I carry a .38 special for CC. 4 inch barrel, medium frame. How do you rapid fire a revolver without being abusive wearing down the bolt and cylinder? I try to sqeeze off each shot more and more quickly with quick finger work while trying not to whiplash the finger snapping the trigger back. Trying to get off 2 to 4 shots a second. I try to take my time without taking my time so to speak thinking about the squeezing off the next shot instead of just wildly jerking back the trigger as hard and fast as I can. It seems partially psychological than physical. Any recommendations?
