I have given up carrying small pistols and now carry a glock 22 owb in a bladetech total eclipse on my side. I can sit, stand, walk, run, and buy properly fitting pants for the times when I'm not carrying. My pistol is completely concealed in a t shirt and jeans. I've never carried on my back, doubt I will, but I've always wondered how comfortable it is to sit in a restaurant or in a car with it back there? My draw gets to feeling awkward the further back I slide my holster so it always ends up just behind my front pant pocket which also conceals the grip print that comes with a full size doublestack pistol.
