Advertising your gun, whether LE or a private citizen, is never a good idea...
You're definitely target #1 if things turn to crap...
Man with hand in pocket feel cocky all day.
Yes, these things do happen with pocket carry, as well as when carrying in a OWB holster, IWB holster, carrying a long gun with a sling, without a sling, putting a gun on the night stand, putting a gun in the safe, unloading a gun, loading a gun. Safety fail can happen, I don't know that it happens more with pocket carry than other types of carry, but to me, being aware of the responsibility of carrying a weapon, no matter how I'm carrying, is my first priority.
