1911's do this, because the ejection
port is too small, and not "flared" at its rear, the way the Gold Cup's port is treated. It can also be helped or hindered by different ammo, stronger or weaker recoil springs or extractor tension, and by a longer or shorter ejector-nose. Use a round of hardball, and maybe needle nosed pliers first, to swage open the case, before resizing it, and it will be ok.
