Solid information! As I'm sitting at my desk this morning I'm using a blue gun to reproduce my grip and unless I'm jaded by what you've written I am using a c clamp grip. I tried the two exercises you mentioned and sure as shit with more finger tip pressure the trigger finger tip wants to curl in. In my range notes I'm making an entry to pay attention to this to be sure I really am using the c clamp. It's amazing how simple and how complex your grip is. I find it also amazing within your grip how many things you subconsciously. I will do some one handed dry practice as you mentioned. Thanks for the feedback. Feel free to ad any further info. I feel like I'm on the edge of figuring this thing out.
