Thumb Rests WITHOUT the flange will fit CZ models such as the CZ 975, 85, P-01, SP-01, original Tactical Sports as well as any other pistols from other brands after their frame is drilled for 2 holes. This thumb rest (without the flange) comes with two screws. Please note that depending on the thickness of the frame where the thumb rest will be used, users may have to file/shorten the screws down a little (or perhaps even buy longer screws on rare occasions).
