Re-made the weapon.dat file to be more realistic, so far only ammo has been redone, and set the "Silenced 9mm Pistol" to have the same damage as the "9mm Pistol" because a silencer does NOT add more damage.
Will be doing alot more to the weapons.dat file in the future.
Just replace the weapon.dat file in the Data folder with this one, make a copy of the original weapons.dat file and name it "original_weapon.dat" as a backup.
