Rather than buying the gun again, you should have the ability to get it fixed in playerbought shops. The shops would have to get material + "the skill" to repair a certain weapon. The more expensive the weapon, logically, the more expensive to repair it. If the player ignores repairing, THEN the gun will break and they have to buy a new one. This seems more fair.

Just another suggestion but what about gun tweaking? Custom ammo? For example some terrorist party might want stronger ammo for their ak47 because they're raving idiots and stronger ammo should = gun lasts less. This'll put the "fixed guns" solution in use as well.

Just a thought.
