I have very limited experience with two of them, but still have my opinions.
First, let's eliminate the silly:
yes, it sounds like they are pretty awesome hand cannons with the recoil of a .22
Was this posted in jest? Because outside of it being a casual joke, it's not helpful. A Rhino isn't going to feel like a .22cal, even if you are launching target .38cal wadcutter ammo from it.
I have a buddy who has one, unfortunately... he doesn't live close to me. So I've only had one short session with it. It was all that's been said thus far-- the design radically reduces muzzle flip and make the recoil
FAR easier to manage. No doubt and no argument. The idea to radically lower the bore axis has outrageous merit. It's a phenomenal idea and it works. It does not eliminate recoil, for sure. It will still thump your hand and that won't ever go away, but it's far easier to shoot.
That cocking lever is an absolute bear to operate, it's as if they simply don't give you the leverage required to move the thing. Not a deal breaker for me so much; I much prefer to shoot revolvers double action. Of course, the double action is nothing to write home about, but I can deal with it. Suffice to say that my short range session with it was positive, and it was an interesting and enjoyable experience.
My run-in with the other one... not so much!
I tried a six-inch Rhino at the largest gun store in the area near my home and I asked the salesman if it was okay that I attempted a couple dry-fires and he not only said yes, he added that he hoped I would. And it
BROKE on the 3rd or 4th snap. Trigger stayed back, done for the day, and got itself a round trip ticket for warranty work.
I apologized profusely and admitted that I was embarrassed. The salesman wouldn't hear of it. -HE- was more embarrassed, and thanked me for my interest and then he admitted that he was certainly happier that it broke in the store, and not on the first range trip of a recent buyer. I had to agree.
I've seen, handled and manipulated the other guns that Chiappa makes and sells, and it's hard to review them without using the word "JUNK" in there somewhere. The Rhino doesn't feel like junk and doesn't appear to be shoddily built, but the other Chiappa guns sure do seem to have that reputation. Never played with their lever action rifle, but I've read a review that claimed it was pretty lousy, and that rifle ain't cheap at all.
I love the physics and idea behind the platform. It's long been a dream of mine that Chiappa tosses their cards in and the design gets SOLD to a better manufacturer. If Smith & Wesson or Ruger got the rights to this and built their own version of a bottom-chamber revolver, I'd skip past the horrendous looks and buy one simply to put it through it's paces.
If Chiappa is building it, I'm not buying unless I can find a used one for chump money. And I'm going to figure the cost of return shipping in before I pull out my wallet. At the prices these go for -NEW-, I wouldn't even consider buying one. No way, no how.
