My primary weapon would have to be a Kitana... A nice sharp black blade, I'm thinking Ichigo on this one... ((just because it looks pretty awesome.))
My secondary weapon would be two concealed hand guns... Not just one... but two... one for each hand! ha ha! ^_^ I'm a pretty great shot... And I'm thinking Gun Kata ((the term coined from the gun martial arts in the film Equilibrium)) would be pretty handy when dealing with a lot of enemies.
My emergency weapon... Well, to be honest, I believe that overkill is perfectly okay~ Explosives of some kind... That I can plant, run, and then detonate when I'm far enough away. Whoot!
