This is the schtick to fight with a wide variety of guns.
You like your weapons cool and fresh when in action. You like to pick the right weapon for each job. You like to surprise opponents by drawing new, hidden guns in the middle of the fight. You like to shoot loads of different guns.
The first time you use a particular gun in a particular fight you get a +3 bonus to its Action Value. Especially if you can keep up an amusing banter about the advantages of each.
This is something of an opposite to SignatureGun, though it can be cumulative with that schtick. It combines very well with Bag Full of Guns and Fast Draw.
