My club does the “ NRA National Gallery Pistol” course once a week. You have to shoot with one hand. I’m happy if I get it on the paper my shoulders are so arthritic.
I have several red laser pens and practice eye-hand coordination, everyday. Since taking a combat/self-defense course from a Lt (now Chief) in Southern York Regional Police, I don’t bother w/ 3-pt Weaver Stance; I fast draw and shoot from hip. I’m hitting 1” groups of 3 in center mass, groin and head consistently. I have a sometimes painful left rotator cuff, so it’s only used when I do ‘weak hand’ shots, same draw routine.
