http://www.forgottenweapons.com The Gyrojet was the closest thing to a commercially successful rocket pistol, although not many were sold before the company went out of business. This is the 13mm pistol version (the most common type of Gyrojet), and fires a 180 grain rocket projectile. It was for sale - with 15 rounds of live ammunition - at the Rock Island Premier Auction in September. Hammer price on it was $5500. Theme music by Dylan Benson - http://dbproductioncompany.webs.com
