Some thoughts on fit, and how a pistol feels, in the hand:
As P-F member HCM often reminds us, the way a pistol feels can LIE to us. Feeling good, in the hand, is not the same thing as a proper fit.
Then, my personal thing: There are handSguns, and there are handguns. Much emphasis is placed upon a weapon that fits, with a two-handed, thumbs-forward grip. I believe that real-world carry gun should/must work well when fired one-handed, because one cannot count upon having two hands available, during a sudden fight. With hand-held lights, dog leashes, and walking sticks/canes being such common things, in my life, and the occasional toddler grandson to deal with, I am going to presume that I will have only one hand available to fire a defensive handgun. (And, that is before I factor-in that my right hand is not aging well, and is losing the range of motion necessary to assume a proper thumb-forward support position, anyway.)
