The Sharps Bros grip module for the Ruger RXM is machined from billet 7075 aluminum and finished in bronze Cerakote with blacked-out grip panels. It replaces the factory polymer grip module on the RXM and gives the pistol a rigid metal frame shell. Sharps Bros runs a steeper grip angle than the factory module and adds thumb ledges on both sides. You get a higher, more locked-in hold, and the support-hand thumb has a fixed place to index for better recoil control during fast strings. Features: Machined from billet 7075 aluminum Bronze Cerakote finish Blacked-out grip panels Steeper grip angle than the factory module Thumb ledges for a consistent support-hand index Replaces the factory Ruger RXM polymer grip module Fitment: Ruger RXM pistols only. It does not fit other modular pistols. The aluminum module feels different from polymer, so dry-fire with it before you carry or compete. After you move your internals over, do a full function check: trigger reset, slide travel and magazine seating, before live fire.
