Take the Smith & Wesson Model 19-2, a exhibition grade .357 magnum revolver which was licensed to the King by serial number on Nov 6, 1970. Elvis had the piece sent to Friedrick Wilhelm Heym Co. in Germany for a custom embellishment.

And the result was something quite spectacular: the little K-frame revolver was given the Midas touch with a relief leaf and scroll engraving, gold and silver inlaid borders, and five incredible raised gold North American game animals.

The staghorn grips have been elaborately engraved in a similar vine and scroll pattern and feature two engraved game animals of their own. Not a square inch of this gun was left undecorated.

The piece will becoming to auction at antique firearms specialist Rock Island with an unbroken line of provenance. Known as much for his generosity as his gyrating, Elvis gifted the piece to Vice President Spiro Agnew during a trip to Washington D.C.

Unfortunately for Agnew, he was only able to keep the presentation revolver for a short period of time before returning it as he was under investigation for corruption, which would eventually result in his resignation and other penalties.

Known for his great support of law enforcement, Elvis presented the piece to Sheriff Gene Barksdale after the sheriff had helped Elvis in the past.

At a later date, Sheriff Barksdale passed that Smith & Wesson Model 19 on to his nephew. From that nephew, this incredible collector firearm comes to Rock Island Auction Company in the same auction on May 5, 2017.

The second of Elvis' revolvers hitting the auction block is the Colt Python. As early as 1973 it was featured in Guns Magazine, so while it has been in the public eye for some time, it has not been available for public sale since Elvis himself bought it himself. Until now.

The piece is decorated in the same style as the Smith & Wesson Model 19-2, with the work again performed by Friedrick Wilhelm Heym Co. in Germany. This sumptuous snake gun was presented by Elvis to Richard Grob, the Director of Security and Operations for Elvis Presley Enterprises. Grob worked for Presley from 1967 until his death in 1977 and in that time became a close personal friend and confidant. He advised the King on many of his firearm purchases and frequently accompanied him to firing ranges.
