Excellent mag carrier

This is a great mag carrier and probably the only ones that I will be equipping going forward. Just the fact that they lay so much better than a vertical carrier is enough. The color was a perfect match to a preexisting kydex holster that I already owned. Great retention and adjustability. Get one, or more.

Good holster

The quality is good. The fit is good. Everything is good. I will be buying more from RC Holsters.

easy to conceal

I purchased this for my sig p365 as I was tired of the discomfort wearing a standard iwb holster. The horizontal position allows me to carry concealed by covering with an overshirt or sweatshirt. The holster looks good and is well built and conceals well and holds magazine tight.

Hellcat magazine

Holds my Hellcat magazine firmly and looks good too. The quality of the work and the edges are better than I imagined they would be. Great price for something this high quality.

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.
