I haven't seen the old saw, so I'll throw it in

" Revolvers for defense, semi's for offense"

My corollary is that people who INTEND to do harm move to increase capacity; people who intend to LIMIT harm move to increase efficiency

On a more personal note, I enjoy the interaction with my revolver. I supply the energy to make it work through my DA trigger pull . . .while springs are involved, they are not as "in control" of the outcome as in a semi-AUTOMATIC which depends absolutely on proper balance of recoil springs and magazine springs

As an instructor once said, "I'd rather be well hung than well sprung!"
