Hey guys,

 

Need some advice or help here... Was looking over my new S&W 1911 and notice something in the barrel that looks like it could be rust, but I'm not sure. I used both MPro7 and Hoppe's #9 solvent (not at the same time... on separate cleanings) and ran a brass brush through the barrel a few times, but this stuff is still there. I have included a pic to show you what I'm talking about... It looks like an orange/brown color running along the ridges of the rifling. It's only along the rifling and nowhere else inside the barrel. What do you guys think? Is it anything I need to worry about? Could it just be copper from when it was test fired at the factory?

Looks like copper residue from jacketed bullets to me, and I hope it is.

Nothing to worry about. Minor

it's minimal copper fouling from jacketed ammo.

Thanks guys... I think I feel a little better now. The pistol is brand new and I haven't even fired it yet, so I got a little worried.

You need copper solvent after powder solvent to remove those streaks with any firearm shooting jacketed ammo. It is normal. You will not get rust in a stainless barrel (and your barrel is indeed stainless)

 

I reccomend KG-12 and sweets 7.62 for copper removal.

I highly suggest using sweets 7.62 every other or maybe every 3 cleaning sessions. That stuff is sooooo nasty I not only want to clean with it but I can only imagine that repeated use could cause excessive wear on a gun but I have no info to back that up. I use sweets every so often.

Thanks G. I have a bottle of Mpro7 copper remover coming to me in the next few days, it was on backorder when I ordered it a few days ago... so I'll give that a shot when it comes in. Funny thing is that after 600+ rounds of ammo in my Beretta, I don't have this kind of fouling... but here on the brand new 1911, it's there and I haven't even fired it yet.

Just as a point, there's NO point in worrying about the copper fouling yet in terms of cleaning it. There's no point in beating on your barrel to make it shiny if it is shooting well.

KG-12 works just as well as sweets but with no stink. sweets wont trash your barrel if used right, it just smells like it will because of the ammonia. Tony, im sure your beretta has the same streaks. Look at it carefully from an angle.

Another trick for copper removal is heat up the barrel with a hair dryer or lightly with a heat gun LIGHTLY and the Hoppe's #9 will work fine.

Like everyone else said I think its the copper, cause I get that in my px4 barrel.

Just copper fouling as others said. Normal, nothing to worry about.

+1 on KG-12. Kicks butt in the copper removal department, and doesn't stink at all. I use it every 3 or 4 cleanings.

 

Don't chase the "i don't want to see any brown" demon. Seems there will always be a little there, no harm no foul.
