Adapt Your Glock for a Closed Emitter Solar Powered Optic

Take your Glock MOS pistol to the next level with the Holosun 509T Optic Plate Adapter. This part helps you not stack adapter plate on adapter plate like a Jenga tower by giving the 509T a simple and low-profile way to mount directly to your Glock MOS pistol. Combine the legendary reliability of the Glock with the enclosed red dot Holosun 509T for any shooting situation. When it comes to reliability and performance, settle for nothing less.

Seamless Compatibility

Converts the Glock MOS footprint on your slide to securely mount the Holosun 509T and SCRS red dot. The SCRS is meant for rifles so it will sit a little higher and not a flush as the 509T but it can be used. The SCRS may also not work in conjunction with certain rear sights.

Strong and Secure Adapter

The plate and screws are made from 6061 T6 Aluminum to avoid issues such as bending, warping, or breaking that other adapter plates that use weaker metal can have. Additionally, this adapter plate has been tested to withstand rigorous use and heavy recoil, ensuring your optic stays secure and zeroed.

Low-Profile Design

Maintaining a thin and unobtrusive profile keeps your firearm looking good and doesn’t raise your optic as high as other optic plates.

Long Term Durability

It provides a rock-solid connection between the optic and slide, preserving your zero for consistent accuracy. The enclosed design of the 509T, combined with this adapter, ensures unparalleled reliability by protecting the red dot emitter from dirt, dust, and debris—ideal for tactical, competitive, and defensive shooting.

Simple Installation

Comes with all the necessary hardware, allowing a straightforward installation to easily and securely mount your optic without compromising performance or needing to take your firearm to a gunsmith.
