Funny that so many mentioned the 1911, I never found them to be all that pleasant to shoot.
I have done some dremel work to my gen 4 g19 and it now fits my hands very well. Just doesn't have the feel of a steel gun.
Some revolvers bother my 2nd finger. The way the grips are and the weight of the gun pivots right on top of the 2nd finger. Might just be me with an old injury to that finger though. I think that's why I like the 3" 686, not as heavy out front
