Never seen a Rhino, but had the chance to shoot (or try to take successive shots with) a Chiappa 1911-22 that a fella had at the range. The 22 was NOT anything approaching a decent-quality product. I am not impressed with Chiappa firearms.
I haven't shot one, but I have handled one. Decent ergo's... the design is to lower the barrel to be more in line with the wrist/grip. Less muzzle lift...more straight back push. Quicker second shots...you get the idea.
