Gotta go with a Dual Gun primary for my blaster love, and how about some sort of knife/blade/claw secondary? Sure the guns speak for themselves, but with such prominate blaster secondaries like energy manipulation, why not have a close-range melee sec using a short blade?
And don't forget that guns can be used to fire other things than bullets? I'd love to bring my whole "mutant with the ability to channel energy through his custom guns" into reality...*sigh
