I ran across some great images of the famous Gyrojet pistol test and used by some SOG recon troops in the Vietnam war. Even being used by MOH recipient George K. Sisler when he was killed in action.

While you can’t see his face in the pic above, the soldier holding the pistol is Franklin D. Miller, another SOG MOH recipient. Rumor mill suggest it is the same one carried by Sisler and recovered by Miller on the body recovery mission.
