The Adjustable Thumb Rest has dramatically increased my competition scores in NRA Timed and Rapid Fire at 25 yards. I'm back on target much quicker by controlling muzzle rise. A truly innovative and high quality product!! My only suggestions are: (1) The unit did not have enough set back on the upper portion to clear the side of my slide (1911 Single Stack). I tried this item on four different 1911 manufacturer's pistols, with the same result. A metallic metal shim of 0.020" (approximately 0.500mm), of the same rectangular shape as the bottom of the rest, with screw clearance holes, would be ideal to give the needed clearance without leaving an objectionable opening; (2) If the instructions mentioned the screws' thread size (4mm X 0.7 pitch), it would be a big help to those who do not have a metric thread gauge, in order to select the proper tap size for threading the mounting holes that have to be drilled into the side of the 1911's dust cover.

Most impressed with the quality of the thumb rest, it has been helpful in controlling recoil, thank you

Added the adjustable thumb rest to my CZ Tactical Sport and am very pleased with the results. It feels very natural and the double tap results are the best I've had.
