Marks inside chamber 1911

[BadFishQuint]

After first inspection everything looked good except for the inside of the chamber that had machining marks. I thought this was normal being a national match barrel and never owning a 1911 style pistol before. After fireing I found that the spent brass have the same machining marks imprinted on them as the chamber. The spent brass have lots of soot more on one side than another. I also thought this was normal and was hoping all problems would go away after some more time different factory ammo and a break in period. It did not and is getting worse. Hand cycling the slide or hitting the slide release to chamber a round with a loaded mag will dent the nose of ball ammo and also scratch and gouge the case brass. Something is just not right with this gun and or the barrels chamber. It seams like something was missed in the manufacturing process or inspection of this firearm. Even the out side of the barrel looks rough.

I would send pics to the manufacture, ASAP!

Yeah, that doesn't look right to me. Almost looks like a fluted chamber, but there would be no reason for that on a 45acp. The ramp at the bottom looks too steep and and generally not right. Looks like the reamer may have spun in the toolhead during finishing and just got pressed into the chamber. Don't think that one should have left the factory. I'd definitely bring it to the attention of the manufacturer. Appears to be a Colt barrel, is it new production, or a used example? Not familiar with Colt's warranty process

Ain't right. Especially if it claims to be a National Match barrel.

It's a new colt 70 series competition with national match barrel. I had a feeling something was not right.

Nothing right about that chamber at all.

Even the out side of the barrel looks rough.

Got pics of the outside?

Classic sign of reamer chatter. Must have been chambered close to quitting time and was rushed. Colt should make it good. The chatter marks could be polished out but the chamber would be slightly oversized when done. Should not have to live with that on a new gun.
