for dang sure have ear and eye protection. and, when you go to your practice at the range, ignore what the other shooters are doing - as long as they are acting safely of course.
they, other shooters, are mostly there for the fun factor and will, tomorrow, enjoy telling others about how many hundred rounds they fired at the range yesterday.
don't get sucked into that - blasting away. you are there on a quest, to learn accurate shooting. shots fired cannot be recalled. where they are is where they are and it is best to concentrate on what you are going to do with the next one.
accurate handgun use is a skill that must be devoloped over a period of time. use your time to work at it. i know, blasting away is fun and i do my share, but, i do that After my serious work is finished.
Lordy, i hate to pick on another person's gun, and i apologize in advance, but no one else has mentioned this: your Ruger pistol is designed for offensive/defensive use, not target work, and is excellent at what it was designed for. those i have shot were smooth reliable operators and i admired them and made no complaint about 50 yard accuracy or lack thereof.
i thought they were at their best at 5 feet or so on silhouete double action. for a person that practices defensive shooting and makes no particular use of target shooting stance, sight alignment, blah blah, they are at their best.
get it out and put it to work on the BG. i settled on a G17 over a Ruger for capacity. 18 rounds of bad boys. one shot stop, hell, one magaziner stop sounds about right. a flurry of nines will stop a crowd from doing their deed.
people are fond of saying a gun is a tool, because it is true. one gun is for one thing, another gun is for something else. there are guns that do double duty. SnW revolvers come to mind. not the best in both worlds, but, certainly respectable. K19 is about top on the list and target 38s will surely fill a 10 ring at 50 yards in the hand of a "hard holder". .357s will do a satisfactory job on people and critters.
get the info from the Army Marksmanship Manual as suggested by another poster. that is good advice for anyone to take. i have a copy and have read it with great interest, several times. i helped get me past the 2600 "barrier" and stay well above it some 40+ years ago.
someone also said, in other words, that you could be "picking" at your trigger. meaning you wanted the gun to fire when when everything looks perfect, causing a little fudging of the gun. no matter how well aligned the sights or their position on the target, if you mess up on the release, all is for nought. so, don't stand there admiring your sight picture, get to work on that trigger.
and, don't despair. keep on working and it will come together for you.
good shooting.
