This is some of my personal CSGO sound files you can use in PayDay 2 for better (IMO) sound. One of the things that make CSGO unique is the sounds that are used in the game. I added Deagle, AK47, AWP, Knife for now. Will add more soon, let me know which sounds you'd like.

You can also get configs for CSGO if you need it, will make some for PayDay 2 soon as well.
