TANDEMKROSS Accelerator Thumb Ledge for Ruger Mark IV 22/45

The TANDEMKROSS Accelerator Forward Thumb Ledge adds a dedicated support-hand contact point to the Ruger® Mark IV™ 22/45™. Often called a thumb rest or “gas pedal,” a forward thumb ledge gives your support-hand thumb a consistent place to index, promoting a firmer, more repeatable grip and better control of muzzle movement during rapid strings of fire.

The Accelerator’s scalloped, textured surface provides secure purchase without being abrasive, helping you settle the sights faster between shots on steel, paper, or timed courses of fire. Machined from aluminum and finished in a durable anodized coating, it weighs approximately 0.3 oz, so it adds control without upsetting the balance of the pistol.

Installation is simple and non-permanent: no drilling, gunsmithing, or modification to your frame is required, and the pistol can be returned to factory configuration at any time.
