This replacement part is a factory original
from Ruger. Factory replacement parts are manufactured to the exact
same specifications and tolerances and use the same manufacturing
materials as the original parts which guarantees excellent fit and
reliable operation.
This magazine features a rugged polymer body and magazine follower. The
metal feed lips will stand up to thousands of rounds without any signs
of wear or jams. The Ruger rotary magazine is superior to conventional
feeding systems because each cartridge lies in its own channel in the
magazine. This arrangement prevents jamming by eliminating the overlap
between cartridge rims found with stack-type magazines. Keeping a few
extra factory magazines around is never a bad idea; extra magazines
save loading time at the range and also serve as a backup for those days
when you simply cannot remember where you put your primary magazine.
