The GP100 is a larger framed revolver than a model 19 (k-framed). The differences in frame between a gp100, a Smith L-frame and a Colt python are so close as to be moot.
Maybe you're really searching for something in the n-frame size chambered for 357. Perhaps a Smith Model 27 or 28?
I must be mixed up on my Smith model #'s because it was bigger than the gp100 for sure. I'm not so great at this revolver stuff yet, it's a whole new world to me! Pretty sure the 686 felt bigger to me as well, maybe the gp100 I had just had smaller grips or something. I'm pretty sure the one Smith I was looking at was a 19 though. I will look at the gp100 he has in his case and see the difference.
