New member has a question about shells' not always ejecting as they should. I have a Herstal FN Hi Power I'm told is of 1952 manufacture. It works fine except that most times (not all) the last shell in the mag doesn't eject after firing. The last round loads, fires, and extracts normally and the slide locks back, but the empty casing remains loose at the ejector port and isn't kicked out. Preceding rounds all load, fire, extract, and eject fine. Does anybody know what is going on here and how I might cure it? Very grateful for any guidance.
