Different Fire sound of bullets.

[kalyubave92]

The sound made by guns differ when there is very less ammunition remaining in the clip. I have always noticed how my ak or usp sounds a bit high pitched when there are only 2-3 bullets remaining. Can someone confirm this and for how many bullets does this change? Is it only selected guns? What about AWP?

I’m fairly sure all guns do it as a heads up for running out of bullets

All guns make the sound, however I don't know the exact number of bullets it start
