It seems I have a timing issue. This is my second Ultralite and my first problem. Double action firing causes the gun to bind up after the third shot. Single action shooting doesn't seem to bother it much. The cylinder is definitely off a hair when observed through the barrel in action.
I suppose the questions I really need to know are what are my options to fix this or is the cost likely to be more than the gun is worse. I'm of the understanding that timing issues are probably the worst problems to have with a revolver.
