Product Description The Rival Arms Grip Plug is a precision CNC-machined aluminum upgrade designed for Glock Gen 4 pistols (not compatible with models 36/42/43). Installed in the grip cavity, it helps close the opening at the bottom of the frame to reduce debris buildup, while adding weight low in the grip to improve balance and help reduce felt recoil for faster, more consistent follow-up shots. Finished in hard black anodizing for durability, this grip plug is designed for a clean fit and straightforward installation.
