Fits 9mm, 40cal, 45acp Double Stack Magazines.
Glock19 magazines are the shortest you want to use in these pouches.
These pouches, come with just the right amount of "GAP" space in between the pouches for much improved indexing of magazines.
These DO NOT come with malice clips, or Esstac belt loops.
(Will not work for Glock26 or similer magazines they too short in height).
