Pocket carry in cargo pants/shorts does have some benefits, especially when driving/riding in a vehicle or any time you are sitting. It does put your defensive weapon in a location easier to reach in those instances. The larger and lower cargo pockets also allow for a larger and heavier gun(My Mak works great in a cargo pocket, but is too big for a hip pocket). Of course, when standing it's harder to reach the lower pockets.I'm partial to the pseudo-military style cargo shorts (helps to mitigate my long skinny legs ). I carry sunglasses, cell phone, etc down there in those big pockets.
I was thinking the other day that a small firearm would ride quite nicely down there. It seems that it would not be too obvious to the casual observer and would be reasonably secure and accessible.
The only downside that I see is that the gun would move around and could therefore not be in a consistent position for a safe draw.
Take it out and put it in my dash compartment.
