My Uncle passed away a couple weeks back and left me all of his firearms. Most of them are pretty common but this revolver I haven't seen before. I know it is a S&W in 357mag but im not sure of the model. It also has some sort of aftermarket sight and something under the barrel I have no idea what is it. I have included pics of every marking you can see on the frame/barrel. Thanks for any info you have.
