I'm wondering what kind of holster people use for concealed carry while wearing a flight suit. The squadron issued me a cheap nylon shoulder holster but it's not comfortable in any way. I noticed a lot of guys have bought their own shoulder holsters to wear under the bag. I've looked at the Galco Jackass system, which I like because its modular, so I can get different holster components for my personal pistols and swap them out. So what do you guys use? What features should I look for?
