Plastic works fine for toys and casual use, but has proven
molecularly unstable in extreme environments, vulnerable to changes in
humidity, and unable to retain shape during extended use. DURAMAG is the
one magazine design that you can rely on during a sunny day at the
range, frozen night on the tundra, in the sands of the desert, or
pulling from long-term storage. Relentless reliability because a firearm
is only as good as its magazine.
