I've been working on WHO only (left hand) lately. This has always been frustrating for me and I've always been pretty good at just using high-left Kentucky windage and jerking the rounds low-right to where they're supposed to go. Not really a good way, but if it's stupid and it works...

I can call my shots, but DANG if I can't get my left trigger finger to do what it's supposed to.

I'll start freezing on the trigger or staging it. I can't get repeatable with the trigger control.

Trigger type really doesn't matter (doesn't matter in any of my handgun shooting).

Last time shooting I was thinking about this thread. 'All you gotta do is pull the trigger straight back and don't disrupt the sights.' Simple, but difficult.
