SWEP.ReloadSound Not Working

[majorrr]

hello im currently making an swep and i cant see what is wrong, when i add a reload sound in the code:
SWEP.ReloadSound = "pistol_reload1.wav"
it does not play in game
here is the sound dir
Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\sound\pistol_reload1.wav
i dont know what is wrong can someone help me
also i added the fire sound just fine, its in the same directory

Try. While making a swep put down your sound in "ADDONFOLDER/sound/weapons/"
local ReloadSound = Sound( "weapons/sound.mp3" )
function SWEP:Reload()
self:EmitSound( ReloadSound )
end

ok so now there is no reload animation or sound

I am very new to lua but I was thinking when you hit a key in this case "r" it would play the sound but not with the animation but it syncs with the animation so it looks and sounds correct. Is there a way i could do this? is there an easier way? or did I mess up the directory
C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\lua\weapons\weapon_pistol_remastard\sound\weapons
