Dented cases on 10 mm cases normal for 1911?

[Rmiked]

I noticed small dents on side of ejected 10mm cases on my Dan Wesson Specialist. The pistol functions fine. There are also some collision marks on the forward face of the slide adjacent to the ejection port. Is this normal for a 1911? Again the pistol ejects very well. Pictures below.

I have had 1911 45's dent brass especially the case mouths. In my instances tweaking the ejector resolved the issue. My gunsmith tweaked. I remember this to have been fairly common. He slightly modified the face of the end of the ejector from flat to a slight angle. You don't want to hear this, but unless you are reloading these cases, it is a non issue. And if you are reloading the cases, it most likely is a non issue. If put before a gunsmith, you risk having a ham handed person screw up your nice pistol. I urge you to call the maker. These are outstanding 1911's. I would trade blue's pension for one and blame it on his nemesis.

Not denting case mouths. I have not bought dues for 10mm yet with primer shortage. The marks on the slide rim, perpindicular to barrel, must be spent cases colliding. I can’t see how the rim of case or mouth of case could hit that surface. And the side of case couldn’t make a mark? Must be the case spinning so fast the rim is hitting on way out? I emailed Dan Wesson with same pics. See what they say. I am hesitant to do anything about it. Pistol runs fine

That minor ding is almost certainly impact with this corner of the ejection port. Not unusual at all.

So the dings on the stainless steel are caused by the case mouth hitting the flat face (perpendicular to barrel) as the case is spinning during ejection? My cases go 10-15 feet. IMO it has very good ejection.

It is common to find "brass kisses" on the portion of the 1911 slide just to the rear of the ejection port. It is more common with the smaller diameter cartridges as the extractor and ejector are bit more inboard. The ejector can be tuned to throw the cases a bit less to the rear but I would not mess with a functioning pistol. If the finish of the slide shows brass marks, get some copper solvent, apply it to the area with the brass marks, wait a few minutes, and then wipe the brass marks away with a clean rag. This is safe for most finishes with the exception of electroplated nickel as that finish uses a copper primer coat which would be attacked by the copper solvent.

I wouldn’t really sweat it, OP.



My 10mm experience is limited to a series of lightly touched Colts, but I always get brass marks behind the ejection port.

Perfectly normal with 1911s, not just 10mm.

I appreciate knowing that. One thing I’m curious about is the circular scratches on the stainless steel slide face in ejection port; the face that is perpendicular to the barrel. I don’t really care about the appearance, I just can’t imagine a brass case hitting a stainless steel part, and scratching it? It is not brass marks. You can feel it with a toothpick. It is actual scratches. If you look at the picture you can see it. So you have seen that on other 1911s? It must be the case rim as it spins out of pistol. My spent case rims are NOT bent or fish-mouthed.

Those look like chatter marks from the machining process. Funtionally, nothing to worry about.
