If I ever get Airsoft weapons, they shall be the following:
FN P90. WITH THE DAMNED REFLEX SIGHT. Fricking triple-rail is fugly.
HK MP7. Sure, it's ugly, but if you stick the reticle you see in HL2 on it and pull the forward grip out, it loos pretty cool.
HK USP Match or Tactical.
Beretta 92.
I'll probably use the gas ones, they're the cheapest.
