I pocket carry my Taurus PT709 a lot. This weekend it was 12 to 15 hours a day and I never noticed it was there...and neither did anyone else. I frequently see people post that they can't pocket carry this pistol and I don't understand why not. Perhaps the difference is my custom-made 709 pocket holster.
My buddy (who does automotive paint and upholstery) made me this pocket holster below out of auto interior leather. It is thin and durable. I drew the design out on paper using the gun as a guide and I made it the same size and shape as my pants pockets. This thing rides perfect, stays put when drawing, doesn't print, and covers the trigger. All things you want a pocket holster to do. It essentially is a leather pocket liner cut to have good grip access.
Hopefully this will shed some light on how I pocket carry and perhaps give others creative ideas for aiding pocket carry.
