Bought a nice looking 617-10 4 inch revolver new over a yr ago and immediately found problems. Had the usual light strikes, spitting and I did not like the metallic sound of the action which I attributed to the hollow mim parts. My first thought was to try another mainspring and longer strain screw which made the trigger very bad but it was firing better. The longer strain screw caused the grip boss to be in the way so I had to trim the boss on both grips. I eventually decided to ditch the mim and replace with old K22 parts. I also experimented with a coil spring mainspring contraption. Kinda worked but this week I reassembled it back to almost original and started again. Kept the K22 hammer and trigger, long strain screw and standard flat mainspring. Replaced the firing pin and swapped out the cylinder lock with one with a better fit today. Fired 50 rds of federal over the last couple days with only 1 ftf but fired on a second hit. Since I swapped the cylinder bolt the lockup has zero movement, initially the cylinder had play which might have been causing the spitting I was experiencing. The new bolt seems to have eliminated the spitting. Thought that it needed forcing cone work but now maybe not. I did have a setback when the small hand torsion spring broke a leg. While the trigger pull is smooth those serrations on the trigger are not so I ordered a smooth wider target trigger via fleabay. I really like this Smith and think I’ve debugged it. I love his big brother.
