About a year ago I decided I would get with the times and pick up a full-sized duty guns for local matches and informal competition.
I bought a P320 to try and the first time out I shot so badly I thought I was having a stroke until I put a magazine through my STI on paper. The trigger wasn't terrible in the SIG and other people shoot it reasonably well, but not me.
So I shot everything I could lay hands on and tried endless variations of grip and trigger finger placement and manage to occasionally shoot half well. It doesn't help that I have ridiculously oversized hands and could easily pull a trigger where some pistol's trigger guards are located. No handgun is comfortable to me.
The problem seems to be that the grip I am forced to take makes my grip inconsistent and bullet impact erratic. My best results come by maintaining a death grip despite tremors that disrupt my sight alignment. The consistent grip pressure seems to be critical in this type of gun.
Further, I find that the lighter constructed and more flexible a plastic frame is, the worse I am apt to shoot it. The aforementioned SIG being among chief offenders.
I am beginning to to think that I would be better off sticking with my larger frame revolvers and 1911's that minimize my awkward grip, trigger control faults and bad habits. I would to, as it would save much time, money and frustation.
On the other hand, I think I would be a better shooter overall if I could master the art of combat tupperware. In addition, I have a secondary goal of using a moden, size effective pistol as a carry gun.
I realize that most shooters these days transition the other directions and (what a revelation that must be) and there can't be too many dinosaurs like me left, but I'd be grateful for any advice that might help.
