Shown unpainted for visability. This thumbrest is made from billet aluminum and cerakoted. It is designed to fit all models of Buckmarks and allows grip removal without having to remove thumbrest. Thumbrest has built-on guard to help prevent the thumb being pinched between slide and barrel. Thumbrests help control muzzle rise, increase grip strength, and promote consistent hand placement. The thumbrest requires the frame to be drilled and tapped. Gunsmith installation is recommended. The grip adapters shown in the pictures are not included or required with this thumbrest.
