Can't you shove another mag up the ass?
This mod wasn't made with the intention of cheating: This mod was made because there is alot of fun guns that no one uses due to low Total ammo.
If this mod doesn't work try installing Weapon Lib
What's Affected by this mod? (some guns here is stats may be lower in the game)
I didn't include pistol because [insert excuse] if you want more guns to this list harass me in the comments
