Recover Tactical GR4201 Black Polymer Picatinny Rail Adapter for Glock 42

The Recover Tactical GR4201 is a black polymer Picatinny rail adapter designed specifically for the Glock 42. If you're running a compact .380 ACP and want to mount optics, lights, or lasers without gunsmithing, this adapter lets you do it. Glock 42 shooters often find themselves limited by the slide's flat profile—this rail system opens up your accessory options while keeping the gun's slim profile intact. It's injection-molded polymer construction, so it's lightweight and won't add appreciable bulk to an already compact carry gun.

Installation is straightforward—no permanent modifications to your Glock 42 required. If you're building out a duty setup, a range gun, or just want better target acquisition with a red dot or mounted light, this adapter gives you the standardized Picatinny mounting platform you need. The black finish matches standard Glock aesthetics and blends in with most optics and accessories you'd pair it with.

This is purpose-built for the Glock 42's compact frame, so compatibility is exact. Whether you're a competition shooter, a home-defense-focused carrier who wants low-light capability, or someone who simply prefers the ergonomic feel of a mounted optic, the GR4201 removes the barrier to upgrading your gun's capability.
