Handgun-
My most often concealed carry gun is my Glock 19C (Trijicon tritium night-sights, LW extended mag release, LW extended slide lock, custom slide cover plate, Scherer 3.5lb trigger connector, 2x 15rd mags w/ Cor-Bon +p 115gr JHP). If I'm taking one single handgun, that's the one. *If I get 2 then I want my trusty 1911*

Knife-
Swamp Rat Camp Tramp - without hesitation.

Caveat-
Always in my truck is my Kel-Tec Sub-2000. It is a folding 9mm carbine that shares mags with my Glock and has 5x 33rd mags stowed with it. This scenario is 'urban adventure', and this carbine is never far from me during my daily adventure.
