[Mark IV Series 80]

I have heard of fully loaded 1911 magazines put up right after WWII, and when they were discovered many years later, they worked perfectly.

However, I like to test my guns and ammo and magazines to make sure everything works. I fire all of the ammo in all of the loaded carry magazines at least once every two months. Then I replace the magazines with different, clean magazines and new carry ammo. This way, I rotate through all the Wilson magazines, and I know that the magazines and ammo will perform without fail.

Magazine springs are inexpensive and easy to replace.
