Every person is different and has to find the best way. I tried different methods and picked the one that was best --then after a permanent elbow injury my way is a cross between two !
For multiple shots you must not have the gun move in the hand .For me that's no problem for 9mm, 40, 45acp with locked wrists.For 44mag I change -bending my elbows and using the elbows as shock absorbers without the gun moving in my hand.Practice, practice !!
