Have a shooters belt from them incl. pistol holster and mag holders for pistols and rifles. That includes my TM MP7.
I've three on my belt, along with a pistol one and I think if I went higher than that it'd feel a tad heavy without adding shoulder straps. That aside they retain the mags well and I've not had one fall out despite much running, crawling and falling over.
Always been good at letting me know what's happening with my order and have replied to queries and issues quickly and efficiently.
I wouldn't hesitate to use them again.
