The

TRICK

if I may.
I've been shooting pistols off-and-on since the mid '70's, and when I started, I was appallingly lousy; I still am, but at least now I know why. We had a "ladies night" at our club last Fall (it was actually a lovely sunny morning). Several of them had never held a pistol in their lives; we were on the 20-yd steels range, and after I told them the trick, several of them hit everything they shot at, first time, every time. I was blown-away, to be honest; these girls were shooting as well as I ever did, the first time out.
So, what's the trick? (I know, just about now you think I'm an arrogant jerk who doesn't know anything about anything - well that's all true,

but anyways...) it's real simple. The human body makes a lousy shooting platform; here you are holding a heavy lump of metal (or polycarbonate) out on the end of two trembling stalks of bone and gristle, trying to line-up three separate points (backsight, foresight and target) with eyes that, if they're as bad as mine, can't focus on any one of them anyways. But what makes it worse is that when you want to pull the trigger, your fingers are all wired together and it's almost impossible to move one finger without moving all the others too, which throws-off your point of aim. How bad is it? Place your hand palm-down on the table in front of you, with the middle finger folded-under, and try to lift the third finger off the table -
- you can't do it, you can not even twitch that finger - it drives me crazy!
So knowing that all your fingers are wired together, the TRICK is to concentrate really hard on only moving the TRIGGER FINGER, and
PULLING the trigger straight back. It helps to have a .22 pistol with a lovely light trigger pull, and put a couple boxes of ammo downrange really thinking about moving only the trigger finger and pulling the trigger straight back. Your shooting to the left means that you're shooting right-handed and jerking the trigger; it pulls the gun to the left. I shoot left-handed and when I shoot fast, most of 'em shoot to the right; "SWMBO" is right-handed and when she shoots fast, most of 'em go to the left. As everybody else pointed-out, get some snap-caps and practise your trigger pull; you're trying for the gun absolutely not moving at all when it goes 'click', and then you know your trigger control is perfect.
I hope it works as well for you as it did for those girls at the ladies' night.
