BudsGunShop.com - Subject to rust easily?

Have had other blued pistols and they seem to have an issue with rust in humid environments.
Is there a difference in the steel and bluing on these barrels that give them more resistance over other barrels to rust in humid environments?
Have some blued pistols that seem to rust easily and others that stand up to the humid conditions even though both are treated the same.
