How would a hand gun behave (fire) in space?

I'm thinking both in a "space station" setting (which would fire but what would be the results because of the lack of gravity?) and in "no oxygen" setting (what would happen, would it fizzle or fire, and with the lack of gravity, what would happen?)

Nitric Acid (main ingredient of gunpowder) contains oxygen - the casing of the bullet would also have air sealed inside it from pressing, so it would still fire. With the lack of gravity & friction - when you fire the gun, the bullet would fire forward, you would fire backwards.
