Unlike about 99.9999% of the posters here, I don't claim to be an expert shot. I aint too bad with a rifle or shot gun though!
It takes practice (unless you’re very gifted) to shoot a pistol. Once a year (if that often) being qualified with a GI pencil isn’t enough. At the range I was comparing the police shooters with the other pistol shooters there (who probably shoot about a hundred rounds a week). Last time I was at the range I saw a lady being taught to shoot an automatic by a man who seemed to be pretty good. At first she had trouble staying withing the target frame at 15 yards. After about fifty shots she was hitting the center of the target with a group you could cover with your palm. But you need to stay in practice. I know an ex NY-police armorer and range officer who told me he had cops show up to qualify who couldn’t get their pistols out of their holster.
