Great Mag Holder

Very pleased with Reactive's horizontal mag holder. Like much better than traditional vertical mag pouch. Really like the clip. Works great for self defense training providing quick access to second clip. Will definitely purchase from Reactive again.

Fantastic product

I’ve been using daily for a few weeks now, and I’m tickled pink! Great product, great quality, great fit, very comfortable and built to my specs and delivered within a couple of weeks. I would highly recommend if your looking to carry an extra magazine.

fast delivery with great communication. Product as described.

I've tried them all! Love this one

I was tired of my standard vertical holster poking me in the side when I sit in my truck. I found myself taking the magazine off when in the truck and then forgetting to put it on when getting out of the truck. Decided to try a pocket carry, the one with the magnets. Pocket carry was comfortable but 50% of the time the pocket holster would come out with the magazine. Magnets were too strong I guess. After a few months of just putting it in my pocket loose, I decided to look for a horizontal carrier. Saw many on Ebay but they looked cheap and flimsy. I saw these guys on Ebay and decided to check them out. Reactive had good reviews everywhere so I decided to give them a try. The Reactive holster is a high quality holster and not only holds the mags tightly but it is comfortable too. Now when I'm in my truck I just need to slide the holster back a bit and I don't even notice it being on and when I leave the truck it is always with me. Great job and great holster!

Quality product

I had been looking for a quality magazine holder to carry along the waistband. After buying a few failures off Ebay and another site, I came across this holder and it looked to be a much better quality. Well, It definitely is a higher quality and the fit of the magazine in the holder is superb. Came packaged well and I knew what it was when it arrived. Great company and a great magazine holder too.

Nice holster

This is a nice holster that seems well made and durable. Fits multiple guns I have and is balanced well.
