Guns in space = cool.

But if they were to puncture part of the ISS, man, would they be in trouble. It's not like a plane, where if they start losing cabin pressure and oxygen they can descend. That baby is isolated, and losing a bunch of oxygen would be very, very bad.

...Am I the only person who thinks that a shooting range on the moon would be cool as hell?

Adam, a bullet wouldn't do any more damage to the station than a meteor puncture, and they patch those several times a year. The only real danger from the gun is if it's the crazy crewmember that gets hold of it first - but a crazy person has many other ways to kill off everyone in the station.

But the gun isn't on the station itself, it's in the survival kit for the Soyuz that stays docked to take the crew back to Earth in a crisis. The Soyuz would land by parachute in Kazhakistan (spelling?) if everything went well, or somewhere in Siberia, Mongolia, or the 'stans if the guidance was off. The survival kit is for after the landing. Cosmonauts have waited up to three days for pick-up, and often have to wait overnight. One crew found their capsule surrounded by a wolf pack. Besides scaring off wolves, a small-caliber pistol is a hunting weapon, a signalling device, and a fire-starter.
