Fairly new to handguns. I have a couple of autos (22lr, 9mm and 40 S&W) but have no knowledge when it comes to revolvers. Soooo, looking at the Rhino 40DS. Yea it's ugly and odd, but if I have to scratch an itch for a revolver might as well go with something that'll scratch the heck out of the itch. Anyway what is a 40DS? I have an FNX 40S&W any relation as far as S&W versus DS??
