate lets you mount Trijicon RMR, SRO, or Holosun optics onto your Walther PPQ, Q4, or Q5 slide. If you're running one of these popular duty or carry guns and want to add a micro red dot—without buying a whole new pistol—this adapter bridges that gap. C&H machines each plate to tight tolerances on HAAS CNC equipment in coastal Georgia, then runs it through multiple quality checks before it ships. The result is a rock-solid mounting solution that doesn't compromise zero or reliability.

This adapter works with a wide range of optics: the battle-proven Trijicon RMR and SRO, or the versatile Holosun 507C, 407C, 508C, 508T, and 507Comp. Whether you're building a competitive gun, setting up for home defense, or upgrading a carry pistol, you've got options. The plate itself is 6061 aluminum for weight and durability, paired with stainless steel mounting hardware. Everything is made in the USA, and the small-shop quality control means you're not getting a mass-produced compromise.

Installation is straightforward for anyone comfortable working on their pistol. The plate mounts securely to your PPQ/Q4/Q5 slide, and your optic then sits on the C&H plate. No gunsmithing required, and no permanent modifications to your gun. If you decide to swap optics or go back to irons, you can do it without any hassle.
