I like the hexagonal cylinder. Frankly I think it is a design aspect that should be used on other 6 shot revolvers. Makes it a little flatter, the smaller ones would be very concealable.
As for the chiappa revolver, I have heard less than great things about the trigger pull, but they shoot with hardly any muzzle jump at all shooting .357 magnum from a 2" barrel.
It looks ugly, but they have some forward thinking ideas, some of which probably could stand a bit more polishing.
