I recently purchased an older model 60 Smith & Wesson J frame which was pretty dinged up.
Failed to fire about 30% of the time.
Tore the gun down completely meticulously cleaned it replaced the Springs,with Wolf Springs, honed the areas that were recommended to be honed.
Checked the hand, extractor, trigger and Hammer.
The gun now has a trigger pull of approximately 11 - 12 pound.
Still getting failure to fire on about 5 out of 50 rounds it doesn't matter what type or brand of ammunition I am using.
I am getting dimples in the primer from where the firing pin hits it, and on occasion if I cycle it through for the second time it will fire that round. Sometimes not.
Cylinder of seems to rotate properly although it is just a little loose.
I've owned a ton of jframes and never ever had a problem like this.
Any ideas or suggestions on how to remedy this problem would be greatly appreciated.
