LOK Grips created this brass backstrap that is CNC machined from solid raw brass and cerakoted black. Hexagonal textured pattern helps prevent grip from slipping and providing the perfect tration needed. Added weight helps mitigate recoil and stability.  Similar shape and size to large OEM backstrap.  Weight ~ 1.7 oz +/- 0.1 oz  Includes replacement roll pin (2mm x 18mm)
