Interesting. For me I have small hands so I find exactly the opposite. Shooting a larger pistol requires my hands to be more open and I have less strength in my grip that way. When I can get my hands around something like a P365 or a G43, I feel like I could literally break the frame in my hands if I wanted to, and my hands don't get near as tired and I have a much stronger grip on the gun. ....but Im a puss.More surface area on the hand. The wider frame spreads out the impact of the recoil.
