I agree with the GP100 recommendation
I'm going to chime in with the others who said not to overlook the GP100. I've gotten to shoot a few really sweet Smiths that were owned by friends, but a 4" GP100 is the only gun I've ever bought on impulse. I walked into the local gun shop and it was in the window, so I asked to dry fire it. That gun just spoke to me, and I told the owner, "Set it aside. I'll be back tomorrow with cash."
It's a great revolver. I've got two SP101s, one in .22lr and one in .357, and they're comparably stiffer (especially the .22lr), but that GP100 is just a peach.
