Manufactured between 1962 and 1970, the Gyrojet pistol was intended to replace the standard powder filled cartridges with a super high velocity "rocket" type cartridge. In place of a traditional cartridge, it instead fires a self contained spin stabilized solid fuel rocket, removing the need for a strong breech or precise gas sealing. A sliding action cover takes the place of a traditional slide and is ported to direct the escaping gas to the sides, away from the shooter. The grips are smooth simulated black mother of pearl with a proper cutout on the left side for the magazine follower. Included with the pistol is a MBA case with a Robert Goddard medallion, fifteen rounds of ammunition and a grouping of related documents including an unsigned certificate of purchase.

Excellent, with 98% of the original finish, showing some light handling marks overall and a dark patina in the lower areas. Grips are excellent with light handling marks and the case shows some minor scuffs and dings. Mechanically excellent.
