Made 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. Fed by an internal fixed magazine, the hammer, mounted in front of the grip, drives the rocket back onto a fixed firing pin, and is reset as the round shoots forward. 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 walnut, with a proper cutout on the left side for the magazine follower. Included with the pistol is a MBA box hand numbered to gun with shipping sleeve, and a factory ammunition box containing 22 (not a typo, twenty-two) rounds of scarce Gyrojet ammunition. This pistol is consecutively numbered with the Gyrojet pistol below.

Excellent, with 99% of the original anodized finish, with some dings around the front sight and muzzle and minor handling marks overall. Grips are excellent, with light pressure dents. Boxes are very good, with some wear and staining. Ammunition appears in good shape, with some darker areas on the jackets. Mechanically excellent.
