srsly, I wear scrubs at work, and jeans and a t-shirt outside of work, and I just use an IWB holster for my S & W Sigma 9mm. no one can see it, and I can get to it pretty quick.
my beretta isn't my carry pistol, and pretty much stays in the truck, or at home.
if/when I can afford it, I want to get a short 357 Mag revolver, and I could get an ankle hoster as well as an IWB.
the 'nades I keep in the truck
