Do not add this to any "add everything" studios. There are four parts of the "sound animation": First, the slide locking back. Second, the clip ejecting. Third, a clip inserting Fourth, the slide releasing. There are three of each sound effect, and every time you click the green flag, it randomizes each sound effect in the sequence.
I recorded all of these myself with the "Turtle Beach Ear Force PX21" microphone.
