Well, I fixed a weapons pack and made it a little bit more realistic, and added some sounds that were missing, and overall made it better. This pack contains:
All CS:S weapons with realistic effects
(sorry guys, doesn't blow down doors with a shotgun)

An Administrative Weapon,

(Controls for administrative weapon
Left-Click = Tight burst of thousands of shotgun bullets doing massive damage - Right click = Fire an explosive AWP round with a powerful shock wave dealing extra damage.)

And the best weapon, a C4, with very nice effects.
NOTE!: The explosion effects of this C4 will replace any other explosions of any other C4s that people have made, that you have in your addons folder!


Other note!: Sorry, slight mistake. The SG552 Sniper weapon was accidentally mis-named. I mixed it up with the SG550 Rifle. So the one saying 'Sniper' is actually the rifle. My bad! D:

Here is the fix for the missing Mac 10 and the mixed up rifles: http://www.garrysmod.org/downloads/?a=view&id=93727
