Although the pistol is a secondary weapon, the use of which is either not relevant in most cases, or not effective, but this does not mean that you can ignore the spare ammunition for it.   

The POB pouch is designed for pistol magazines like Yarigin or Glock. The size of the pouch allows you to place a small multitool like Gerber inside.   

The flap closes with Velcro, the internal volume can change when the flap position changes.
