The Ruger Mono Grip requires no modification to the frame. These simple to install Hogue grips clip onto the frame with a steel stirrup that clips over the existing stock pin or bottom strap of the frame. The rubber grips install with no need for gunsmithing, and the installation is a simple sliding process. The single-piece construction makes it extremely durable, and the rubber material ensures a secure fit. The design of Hogue Ruger Handgun Grip No Modifiers features a patented steel stirrup that clips over the existing stock pin or bottom strap of the frame. The monogrip design gives the shooter a high hold on the backstrap, reducing recoil and allowing rapid fire recovery, especially when using a two-handed hold. The palm swells are ambidextrous, so that left and right handed shooters can enjoy an equally superior grip. Sleek, low profile, and incredibly easy to install, Hogue Handgun Monogrips are the superior choice for shooters who want a better fit.
