Still kinda want one...

The Rhino has apparently cleared customs and should be hitting dealer's cases soon.

I probably would go with the 4" version personally, although I'm not sure about the holes in the overlug(?).  Still, it appeals to me for the same reason I own a Nagant Revolver.  It's different, kind of weird really, and I like that in a gun.  (The Nagant still gets massive bonus points for looking quite steampunky right out of the box though, the Rhino, like the Mateba before it, definitely has a more Sci Fi feel.)
