Pardon me for piling on.
Here's my technique for figuring out where a new pistol is shooting first time out. It doesn't have to be a brand spanky new just out of the box pistol, just new to me.
First of all, I appreciate all of the learned pards who say you should shoot it just like you're going to shoot it in a match. I humbly disagree. If I want to know how intrinsicly accurate the pistol is, I'll shoot it two handed sitting at the bench with the my hands resting on sand bags. I understand the pistol will behave differently off sandbags than it will in my hands, but I want to know how intrinsicly accurate the pistol is, not how accurate I am. Waving around at the end of my arm while I'm standing will not show the pistol in it's best light. If I had a machine rest, I would take my first shots out of that and completely remove the human element.
I start out close in. Not at 25 yards. Reason is, if the gun is terrible, you want to know where the bullets are hitting. Farther away you need a bigger piece of paper to see where they're hitting. I usually start out right at SASS distances. About 25 feet or so. At my range we use cardboard target holders and they are big enough to hold six targets, 3 across the top and 3 across the bottom. I put up all 6 targets and butt them all up together so there are no gaps. That way I've covered the whole cardboard with fresh paper, and if any of the guns are really way off I'll be able to se where they're hitting.
I know I don't have to belabor everybody in how to pull a trigger, but just as a reminder I'll mention that rapid fire is not a good way to see how accurate an unknown pistol is. Find out where it's shooting first. Be sure you are pulling back with the pad of the trigger finger, not the crease behind the knuckle. Squeeze slow enough that you really don't know when it's going to go off to avoid flinching. After just a couple of groups like this, you'll have a good idea of where the pistol really shoots. Then you can repeat it at longer range if you want, or start shooting the way you really do in a match. But first you need to know where the gun is shooting all by itself.
