I am new to the wonderful world of pistols, and recently purchased a p320 and p938. I took them both to the range for the first time today, and ran through probably less than 50 rounds in the p938. I loved both firearms, but I noticed a gold (or bronze?) streak on the slide of the p938. I'll include a pic at the bottom of the post. I know it is probably nothing to worry about, but I am just curious what could have caused it so I can make sure not to get this beauty all marked up before even breaking it in. All I have right now is some gun oil, and I couldn't clean the streak away with it. Maybe some better cleaning solution would do the trick. The only thing I could think of is it may have something to do with a bullet casing or something. Any idea what it could be from and a recommendation for some good cleaning solution?

Have no idea what could have caused the gold streak??????????????

it is a mark from the brass.

Thanks for the welcome and for the quick responses. I figured it had to be from the brass shell, just wasn't sure how it coulda happened. Maybe I set it down on a bullet or something. Can't remember which gun it was but one shot a shell straight up..maybe it came down and hit the slide. Not sure if that would have done it, though. So that sounds like it's nothing to worry about, like I hoped, so I don't have to worry about it being more susceptible to rust there? Mississippi sure is humid; guess I'll keep her with a nice coat of oil on at all times. Anyone have a good cleaning solution to recommend for future reference?

First off, welcome to Sig Talk, from the southwest corner of Indiana. You shouldn't need anything special, I would suggest CLP as your primary solution. You may get a small bottle of bore cleaner, for the occasions of removing brass marks as you have shown. The CLP will clean, lubricate, and protect your firearms. I would suggest grease to use on the slide rails where the slide reciprocates back and forth, a little last longer than oil which can get slung off, being so "thin" in viscosity.

I agree with brass too.

The P938, being so short, will spin shells a lot faster than full size pistols. They tend to rebound in weird directions.

Most likely a brass streak (unusual spot for that) but could also be from contact with a gold ring.

From the color, I think it's something on the finish and not the finish scratched off(but the pic may deceive) I would use a little solvent and a firm (usually blue bristles not the white) nylon gun brush, and see if it will scrub off. Either way the slide is stainless steel so rust should be pretty minimal anywhere on the slide.

I agree with all who have said brass streaks. As for cleaner, man there are a lot of choices out there and would imagine everyone here has their own favorite. For me it’s Hoppe’s #9 with a bore snake and Birchwood Casey SNO Universal Gun Grease. I am not saying this is what you should use just what I use. Oh by the way Hoppe’s also makes a great aftershave LOL just kidding

I concur that the gold/brass streak is either from ejected brass casings, or a ring on your left hand making contact with the slide when charging the weapon. It will come off with a little Hoppes No. 9 solvent.

Yep, mark from the brass and welcome from Western North Carolina.

It's a badge of honor.
Welcome to the forum.

I'm going with the gold ring theory. It happens, you'll either have pretty guns that you never use or this.
