Rival Arms Grip Plug for Glock Gen4 — Black Anodized

Rival Arms’ Grip Plug fills the grip cavity of compatible Glock Gen4 frames to improve balance and limit debris ingress. It is CNC-machined from aluminum and finished in a hard black anodize for durable surface protection. The added mass in the lower frame can reduce perceived recoil and support more consistent follow-up shots. This plug is not compatible with Glock models 36, 42, or 43.
