    Not uncommon. That's why current models have beveled and lowered ejection ports. As long as it doesn't affect reliability it's usually been considered acceptable though it does dent the cases. If you're ok with that...no harm.

    As above this is not at all uncommon with the design.

    Often this can be limited by re-tuning the extractor and ejector, but this is the reason that Colt began lowering the ejection port and putting the bevel on the rear of some models ejection ports.
    This was first done by 1950's target shooters who hated getting their brass beat up because they reloaded. They began putting the bevel on the slide so ejected cases could roll out easier and not dent the mouth.

    Dented case mouths is not an issue at all.
    If you reload, the loading dies will simply push the dent out and it's not a problem.

    If it's a defense gun, as long as the gun is reliable what condition a fired case is in is of no importance whatever.
    All that matters in a defense gun is, is the gun reliable?

    I had a new series 70 that did that along with randomly ejecting brass into my forehead. After tweaking the extractor,both problems were solved.

    Dented cases are common with all 1911 models that haven't had the ejection ports modified, not just Colt's.
    Like Snidley and dfariswheel said...its not a big deal.

    If the brass hitting the slide as its ejected causes reliability problems then the problem is somewhere else...not the design of the ejection port. That in the past gunsmiths promoted lowering and flaring the ejection "enhanced" the pistols reliability is more hype on their part than anything else. It's a selling point...not a necessary thing...but most everyone does it now so it's considered necessary to compete in the market. The lowered ejection port is a boon to reloaders though. That's probably why it was always done on the Gold Cup.
