I get this. I really tried to study up on grip and stance and found myself trying up different stuff each time I was at the range. I was overthinking it too much. I'm not denying there is a "best" grip or stance, but I think once a person starts shooting a lot, if you are training and not just burning ammo, you'll change towards what works for you. I started off shooting pistols like WW2 GI's and have mostly broke that and moved towards some sort of a modern stance with a thumbs forward grip. Same thing with sight picture, I was geeking out over a millimeter here and there. Last time I shot, I don't really remember my sight picture. I just fired once the gun settled down and it was "good enough" and I did better than when I was over analyzing it. Unfortunately I can attest to skills degrading pretty rapidly once you aren't shooting regularly also. I will add, you all may be better shooters than me and I am sure I would benefit from professional handgun training classes where they may indeed tell me my stance and grip are all ate up.
