Ok, the Germans are the hands-down winners at developing innovative weapons, This, however, was not their finest moment.
Mythbusters tested it; it works if you define "works" as altering the flight path of the bullet. If you define "works" as a practical weapon, forget it.

use two of them and you can shoot the guy behind you...or yourself and the gun recoils FORWARD.

I have several rifles with the same problem. If I want to hit something, the best thing to do is throw it.

With exception of Road Runner cartoons, it'll still recoil backwards!

It'S called a RE-COIL by definition you cannot recoil from something, towards it.

How would you like to be the first guy that had to test it? That would be a little nerve wracking.

Better than being the first to test the Darwin pistol...

Since I had said use two so it shoots behind you, you'll get a recoil back from accelerating the bullet until it hits the curved part, then you'll get a force pulling away from you as it turns 180 to head backwards. At this point I don't know which would be more, you'd still have expanding gas during the turn so in theory it would still be accelerating.

Probably feel like a springer air rifle, back when you pull the trigger from the inertia of the piston then forward jump when the piston bottoms.
