I need to be discreet, and use a pocket holster with an anti-print panel for my LCP from Pocket Holsters.
Sometimes, if the draw was not done quite correctly, the holster would come out of the pocket with the pistol. Obviously, not a good situation! This was especially true of suit pants, with their thinner and more "slippery" material.
My solution was to put a piece of duct tape on the back of the anti-print panel, and add a piece of double-sided tape on top of that. It does a very nice job of keeping the holster firmly planted inside the pocket. I change the tape every few days, when it loses its tackiness.
Just a suggestion, if anyone else has experienced this issue.
