nice mag holster

I like the mag holster. fits well and seems quality made.
Only problem I had is the wide clip's holes don't match up on the holster so I can't use it, but I prefer the slim clip anyway.

Thanks for your review. To install the wide clip you will need to install at an angle. Place the first post at the top of the channel and the other post at the bottom of the opposite channel. Install the first screw and start the screw into the post but do not tighten. Then install the opposite screw in the same manner. Once both screws have been started but not tightened you can move the clip into a straight position or to your desired angle. Once in place tighten both screws all the way.

If you have any questions please reach out to us from our contact page.

This holster rocks

I bought two of these holsters, one for my P365 and the other for my P320. When they arrived I was impressed with the quality and attention to detail. The fit is excellent on both the P320 and the P365 version and the holster stays put on your belt. Mags go in and out smoothly and the firmness is adjustable with a phillips screwdriver. ave inferior products.


I was so tired of lugging this huge thing in my pants, its always so bulky and cumbersome, bulges in the pants and just slightly more difficult to conceal. So I started searching for a smaller one and came across this mag pouch, my girlfriend even loves it compared to larger bulkier ones. I was looking for the smallest minimalist mag pouch that I could find that actually enclosed the entire pouch, didn't rely on a magnet or small clip to keep the magazine secure. This thing is great I wish more companies made them this small. I compared this mag pouch to some other brands that are supposed to be top of the line and they are all just so bulky in comparison. this thing works with less kydex involved. other companies really need to get on board with this type of design. It fits very comfortably IWB and I hardly know its there. the magazine feels secure although a little lose for my liking but secure enough that it stays on and doesn't fall out when I move around. the RC three hole clip is a perfect companion with it as well and goes well with my raven concealment vanguard. id like to get the minimalist holster through reactive concealment but it appears they don't make it for the M&P Shield. but I will be purchasing more of these deep cover concealment mag pouches for my other firearms.
