Just a bassier sound.
Cause bass is life.
Bass is my tradition.
Anyway, here's a video comparison between vanilla (might be BaS) and modified one:
Youtube.com
Installation:
1) EXTREMELY IMPORTANT: **Make a backup of gamedata/configs/items/weapons/weapon_sounds*, you need this in case you want to uninstall this.
2) Use Mod Organizer 2 (recommended) or manually overwrite the gamedata folder with the contents in this .rar package.
Uninstall:
Untick in Mod Organizer 2 and remove
Or take these steps:
1) Take your backup of weapon_sounds and paste inside the weapons folder in "gamedata/configs/items/weapons/"
2) Remove the "deagle" folder in gamedata/sounds/weapons/
"Cause bass is life. Bass is my tradition."

I think it's worse than the original sound because now it's in mono which pretty much isolates the sound from the environment. Maybe you can do a stereo version which adds space to the gunshot.
What? This new engine plays stereo now?
That's good news to me.
I don't know anything about the sound handling of the engine but since there are stereo sounds (like the first gunshot sound in your video) it's possible.
