I just got a new Colt 1911 Combat Commander XSE.  

I field stripped everything lubed it up good, took it to the range.  At this point there were no scratches at all on the pistol that I could tell.

Fired around 300 rounds through it.

Disassembled and noticed a long scratch almost from where the slide stop is inserted to the assembly notch it rests in ( the scratch seemed to correspond with the cutout on the inside of the slide stop).

Is this a normal wear point on the gun to where it would scratch after only 300 rounds?  Or should i get a new slide stop?

im not talking about the "idiot scratch" that happens during re-assembly.  This scratch is completely covered by the slide stop when the gun is assembled.  

apologies as im sure this is not a very interesting post, i just dont like to scratch up my guns if I can help it.

Thank you very much for any insight you may have!

You could try and sand it down (slide-stop) to reduce the ammount of friction in that area but as long as its functioning it should be fine. They will get scratched up and worn if you shoot them. It just happens.

Remove slide-stop. Find rough/high part that is scratching. Polish/sand smooth.

I agree sand it down to fix it. I had a springfield stanless do that. Called springfield and they said it was normal. But my colt and STI don't do it. So I gotta go with it ain't normal.

Hey guys,

thanks for the replies.  Looks like ill be getting some sandpaper in the morning.

Any ideas on getting the scratch out?  will super fine steel wool and some polish help or will that do more harm than good?

Unless its gouging the steel I wouldnt worry about it. Shooting a 1911 cruds going to get in there and wear of the finish under where the slide stop moves. Nature of the beast and all.

this is absolutely correct, you will not find a 1911 that will not eventually have finish wear under the slide stop-no worries.  i wouldn't go sanding anything at all, that might cause problems.

He makes it sound as though there is a burr on it. Sanding it down carefully so there are no rough spots is nothing short of what a 'smith would do on a high-end 1911 imho, so why not? Sure the finish will wear, but there is no need in it not wearing evenly

I had a burr on a C&S slide stop that was causing my slide to not lock back every time. It wore through the finish and actually created a deep scratch in my frame. Smoothing the slide stop surface out with 400 then 600 grit sandpaper made all the difference in the world. However, the scratch is still there but it happens.
