"You're not taking enough care of your guns if they're rusting.."
Ok, then please tell me what I'm doing wrong since you know so much about it.
I clean the barrel with bore cleaner, then wipe dry with a cotton rag, and use Hopps 9 to wipe down the other parts, then wipe the whole gun down with Eezox before storing in my safe which has four dry bags, plus one of those moisture catchers I bought from Walmart.
I do this once a week, but on my old blued Shotguns it still doesn't help.
Again, I'm not knocking people who like bluing, but don't say I don't know how to take care of my weapons. I learned good cleaning habits when I was about six when I first started shooting, and I am still practicing them.
Another issue with bluing, for a hand gun, is pulling it in, and out of the holster as this will also start to remove the finish.
If I had a rare weapon that I kept only as a safe queen then it wouldn't be so much of an issue, but for weapons that get used regularly I prefer parkerizing on my rifles, and stainless {or parkerizing} on my pistols.
