Mag Pouch, MPX, Triple, Open, Black is rated 3.5 out of 5 by 4 .

Rated 4 out of 5 by Gerst87 from Perfect for 30 round mags I have been using this to store, transport, and wear my mpx mags at the range. They fit in easily, and also accommodates the 30 round magazines with no difficulty. The only improvement I could see would be to have a molle attachment rather than velcro backs, as most carry bags and vests utilize molle instead of velcro backs, such as these have. Otherwise, great product and I expect nothing less from Sig.

Rated 1 out of 5 by ScoutPilot from The pouch is great Please put a molle strap setup on the back or at minimum a belt loop for retention. 3-30 round mags won’t withstand Velcro. Thank you!

Rated 5 out of 5 by Roya from MPX pouches I bought three of the MPX pouches a month ago and I give them a big thumbs up. They allow me to organize the mags in my backpack without shifting.
