Safari land's model 773 Competition magazine pouch is an improved design. Utilizes the same adjustable belt loop and rollers as the 771. The front area is closed to help retain the magazine. There is also a built-up channel for clearance of the tip of the bullet during the draw. Note: Order this magazine holder by which hand you shoot with. Right hand shooters wear the pouch on the left side and reload with the left hand. The opening faces to the rear and the bullets in the magazine face forward, for both right and left hand shooters.
