Right, if anyone has ever looked, in the sdk files there are (I think) five sdk weapons.
Sdk_Shotgun
Sdk_pistol
Sdk_MP5
Sdk_Melee
Sdk_Grenade
Now, one of these works, and is included if you do a multiplayer template mod. The pistol fires, does damage, but the view model is off center.
Shotgun is included, but it's ammo is invalid, and its view model is again off center (Both Cs:s view models)
I can't find a way to load the others in game, impulse 101 gives these two and the hl2 weps, messing up the inventory system)
Has anyone used them? they aren't even on the wiki...
