Rival Arms’ Grip Plug is constructed of CNC-machined aluminum and is compatible with your Glock Gen 4 except 36/42/43. The grip plug features a hard black anodized finish for durability and corrosion resistance. This precision-engineered accessory improves both form and function—it helps improve the balance and prevent debris buildup in the grip of your Glock.
With the weight increase in the lower portion of the frame, felt recoil is reduced making follow-up shots faster and more consistent. The result is enhanced control and faster target reacquisition during rapid fire sequences. The product comes with a Limited Lifetime Warranty, backing Rival Arms’ commitment to quality.
