The bushing has a torquing surface distributed about the head of the bushing to provide improved torque and alignment for the bushing as it is assembled and disassembled into the firearm frame. The bushing may include an O-ring on the bushing itself and an additional O-ring fitted on the grip screws. The bushings and tools for replacing the OEM bushings may be provided as part of a kit.
