N82 covert magazine carrier
It only holds one magazine but god, is it comfortable!
I wonder if you got two, would it still be as comfortable...
Either way, I love how it vanishes into your pants but is there if you need it.
One of my training instructors mentioned how the off duty cop who engaged the spree killer in Ogden, Utah only had his subcompact pistol with like 6 rounds and no reloads... later he allegedly said "I'm carry more mags now".
