" But storing magazines full of bullets was a bad idea. Leave them long enough, the spring in the magazine learns its compressed shape and won’t function right. More jams are caused by tired magazine springs than any other single reason. Better to keep the gun with a single shell locked in the chamber and all the other bullets loose. You can fire once right-handed while you thumb loose shells into an empty magazine with your left. Slower than the ideal, but a lot better than pulling the trigger and hearing nothing at all except a dull click. He closed the kitchen "
