View Full Version : Help; 220 is rusting.

November 21, 2015, 13:51
I spent a week in the E Ky mountains camping. Sig 220 spent the whole time in a range bag in the back seat of my truck. I never took it out. When I got home and pulled it out the slide was covered in rust. I've never had a gun rust like that other that a AK that got rained on. It does this every time I take it somewhere for more than a day. I've tried CLP, Kroil, Rem oil, nothing helps. Is there anything that will stop this?

If this happens everytime you take it somewhere for more then a day in your range bag...
I would think your range bag is retaining humidity or moisture. You could probably deal with either one if you had ventilation. JMHO and worth everything you paid for it!!

A silicone bag may block it, but once it shows its ugly face it would be hard to block.
Good Luck!

Time for a new range bag and add silicon dioxide packets to the new one. You might also try putting your oiled pistol in a plastic bag first.

This is the only (blued) gun I have that rusts. I'm more concerned that there was a problem during Sigs bluing process. What is out there that inhibits rusting metal?

Ceracoat or Metalcol.

I have a P220 West German that had the folded slide rust in my pickup under the seat. I didn't notice it until after a month or two of me wearing boots in the winter and snow and ice on them melted leaving a pool of water at the same elevation as my gun.
I reblued and got a nice finish but I don't put that 220 under the seat anymore. That's one reason I am looking for a better weapon for carry/car duty. I think there are guns with more corrosion resistant finishes than 1990's sig's.
I'm curious about the corrosion resistance of my new 320.

This is normal in the earlier SIGs. They do that, unfortunately.

I had a P226 when I worked in the tropics and made sure to keep it wiped down regularly.

Mine was blued but the K-Kote SIG offered wasn't much better; a buddy had one like that. The finish simply didn't seem to last very long with daily carry.

I never wondered why SIG went to stainless slides when they released the P229s.

Since I shoot the P226 quite well, when I returned to the States I knew to look for one with plenty of finish wear but that had seen little actual use.

Blast & park.

Or like the BP guys, pull the grips, and throw it in a bucket of WD-40 for the trip home.
