magazines were considered the future in magazine development.
Light weight and cheap to produce, SWD thought they
had a break through with magazines produced using the
material Zytel. Unfortunately this was not to be the
case. The M-11 magazine design was not very friendly
to magazines made out of Zytel and this decision led
to a host of reliability problems that stemmed from
Over time the magazine
feed lips would be worn away & the pressure from
loading a magazine near capacity would cause the magazine
lips to spread out. This led to jamming & miss-feeds
because the feed angle of the round was altered. The
glue used to bind the two halves of the magazine would
also come “unglued” and the magazine would
split rendering it useless.
Unfortunately for the
SWD guns a lot of the stories about the gun being a
“unreliable pos” were a result of the magazine
and not the gun.
Before metal replacement
magazines were in country from South Africa & Argentina
a lot of people had there SWD guns converted to Sten
or UZI magazines during the AWB years (1994-2004) because
decent replacement magazines were hard or nonexistent
to come by.
Today a few of the past
issues with the Zytels have been solved. You can now
purchase steel feed lips for them and now that the magazine
ban is over with new replacements can be purchased.
find Zytel magazines ranging in a number of capacities
from 10 to 32 rounds usually for both the 9mm Luger
and .380 ACP M-11s.
