Anyone know where to find a "trick" inside the pants holster for glock 23? If you dont know what I mean by "trick", they make a holster for the 1911's that mounts under the pistol grip and has a thin strip of metal/carbon that clips to your pants. Glock has something similar but I can't find them anywhere. Rather than mounting under the grip, they mount to the back of the slide on Glock.
