Listen you do NOT need to do any of that bs above. You simply go into your addons, darkrpmodification, and goto lua, darkrp_modules. From there go into weapon settings you can change the damage on any gun as long as you copy the name of it through the q menu.
RE: Any way to change M9K Weapons damage stats on my DarkRP server?
Yes you just have to do modify the shared.lua that u can find in any weapon and u can edit stats there or use dwep that is an addon that has a gui to modify stats of weapons ingame
