Thanks, backhoe! Hubby and I are making another ammo run this afternoon and I thought I’d try to find one! Thanks again!
Best wishes to you both- couple of things occurred to me on further thinking—
Some tacticians advise not being too concerned about the magazine capacity, they’ll tell you to practice reloading at every opportunity- keeping it “topped up.”
The old Army issue shotgun shell carrier is pretty good— it’s flattish pouch that holds 12 shells in loops, and clips over a belt. It’s rather small.
Another I like is the old M-60 machinegun belt carrier pouch- it has a strap to throw over your shoulder, and you can stuff a box of shotgun shells inside, or dump them loose and fish them out. Not elegant, but keeps reloads handy.
