Very interesting post and comments. I am tall and skinny and have never been able to shoot well with a straight grip; I just don't feel like I'm in control of the gun. My fingers are long and I have no problem with switching triggers on a DT gun with a pistol grip, so that is the setup I prefer. That makes it hard for me to find a modern sxs gun that I really like.
I was taught to shoot with normal grip pressure and have always avoided trying to hold on tightly to the gun. In fact, I don't think a really tight grip works well for any sort of athletic endeavor, whether it's golf, baseball, basketball, or shooting. I hold the forend when shooting a turkey, but I keep my left arm straight and grip the barrels when using a sxs in wing shooting.
But take my ideas with a grain of salt; Ky Jon is talking about a level of shooting with which I am not familiar.
