Figured I'd update - I took a dremel to the trigger guard, did the trigger-undercut-whatever to it, much better AND my middle finger does not hurt after shooting it.
I'm still way better with my 1911s, but when I look at the results with the Glock, it strikes me as though that's what I told it to do. Seems that the sharp edge of the trigger guard kept me from being at least a little consistent on the grip.
Thanks for the suggestions!
I have also heard the glock was designed to have your trigger finger hold the trigger in the crease of the bend and not on the pad. I have seen this make difference when you also take up the first stage and stop at the sear. Definitely different trigger systems.
A toughening of your mental hyde is your best defense.
Take it to a bowling pin match. This will force you to shoot accurately, and quickly. You're body will figure out what you need to do, then you don't have to try and figure it out in your head first.
