Magazine retention systems

A magazine retention system, comprising:

• a pouch defining a pouch interior and configured to receive an ammunition magazine in the pouch interior, the pouch including:
• sidewalls defining a pouch opening through which the ammunition magazine may be selectively placed within the pouch interior;
• and
• a floor coupled to the sidewalls opposite the pouch opening and cooperating with the sidewalls to define the pouch interior;
• an anchor coupled to the pouch;
• an elastic cord retained by the anchor and extending around the sidewalls;
• and
• a tension adjuster mounted to the elastic cord and configured to maintain a stretched portion of the elastic cord under a selected tension by selectively restricting the elastic cord from moving relative to the tension adjuster;
• a coupler mounted to the pouch and configured to selectively mount the magazine retention system to an object, the coupler including:
• a panel defining spaced slits and having a first end;
• and
• a strap coupled to the panel at the first end and complementarily configured with the spaced slits to selectively insert into a selected slit to define a coupler loop with a loop size defined by the space between the first end and the selected slit;
• wherein:
• the tension adjuster and the elastic cord cooperate to selectively compress the sidewalls to secure the ammunition magazine in the pouch interior;
• the strap includes a head distal the first end;
• the head is complementarily configured with the spaced slits to selectively insert into the selected slit;
• the head has a head width wider than a corresponding slit width of the selected slit when the head is oriented flat to restrict the head from pulling through the slit unless the head is selectively bent to reduce the head width to be narrower than the slit width;
• the elastic cord extends through one of the spaced slits away from the first end between the panel and the sidewalls until an extension portion of the elastic cord extends beyond the panel and the pouch;
• and
• the tension adjuster is mounted to the extension portion of the elastic cord extending beyond the panel and the pouch.
