Inserting and Removing Cartridges from the Magazine
Note: The magazine cartridge lock
4 in Figure 14 on page 52 must be in the
unlocked position before you insert or remove cartridges from the
magazine. The door
3 of the magazine 1 will be damaged if
cartridges are moved with the magazine lock in the locked position.
The cartridges are removed with the least effort by pressing the label end of
the cartridge to the right while pulling out. (To the side of the magazine
opposite the magazine lock.)
Note: Always engage the magazine lock
4 (Figure 14 on page 52) before you
transport a loaded magazine to avoid dropping the cartridges or
shifting their position in the magazine.
