The Gyrojet pistol fired small rocket propelled bullets.The pistol was not very successful. I saw one for sale in a local shop a few months ago- they wanted about $3000 for it and ammo is near impossible to get for it.

Here you go the

HK G11

Complete with pictures, diagrams and movies.

And the pistol version

G11 PDW

Only on paper though from what I can tell they never actually made one.

I love brass and am NOT waiting for this to happen. How do we reload a case that doesn't exist. This is an idea whose time has not come.[&:]

I'm sure the Gyrojet ammo is a collector's item only these days! Once I worked one winter in a gun shop. We had one of those Gyrojet contraptions and the ammo for sale-noone was interested! To me, the thing's main failure was that at ranges under about 10 yards, the rocket-bullets had not yet attained enough velocity to damage an assailant. In other words, they were useless at the ranges where a pistol was most needed! And out where the little rockets were up to speed, they were pretty inaccurate.......
