Impressive holding power - Hornady Magnetic Accessory Mounts

I am very impressed by the holding power of these magnets. I have 7 fully loaded Wilson Combat 45acp 10 rd extended mags with enough space in between for my fingers on the larger magnet. I have found use for the smaller one to keep 2 extra rifles from tipping or sliding around in the cabinet. They work well on a few 9mm pistols too. They come with that really strong 3M automotive double sided tape as well as the screw mounts. I really like the Hornady cabinet too. Need to get another one. Great stuff.
