For those of you who have to wear your shirt tucked in at work, how do you carry? What kind of holster do you use? I've always carried using an IWB, but that won't work here. Hell, with the kind of work I do, even that doesn't work sometimes if the shirt is short enough. Let's just say a fellow employee spotted it at my last job and I have a sneaking suspicion it's the reason I was fired shortly after. I'd like to avoid that again.
