Thats what the salesman told me over time, that the action would loosen up over time. I am almost 25 and don't have 100 years to fix the problem. So I sold it and got my Smith that is smooth right out of the box.
I gave away to a good friend many years ago my S&W Kit gun, which was an excellent and accurate revolver. But my Colt Diamondback that I bought back in 1971 is hands down my favorite .22. Unfortunately, for some strange reason they're selling for more than many Pythons, which makes it hard for younger people to pick one up. It's an amazing revolver to shoot.
I bought a used Taurus model 94 revolver , which has the worst trigger pull of any gun I own. It beats the 1895 Nagant revolver. The various web sites I trolled claimed that no matter how much polishing you do to the part, the pull is still way high.
