Thanks Kahrguy. I am aware of the velocity loss from a shorter barrel and like I stated in the first post I would treat this more like a 44 special anyway. Just like the Taurus Tracker I had the frame at the crane area looks a little small for much full bore mag load shooting. I just like the idea of a small sized 44 handgun without going to a charter arms.
I looked on the Rossi site and they don't even have this gun listed that I could find so I don't know if they even offer a 4" barreled version.
