If you got one of the first gen Rhino's they did not come with fibre optic sights and all came with the small wooden grip that was initially meant for the stubby 2" CCW marketed version.
Gen 2 came with FO sights and a better trigger (Not as gritty double action) and a longer laminate grip w/o finger grooves was available
I cannot recall if it is Gen 2 or Gen 3 that introduced moon-clips for 9mm & .40
That Charging Rhino has a very light, smooth double action and I was warned by Reno Chiappa that it does require soft primers due to the lighter hammer springs.
It cycled flawlessly when I looked at it.
I do have a Gen 1 Rhino 50DS, upgraded with FO and a longer grip and do like it. (Ghost made a holster for it as well that was IDPA compliant).
