Based on recommendations from you guys, I sent my slide and both mags to Jack Fuselier for nickel plating. I know you guys like pictures, so here are some before and after: BEFORE - slide rust! AFTER - nickel! Here's my blue P-11 mag next to the nickel 380 mag for comparison And the finished product The work looks great; you can see the pitting where the rust was, but Jack mentions on his website that nickel will show that sort of thing. Overall I am very pleased and glad I did it. I did have one small issue that I think deserves mention - after I reassembled the gun, I found that it would not chamber properly from a full mag. The slide would get hung on the way forward at the point where it contacts the back of the round to strip it from the mag. A slight bump to the back of the slide and it would chamber. If I only loaded 3 or 4 rounds, it was OK, and it happened with both mags. I finally noticed that there were scratches on the brass casings (I was cycling the same 6 rounds over and over), and figured out that the mag lips were cutting into the brass. I spent a few minutes beveling the front of the mag lips with a file, and now it feeds like new! If anyone has the same symptoms after plating, this might be the cause. Thanks for the recommendations to nickel plate (no more rust worries). Now I just have to make it to the range to see how she shoots!
