mag rust

[zorkieo]

my dw 1911 blued mags rusted afer 2 weeks of shooting. why so fast? will stainless be the same? i have never seen anyting rust so fast from a bunch of non-corrosive ammo

Stainless steel will not rust. It weighs more though.

The rust is likely due to moisture rather than what ammo you use.

Or from handling the mags and not wiping them down. Sweat is very corrosive.........even to stainless steels.

Do you live anywhere near the ocean?

I live exactly 1 mile from the beach, I find I have to run an oily patch through the barrels of my handguns and rifles, if I haven't fired them for a month or so, to keep the rust away.

Correction... stainless steel kept dry or oiled will very rarely rust. Even stainless isn't completely impervious. If you keep stainless submerged in water long enough, it'll manage to find its way through the chromium layer that forms on the surface.

I found the following article on stainless steel to be fascinating, from a metallurgical perspective, and encourage anyone who wishes to better understand the protection of their firearms, to read it:

In short, I would recommend giving your mags a light coat of CLP for storage. It's how I store my extra AK mags nowadays.

Yup, the quote is "stainless isn't".
