The problem with pocket carry is security.
For example I can’t count the number of times my cell phone has fallen out of a pocket.
I have conceal carried for 38 years and have never had a handgun fall out of a holster.
Now if you are not very active, don’t run, jump, roll around on the ground, etc, pocket carry might work fine.
For me, not so much.
In the winter I will move the gun outward so to speak so I am only living on garment to draw. Again, it’s NC, with mild winters so that usually means a vest or a short coat or jacket. IWB or OWB under the vest, jacket or coat, works fine.
Back home in SD with a long parka, a different approach was required.
Pocket carry doesn't necessary imply no holster. In winter am pocket carrying G23 in a pocket holster. Granted it is a heavily modified pocket.
