My M18 is an invaluable teacher; it comes along on nearly every range trip, I shoot it two-handed, strong-handed, weak-handed, single, and double action. I do ball and dummy drills, shoot one, open the cylinder, rotate and close without looking, repeat once, then finish the cylinder. Consistent practice with a M18 shooting will do a lot to improve anyone’s sight acquisition, and alignment, trigger control, and follow-through.
