inspect the magazine frequently. The magazine follower must move freely and have adequate spring tension so that each
cartridge is quickly raised to the feeding position. The magazine lips should be clean and free of cracks, dents, or nicks, so that
cartridges are held in their proper feeding position.
When cleaning is necessary, use a solvent that will not rust the metal components or adversely affect the magazine follower.
after the magazine has been soaked in solvent to loosen foreign matter, be certain to shake it vigorously (with the loading
opening away from you) to remove solvent or residue from within the magazine.
Penetrating oils and solvent inside a
magazine can “kill” or weaken cartridge primers, which can result in failures to fire or other possibly dangerous
malfunctions, such as leaving a bullet in the bore!
after cleaning, always check to be certain that the magazine follower movement and spring tension are correct, and that
no solvent or debris remain. improper reassembly of the magazine spring can cause a potentially dangerous
malfunction. if cleaning does not restore proper tension, or if you experience a problem with the magazine, do
not use it. get a new one.
