When I dry fire the gun, sometimes it locks up and I have to release the trigger, then I can continue dry fire, carry up is good, this happens with snap caps too. It will cycle and then it just stops and will not cycle until I release the trigger.
This is why I always use factory rebound slide springs. I seem to have the problem only in K frame, not J, L or N.With a tuned revolver, you have to learn to move your trigger finger both ways. With stock springs, you can get away with letting the trigger push your finger forward, because the rebound spring is very heavy.
