Gun Sounds in Movies

[Kinzer]

Why is it that in every movie, when ever some pulls out a gun, it's constantly making noises. Any character takes out a gun and it makes that chh-chk sound even though he is clearly not doing anything to the gun. He lowers the gun and it makes the sound again, points it at somebody, sets it down, looks at it...it's annoying. I mean are we supposed to think he is constantly uncocking and recocking it? It's just stupid. It's even worse when a gun is pulled and pointed at someones head. Seeing a firearm pointed at a persons face isn't enough, it need to making clicking noises. Just something that always bothered me.
