Recently I added some hardware to my gun cabinet to find that the 1/2 I was using for the rifles was too small so I removed the shelf I kept the handguns on and created these little organizational tools. The first is a trigger hanger. I designed it to fit my H&K VP9 which is a polymer frame so the trigger guard is wider than a metal frame so it fits both. The second is a magazine hanger for either a 30 rd banana clip or a 10 rd magazine for the AR-15 or M-16. Third is a hanger for the spare magazines for the H & K, it is a double stack 9mm so it would probably fit others. Gloc, CZ, ???. Inside diameter is 23 x 33 mm .
