I simply pocket carry with cargo pants (which I wear all the time). The thing I love about pocket carry is I can (very innocently) keep my hands in my pockets, with gun firmly in hand. I can draw from pocket very fast like this. I use guns with nothing that will snag on cloth as gun is drawn from pocket (i.e, sharp-edged rear sights, or slide).
With this holster you link to - you can't keep your hand in that pocket without looking suspicious.
Just MHO, of course..............
