uuuuuuuuuuuuuuuuhhhhhhhhhhhhhhh..........Oh yeah...the question. I was too cheap to buy one so I made my own. I have some back problems and had an old craftsman back brace I wasn't using. So I cut the shoulder straps off it and removed some of the plastic inserts so it wasn't so rigid(the ones I left alone are directly behind the pistol to ensure it doesn't bend behind the trigger or something). I turned it upside down(for some reason it fit my body better this way), added fabric store diy chrome snaps in two areas to keep the elastic tight and keep the pistol from falling through(those snaps are reinforced with superglue inside and out and do not function as snaps anymore, more like a rivet now). It has double velcro closures on the ends and the wide elastic band streches over everything and secures with velcro too. Very secure and will also hold many extra mags if needed, sometimes I even tuck my wallet and keys in it if I don't have pockets. It allows me to carry while in shorts or pants that my belt and holsters won't work on and is very stealth, no printing when bending or reaching etc. Works great for roadtrips too because it's right there in the front and the seatbelt isn't in the way of it. Works with revolvers and auto pistols big and small, they have never moved from where I put them. BTW, I'd carry anything but a glock in a bellyband, I like my groin area too much.
