I have recently started pocket carrying just because it is more convenient than putting on an IWB hybrid holster.
The drawback is that there is no way I could draw while belted into my car, whereas I can draw when IWB carrying at the 4 o’clock position.
It’s always a compromise between convenience, capacity, and speed of draw. I’m just a ccw civilian, so my priorities are on the first one.
Which is why I leave it somewhat hidden on the console while driving.
Drawing from right front pocket while seat-belted in and driving is easier if the pistol is repositioned every time the buckle is latched;
partially draw the pocket pistol with it’s holster to the top of the pocket.
Just enough to hook a few fingers around the grip, not enough for a full firing grip. Avoid the trigger.
YMMV, practice each and every time you sit in your car.
Get pants with cargo pockets.
