well I went with a detachable mag 870 for our 3 gun (light) league, which left me with a problem. How to carry the friggin mags? After thinking about it some I figured I would try to make my own holster for it. I epoxied the belt clip to the back because, well I didn’t really have a good way to mold a spot for the screw plate. No press, just hand molding over the mag. I was surprised how easy it went. It isn’t going to win best in show but, it should work for what I need it for.
