Stopped by CZ Custom yesterday and picked up my Rami that had the custom decocker hammer and tune done by them. I cannot tell you what a difference it made. The decocker is so smooth and easy to use, just a little pressure and hammer drops. In double action, after taking up slack, it is awesome. Single action is whisper smooth. I only had 125 rounds thru it. After shooting at the range this morning, at 12 yards, the groups could be covered by a half dollar. BUT, I am 76 years old and blind and shake like a three leg cow in a canoe.... WELL WORTH THE MONEY IMHO.......
