Hi all,
First, I'd like to thank everyone on this forum who provides such a wealth of experienced shooting knowledge. I have learned a lot from many of you. In fact, one or two posts from member Surf a while ago about grip technique and trigger control struck such a chord with me that it was like a light switch came on in my head, and my accuracy and recoil control improved quite a bit. Anyway, I'm what you'd call an educated responsible armed citizen, who shoots perhaps 400-500 rounds of 9mm per month (plus some .22LR), and I attend some IDPA practices now and then. I also try to dry fire maybe twice a week for about 15 minutes, I basically just shoot Glocks, my entire gun-owning life. I realize that diagnosing a problem in someone's shooting is very difficult over the Internet, but what the heck? We can give it a try.
This past weekend I was practicing with the G19 that I carry AIWB in a Dale Fricke ArchAngel. At 10 yards, slow fire singles as well as well-controlled pairs when I know I have a solid proper grip on the gun, I can basically keep them all in about a 3-inch circle centered in my POA. Though, I do have a slight bias toward the left with some vertical stringing when I don't concentrate as hard or when I start getting tired.
I noticed that when I practice drawing from my AIWB holster and fire, that I tend to accentuate my left impact bias and the vertical stringing gets a bit larger. In trying to self-diagnose the issue, I feel that its the grip I establish on the draw that is the main culprit, and perhaps that I'm going a bit faster than I should and not taking the time to see what I need to see. A few times after drawing and firing a single shot quickly and I see, for example, that the bullet impacted high-left, I look at my sights to see they are pointed just that, high-left. I tilt my head to align my eye with the sights and bingo, that's where the bullet went. It's almost like I need to work extra hard to align the sights on the draw, if that makes sense.
My grip technique is pretty standard: web of hand as high on the backstrap as possible, squeeze front and back straps with firing hand, palm of non-firing hand up against the open area of the frame, wrap non-firing fingers around the front proving side-to-side pressure, non-firing wrist is not overly "locked", just firm, chest muscles pressing sides of gun together like the "walnut", and arms are not locked straight out.
Again, like I said, I feel that my ability to establish the proper grip on the pistol on the draw may be the reason, but of course I'm open to listening to your feedback and suggestions. I definitely think I can do more dry work, working on my draw and establishing a solid proper grip. Thanks for any help you can provide.
