This is for all you smart 'smiths out there. I have a GP100 6" barrel. It misfires on the same cylinder just about every time. I did the spring kit to try to fix it and still the same problem. Single action is ok but the problem occurs in double action. Handoads FYI.:banghead: What could be the problem or should I send it out to a pro$$$ ?
Thanks

Call Ruger and tell them the problem, best way to get it fixed properly.

Only thing I can figure is that one of the chambers is cut a little too deep. That's gonna be a factory fix.
