Directing Pistol

[Spiritual Sausage]

I was reading Robert Silverberg's "Sunrise on Mercury" when it mentioned a tool that would fit well ingame.
It was a directionary pistol that would shoot a bullet out to send the user back.
I feel this would be good so that people lost in space wouldn't have to keep throwing shit and then losing it afterwards.
Should deal minor brute damage as it not meant to be used as a weapon.
