A couple of friends just bought a pair of brand new stainless New Model Vaquero for SASS use. All four guns exhibit the same problem: the loading gates don't sit flush in the frame, whether the gates are open or closed. The gates projected far enough that they sometimes obstructed cylinder rotation with loaded rounds, i.e. the rim of a loaded round would occasionally catch on the gate or make cocking effort greater than normal. Is there a common problem here that I can address to help out my friends?
