Hello and welcome. I bought my Kimber Super Carry Custom HD. There are a few reasons I bought the particular model other than its looks and ambi controls. I've heard that some of the newly produced kimber barrels rust fast. Well That is why I did the kind of research I did and found an all stainless gun. If you look on the Kimber site you'll learn that the listings describe which firearms are made of what. Most of the custom II barrels are "steel". That's carbon steel to be exact. Of course you must consider the environment you are in, but it is true that after shooting and not cleaning and lubing properly the barrel, it can rust due to the materials used to make the barrel and the elements provided by nature, "salt in the air" such as near the coast. Try Eezox. The fact is, when demand was increased by panic buying, the manufactures had to come up with ways to keep up. Well, carbon steel is easier to mill than stainless steel, is the story I got. My suggestion is, don't be discouraged. Buy a SS barrel if you can. Kimbers are worth the extra cash if you look at the other elements going into the firearm as its made.
