First of all, the attachment for the primary weapon exsists on the player models.... What do all you guys saying about how hard it would be have to say about that! (you can view it in halflife model viewer)
Also, everyone seems to think there would have to be some MASSIVE change somewhere.... why? why would it need to take longer?! You do realise that frags etc never used to appear on the player and now they do! Theres no difference from 1.6 to Source with how frags work... why would the primary weapon have to change other than being purely asthetic?
