The Magpul EHG RG9 is a replacement grip module for the Ruger RXM 9mm pistol. This one is the compact size in Black. It is a direct replacement for the factory Ruger RXM grip module, so you can change the feel and look of your RXM without buying another pistol. Magpul's Trapezoidal Surface Projection (TSP) texture gives a positive hold without the abrasiveness of aggressive stippling. The module ships assembled with a Ruger-manufactured magazine release, release spring, slide-lock spring and takedown-pin spring, so those small parts are already in place when it arrives. Features: Compact size, Black Magpul Trapezoidal Surface Projection (TSP) texture Ships assembled with a Ruger-manufactured magazine release, release spring, slide-lock spring and takedown-pin spring Direct replacement for the factory Ruger RXM grip module Fitment: Ruger RXM pistols only. It does not fit other modular pistols. Confirm the size matches your RXM setup before you order. After you move your internals over, do a full function check (trigger reset, slide travel and magazine seating) before live fire.
