If it's what I think it is, the brass being caught in the ejection port as the slide begins to slam home, it's a relatively common problem. My Springfield 1911-A1 will occasionally do that.

One of the solutions is to lower and flare the ejection port to allow the case more clearance as it is ejected.

I guess the idea is that, as the case is ejected, it bounces around and slows down just long enough that the slide catches it and smashes the case mouth into the front of the ejection port.

By lowering the port, the case can clear the port without being slowed down too much.

I've thought about having the port on my 1911 lowered, but quite frankly I don't lose that many cases (maybe 1 in 50) to mouth tears, and .45 ACP brass is very cheap.

The only reason I'd really consider having it done is if I was having recurring smokestack jams.
