I was able to have a conversation with @
karmapolice this afternoon and here is what I think at this point:
I was able to overcome poor trigger control in the past shooting Glocks because I had developed my grip enough to mask it. That’s how I could lock in one presentation and bang out a 2.5 sec Bill Drill. About 50% would be clean and of course that’s the part I remember.
This go-round (beginning last October) I began to work hard on trigger control. This time I’m getting it right (I propose my success with my wife’s P239 DAO, in addition to the Glock and Beretta as evidence). The trick is I’ve changed holsters (OWB Bladetech style due to easy on/off during lunch breaks in work clothes), and changed guns (Beretta 92), so different grip, and different trigger. I’ve had the Beretta holster for about 2 weeks now, so aquiring grip and drawing with it are still fairly new.
Often my first hit is good (even if slow), and it’s the subsequent shots that go off the rails. My hypothesis is that I’m subconsciously defaulting to the grip and rip style that used to (sort of) work with the Glock, but doesn’t work with the Beretta because grip and recoil impulse are different (same thought about pre-ignition flinch to mitigate recoil as I’ve ingrained to do with the Glock).
The solution is probably to learn to prep and press the trigger more quickly while maintaining a clean press. Spread is mostly vertical, not lateral, so that’s good, but still grip could probably use some work as well.
In dryfire I can work with a low par to force me to get the gun out and get on the trigger quick, but watching the front sight to make sure the trigger breaks cleanly.
