I feel as if I have a substantial firing hand grip as far as height to bore, being seated in the webbing of my hand, etc. I just feel that I'm very critical of myself regarding support hand. I have not recorded myself shooting which might be the best medicine, BUT, I'm looking for tips or recommendations on how I know if I'd be on the right track regarding support-hand grip.
Mostly, my concern is that my support hand is allowing too much muzzle flip and that I may not be utilizing all the parts of the gun or frame to mitigate recoil. Right now I have a thumbs forward approach. Driving my thumb down into the safety does not feel right (but maybe I should just deal with it).
Any broad wisdom to offer me?
