I need help with a M*A*S*H* episode?

what is the episode were Frank has a gun and he walks in a room were the guys are playing cards and they tell him to put down the gun or something and Frank says 'Oh, what a bunch of hoo ha its not even loaded' and the gun goes off? I saw this episode one time but forgot the name of the episode and i love that scene.Please help!


I know exactly the scene you mean, but I am not sure what episode it's in. There is an episode called "The Gun" in Season 4 where Radar is accused of stealing a vintage gun that Frank really has, but I don't know if that's the episode where this happened.
