Aethal Universal IWB Holster for Concealed Carry | Inside The Waistband Holster | Tactical Pistol Mag Pouch | Magazine Holster (Mag Pouch)

I was skeptical at first but the magazine holsters work better than expected, even fully loaded magazines won't fall out when training

Comfortable and Cheap. Get what you pay for. Mag slides out easy, but if you aren't doing back flips, you should be ok.

Excellent very fast shipping

I use for my M&P Shield mag. It's comfortable but just as I read in other reviews, the mag does sink deep. However, when wearing IWB it is snug enough to pull up just slightly and stays in place well. When I remove from wearing, the mag is loose enough to fall out if not attentive to how it's held.
