The Model 773 Open Top Magazine Pouch is an innovative competition pouch design. It utilizes the same adjustable belt loop and rollers as the 771 but has a closed-in front area of the pouch so that it helps retain the magazine. The 773 is adjustable to any angle within a 90 range and the belt loop can also be ordered separately in two sizes: 1.5 in. (38 mm) and 2.25 in. (58 mm).
