I don't wear belts anymore, just suspenders, so belt holsters would be out for me. Besides, I'd have to wear something that would conceal one. Don't like shoulder holsters. Carried in my jacket pocket for a little, very little, while - not easy or quick access in a vehicle. Joints too bad to use a ankle holster, almost impossible to reach one in a vehicle, and not quick access in any event. Wanted a concealed carry vest or jacket, but couldn't take the prices. So, cut up a pair of torn up jeans, cut wide around one hip pocket, and used wood glue to glue it to the top left inside of my denim vest. Worked perfect. My piece is completely out of sight if the vest flaps open, the color is close to the inside of the vest, it doesn't 'print', and is quick and easy in or out. I carry four spare, loaded, magazines in the left outside pocket, and plan on getting two more. Also just ordered a denim jacket, for coolish days when I want something a bit warmer than the vest, but don't want to wear something over the vest. It will get a pocket/holster also.
I had considered sewing it in, but that is a load of work, and would leave a thread pattern. I'd previously repaired holes and tears in a shirt using patches glued in with wood glue, Titebond II. I washed it to test it, and the patch was easily pulled up, so pushed it back, and put it in the drier. When I got it out it seemed as strong as when the glue first set. It has been washed I don't know how many times since, and is always good once it's gone thru the drier, as long as you don't mess with it when it comes out of the washer. For those that think wood glue is not strong enough, it is rated with a holding strength of something like 2,500 lbs per square inch.
