The Chiappa Rhino.
It made a bit of a splash at recent gun conventions. Firstly due to its striking and controversial appearance, and secondly because of its unique design features. Namely that its barrel is below the cylinder axis, and it fires from the bottom chamber of the cylinder. This reduces felt recoil and muzzle flip.
The internal lockwork to make this system work is pretty complicated. Thus the trigger is on the heavy side.
(more) Our friends over at The Truth About Guns reviewed the Rhino, and considered it full of potential, held back from being a true competitor to Smith&Wesson due to the heavy trigger, and the lack of clearly visible sights. The unknown factor is durability.
Gunsforsale reviewed it, and found that the excellent job of taming recoil more than compensated for the trigger. American Rifleman took a look at the Rhino and raised the issue of a lack of a track record for reliability in an otherwise positive review.
So far, I haven’t seen any reviews where the Rhino locked up (like Taurus revolvers sometimes do). But I do want more of a track record of use to judge the durability and reliability of the gun before I would consider buying it. And, part of me wonders what will happen when a Rhino kabooms. In a conventional revolver, the top chamber is what will get kaboomed, and the force & debris will be sent to the side and upward. The Rhino fires from the bottom chamber, which is very close to the shooter’s hands and has less metal between the chamber and your hands.
The Rhino is actually an updated version of the Mateba Autorevolver, by the same designer.
UPDATE by Crapgame:
Here’s a short video illustrating how little barrel rise you get with the Rhino:
Shelly Rae at GunNutsMedia put a Chiappa Rhino into the rental counter where she works. The verdict: heavy DA trigger and numerous misfires due to suspected light strikes. Hopefully there will be updates as the situation progresses.
