This is a bad idea on so many levels:
Among other obvious failures he demonstrates in the video, it seems like a really good way to Tex Grebner yourself. I don’t know what people’s obsession with pocket carry is in the first place. You can get a really decent holster for under $40, carry a proper defense caliber pistol in it, stop bad guys AND not have to worry about ventilating your junk. Don’t even get me started on pea shooters like that for primary EDC.
