Standard Adapter Plate — Trijicon / Holosun
Designed as a reliable upgrade for RDO-ready pistols, this adapter adds extra serrations on each side of the slide. The result: easier manipulation and cleaner slide racking, without needing to grab the optic itself. A low-profile fit ensures durability and everyday carry compatibility.
