This adapter plate is the perfect solution for Glock owners who want to add a Holosun 507C, 407C, 508T, or Trijicon RMR/SRO to their slide while preserving OEM integrity. It’s ideal for those seeking a backup or non-permanent optic setup — great for concealed carry, range use, or testing a red dot before committing to slide work.

Machined from aerospace-grade materials and finished with a durable hard-coat anodizing, this plate delivers a rock-solid mounting surface while maintaining optimal sight picture alignment. Whether you’re training or carrying daily, the GLX-RSH helps bridge the gap between standard Glock slides and modern red dot performance.

A: It supports Trijicon RMR, SRO, and Holosun 407C, 507C, and 508T.
