Warning
I would highly suggest you learn on how to make SimpleSounds first.
The example provided here is the x16 pistol for which I used this post on https://www.gta5-mods.com. Since this is a pistol, I used the sns pistol as base template. Therefore the other sounds like reloading and such will be based on that. I have only replaced the PlayerFire entry which is the main firing sound.
If you just want to test this out. Run this resource (everything withing weaponAudio) and edit your weapon.meta of choice where you want to apply the sound. Find the <Audio> entry and replace it with audio_item_x16pistol.
