if you think that looks like one is armed, try the guy here:

another option is one of them outdoors/photographers vests. now your talking pockets

mostly i see this as a issue of culture/social vs practical.

same really as with wearing bluetooth handsfree on the street (but if they are designed as oversized skullcandy headsets it would be fine, go fig)...

and yes, i do own and use one of those urbantool basicholsters.
