I will just leave this here then.... Fully dehumidified safe, every single other gun in there was 100% fine even the 1955 Colt Woodsman Target model in carbon steel. Kimber is the 1911 for people who know nothing about 1911's. They are proof positive pretty guns and lots of advertising works extremely well. Do your research and get a better 1911 folks.
Thats funny, I have a stainless custom, been in my safe for years with no marks. Maybe you need a better safe...?
