The Recover Tactical GR2101 is a polymer Picatinny rail adapter designed to mount optics and accessories on Glock 21 Gen 1 and Gen 2 pistols. If you shoot a Glock 21 and want to add a red dot, laser, or light without gunsmithing, this rail adapter gives you a standard 1913 Picatinny platform to work from. It's a practical way to modernize an older frame or build out a duty or defense setup with the accessories you already own.
Made from black polymer, the GR2101 attaches directly to your Glock 21 Gen 1-2, providing a durable mounting surface that meets standard Picatinny dimensions. The polymer construction keeps weight minimal and won't interfere with the gun's ergonomics or reliability. Installation is straightforward and doesn't require permanent modification to your pistol.
Whether you're adding a compact reflex sight for faster target acquisition, mounting a weapon light for low-light work, or integrating a laser for training, this adapter opens up the full ecosystem of Picatinny-mounted gear. It's a no-nonsense upgrade for shooters who want more capability from a Glock 21 Gen 1 or 2 without the cost or complexity of a slide cut.
The Recover Tactical GR2101 is engineered for Glock 21 Gen 1 and Gen 2 pistols. Verify your Glock generation before purchase to ensure compatibility.
Any optic, light, or laser designed for standard 1913 Picatinny rails will mount to the GR2101. This includes red dot sights, magnified optics, weapon lights, and laser systems.
No. The GR2101 attaches to your Glock 21 without permanent modification to the frame or slide, allowing you to remove it if needed.
