You can't see it in the photo, but I am wearing a P90 drop leg mag pouch, which holds those rediculously large mags. I have used the same vest for a while, and it the "cheaper" kind, which only holds M16/M4 mags, which was fine because that is my primary gun. I also have invested in the first factory box mag, which allows me to use a M16/M4 mag, and hopper with the P90, so the M16 mags still hang around on my vest. I will probably swap vests soon as well, since I have a MOLLE II FSBE replica coming in the mail shortly, more pics when that gets here.
