Nope. Prototype from the detective takes the same ammo. See here: http://www.seriousgmod.com/threads/...ification-suggestion.20974/page-2#post-186501 That answer your question?
Can you kill if you saw him with an AK as primary, Deagle as secondary, then picks up pistol ammo? If I remember correctly you still can't kill for this, but there's no D weapons that take pistol ammo, so what's the reason, it really isn't evidence, sure you could say "ANYONE could pick up pistol ammo" but what if he was the only one around? By pistol ammo I mean 9mm.
This would absolutely be a valid kill by using common sense. You'd have have to have 100% certainty that all of the criteria is met. 1) Player has a Non 9mm pistol 2) Player has a Non 9mm primary 3) Player picks up 9mm You must be certain, that he is carrying a T weapon, or else you'll be killing on suspicion.
This would be the most difficult one to prove. Unless you actually saw him have out his non-9mm primary and then switch to a deagle or colt before picking up the ammo, you wouldn't be able to tell. Pistols no longer auto equip so at anytime during the round, I could purchase a pistol and, unless I pulled it out, you wouldn't know.
