Anybody know the patents or limitations on the Rhino design?

Id really like one chrome with wood grips if they made one in 44 mag.

It has a lot to do with the type of aluminum alloy used to make the receiver and the frame of the Rhino, as well as the entire process method Chiappa chose to manufacturer the revolver.

Chiappa produces the Rhino with a particular alloy, Ergal™, a trade name for 7075-T651 HCS. The Coltalloy™ used by Colt for the Lightweight Commander is also produced with 7075, although with a slight variation in their metallurgy recipe to make their own proprietary alloy. Similarly, S&W has a trade secret recipe for 7075 aluminum with the addition of scandium. The cost of this alloy material is not cheap, being the highest tensile strength aluminum available to manufacturers. The high-price of the firearms for making Colt's Coltalloy, S&W's scandium, and Chiappa's Ergal (or basically 7075) simply reflects the high-production costs.

The other factor in being expensive is the manufacturing process specific to Chiappa when it comes to the Rhino revolver. The frame and receiver of the Rhino are made through CNC, unlike S&W's method of quality forging or Ruger's durable casting of heavy parts. While CNC has the advantage of creating more easily the small and complicated parts necessary to actuate the internal hammer of the Rhino, it costs a lot more because the wasted excess shavings from the single block billet of Ergal alloy after being CNC'd can only be sold for scrap metal.

US Patent #: 7523578
Inventor: Emilio Ghisoni
Date Issued: April 28, 2009
Abstract: A revolver that has firing means arranged so as to substantially raise the resting point of the middle finger of the hand on the handle

US design patents are protected for a term of 14 years from the date issued, so that would make Ghisoni's patent of the Rhino design exclusive to Chiappa until 2023.

Thanks. I'm fascinated by this design and have read lots about Ghisoni and MATEBA but wasn't sure how long this design was Chiappas. I appreciate your help.

Remember when Taurus introduced the Judge? Despite having critical reception and being different than the established revolver, the popularity in sales caused S&W to follow suit with an higher quality copy known as the Governor. Notably, this scandium framed version by S&W certainly costs a pretty penny for a snubnosed alloy revolver, in fact just as costly as a Chiappa Rhino.

If S&W ever went through with making their own version of the Rhino design, we won't see it for another decade until the patent expires (if by then Chiappa is still in business or if there is still any interest in the Rhino). A forged Rhino with a scandium frame would produce a spectacularly high quality revolver, a $2000 price tag might not be far off.

Another thing to note is that the CNC process does not produce the same perceived quality as say, the forged process used by S&W. While traditional forging produces tightly packed surfaces, due to the method of CNC cutting away at a single block of metal, the surface and edges are sharper and less compact than forging. That's why in the hand, the Rhino lacks the "dehorned" and smooth deluxeness so to speak seen in a S&W.

Edit: You bring up a great point Windlestick, I don't know if Chiappa actually paid for a contracted amount of time for licensed exclusivity of the Rhino's patent, or if they are now the sole proprietor of the design now that Ghisoni has passed away.

The Rhino might be more popular if they focused on more functional designs. For most hunters a 6" barrel just doesn't cut it. Then 357 is the largest caliber they appear to produce. The rhino would be a tough sell in my neck of the woods or any part of the woods for that matter. The design would be great for large bear and moose but they don't build a gun that anyone would hunt with.

Check that. You will be second in line. I already pitched my tent by the front door.

I haven't dont a lot of research on them. What's the average price? How much did you pay if you don't mind me asking op?

I've heard the 357 mag shoots with the recoil of a 9mm. I don't have much experience with revolvers other than my friends s&w mp snubby. It doesn't bother me at all to shoot. I would just like smooth recoil for faster follow up shots.
