waRning – unloading
removing cartridges from the magazine
does not prevent the pistol from being fired!
When there is a cartridge in the chamber and
the safety lever is in the “f” (fire) position,
the cartridge will discharge if the trigger is
pulled. it is absolutely essential for the user
to know how to completely unload the pistol.
“completely” means emptying the magazine
and removing a chambered cartridge.
the safety leVeR should always be
in the “s” (safe) Position when the
Pistol is being unloaded.
the Pistol will fiRe eVen
if the magaZine is emPty oR RemoVed
to extract and eject a chambered cartridge
When the pistol is fired, the same gas pressure which drives the bullet forward also acts
through the cartridge case to push the bolt to the rear. That action causes extraction and
ejection of the fired case. But, when the bolt is operated by hand, there can be a failure to
extract the cartridge from the chamber, or a failure to eject the cartridge clear of the pistol.
These failures usually are the result of the bolt not being pulled rearward vigorously, coupled
with an accumulation of firing residue in the chamber.
from the foregoing it is clear that the gun user must:
1. always visually check the chamber after opening the bolt to eject a chambered cartridge.
if the bolt is not vigorously retracted when being operated by hand, the extracted cartridge
can be “ejected” into the magazine area instead of outside the pistol. (remember that the
magazine should be removed prior to unloading the chamber.)
2. Thoroughly clean the chamber and the extractor as often as necessary to prevent
accumulation of grease and dirt.
3. if an empty magazine is in the pistol when the bolt is being hand retracted to extract a
cartridge, the cartridge may drop on top of the magazine. Then, when the bolt goes forward,
the cartridge will be chambered again! always remove the magazine before clearing the
chamber, and visually ensure that no cartridges remain in the pistol.
