Mag carrier

Excellent. Communication was over and above.


Quick delivery, nice fit for Sig P365 mag, like the optional clip styles for attaching to belts.

great mag holder

I use it to carry spare cz p10 mag. Works good, looks good and conceals easily. Fast shipping. Awesome.

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.
