This is where I am too.
Having shot 20+ different handguns in steel challenge events over the last 2+ years, (from KelTec PF 9's to 455 Webley's) I have a really appreciation for, and I would say a need
for, a good firm if not hard grip. I am no TGO, but I agree that one can have a loosest of grip and hit just fine...ONCE...add speed and healthy grip is important.
