In your game, what kind of gear do you carry in and out of combat? It is generally seen as bad form to carry flame throwers and meltas in a business negotiation, while at the same time such bulky weapons can also be bad if you are trying to sneak into a cultist's hide out. Buuuuuut at the same time, such weapons are invaluable for when the stuff really hits the fan. So, where do you sit?
For example, in the last game I played in, when ready for trouble my Psyker carried 2 autopistols in concealed holsters with 4 extra mags, a compact laspistol, a monosword, his knife and psyfocus, good flack armor with a helmet with poor auspex, photovisor and infragoggles installed.
Outside of combat the weapons were much the same, (unless he REALLY needed to go incogneto) with the compact laspistol and monosword being carried openly and the autos hidden. The armor was traded in for a light flack coat designed to look like a duster, and photocontacts hidden under goggles.
