I bought a Model 94 in Stainless a while ago and have issues with the cylinder freezing. It usually happens during DA shooting but will sometimes do it in SA as well. I though it was just new but after a couple of hundred rounds, it is still persistent. When it happens, I usually have to wiggle the cylinder to get it free. Any suggestions? Should I just send it back to Taurus? What are the procedures, do I have to contact them first and get a RMA, or should I take it to the place I bought it from and ask them to send it back?
