taking a break after the pumping has got to be the first rule. a real good trigger next. as been said watching and learning from some .45 competition shooters would be real good. left hand in a pants pocket, good stance and a repeatable one. You may not realize it but even your foot ware has some thing to do with a good score. I shot .45 for a few years in a pistol league and was told that it would be illegal to wear ski boots for support in NRA matches. john
