Got mine and took it for a short walk yesterday. Fits a full size Glock in the "outside" zippered compartment. The compartment has Velcro sewn inside and it attaches to the velcro that is on the holster that is on my old fanny pack holster. After a little adjustment to the main strap it seemed to ride pretty good. The zippers seem fine and the thing has lots of room. Now I need to get a water bottle, any ideas on a decent one ?
