One of the only thumb rests I know of for the CZ. This one is from Advance Ratio Sports and Tactical and is made for the CzechMate and Tactical Sport. CNC machined and hard coat anodized. Mounting holes are 9/16" center to center. Available for right hand shooters in Black, Red, Blue, Gray, Yellow Gold, and Purple for right handed shooters. Includes four M4 x 12 screws for mounting. Price is $47.
Note: it may be necessary to shorten the mounting screws as we have discovered some inconsistency in frame thickness on some guns.
