I ordered an AE Nelson #114 quad magazine one of these 114-1 Quad Magazine Carrier for my P220, and have been using it for about a month. I requested it be made open top. I was very impressed with the overall quality of the product. The magazines will not fall out, but are still easy to access. Because of the orientation of the magazines it takes up less real estate on my belt. In fact, the carrier and my knife pouch take up the same space my old 2 magazine Safariland carrier did. I received it with spacers inside so the magazines were staggered like this... I decided that they stuck up too far, so I "fixed it," so they fit like this... The set up works great, but I ended up with an unforeseen problem. About once a week, someone asks about carrying four magazines. Which, makes me wonder how many other people notice, and don't say anything. A couple of regular folks no big deal, a 17 year old thug sizing me up I can understand too. The U.S. Marshall got me thinking about this though. Overall, I was very impressed with the product, but it certainly makes me think I might have to retire the P220, and go back to a high capacity duty gun.
