You'll get a lot of info here from some very knowledgable people, but I'll offer you my thoughts on the matter. If I had to do it all over again I would start with a S&W 629 Classic with a 6 1/2 inch barrel. If I could find the "DX" version, I would pick that one. Excellent single action trigger out of the box. Double action can be lightened with a simple spring swap. They are already drilled and tapped if you want to mount a scope. They will handle any standard loaded ammo which will be adequate for most animals. They are beautiful, well balanced, and are quite addicting! Just remember I said I would start with that one, but there will be more! Welcome aboard!
