Years ago my grandparents property was sold and the old house was going to be razed, my dad and I went to ck the old place out nobody had lived in it for years, anyways we found several old boxes, and on we found no guns but we did find a shoebox full of old 1911 mags still loaded, the he brought back from Korea, (marines) we thought no way would these things still fire, at the time those mags had stayed parked in that shoebox for 50+ years, not only did they fire and the mags still work that old ammo still seemed to have a lot of snot left in it
