Exactly!
G makes a great point. You do not need to walk around like Robo-Cop or Tactical Ted.
If the wind blows your jacket open or you bend over to pick up an item, so be it.
As a teen, I always thought one of the reasons actor Don Johnson(Det Sgt Sonny Crockett, NBC's Miami Vice
www.imfdb.org ) wore a horizontal type leather shoulder holster was so that it would conceal better when his character(a "undercover" vice detective) could open boxes or cases w/o his huge .45acp showing.
Brown or natural leather made sense too because it breathes & wouldn't have dye bleed or stain clothes in the humid, hot Miami climate like black leather.
