I will tell you what. I *love* getting on a plane full of soldiers or marines. Even when they're in civies you can always tell. They make me feel very safe.
The new vests and jackets there have an interesting new addition: Big velcro patches mounted inside the pockets, suitable for accepting some of the velcro-backed holsters. Which, I happen to have.
It is amazing, how you can have even a fairly large frame auto or revolver in one of the big oversize pockets and it simply doesn't show at all on the outside. I've tried it with my Kimber .45 and it doesn't show at all. It doesn't even hang all wrong with the weight in it.
I don't carry very often. But it is nice to be able to.
