Caution.....the "indentation" that Glockolive mentions, and says is the problem, is not the problem....it is there on purpose....don't mess with it. It helps "hold" the cartridge during the firing process, when the other side if the rim is held by the extractor claw. It amazes me on gun forums like this that people present problems and don't take measurements. So lets do this. True enough, the ejection port is meant to be large enough to eject empty shells, but ( also true enough), it still SHOULD be able to eject a loaded round. This becomes ever-more-difficult as the guns get smaller like these pocket pistols.
So here goes-->
- According to SAAMI drawings.... a .380 loaded cartridge has an overall length of 0.980" to 0.984", depending upon bullet type and weight.
- I measured the TOP of the ejection port opening and it's 0.989 " ( ! ).... very little margin.
- I measured the mid-point "side" of the ejection port opening and it's 0.938" on the curved surface, and 0.944" at the top of the extractor.
- Note....bullets can range from 80 to 100+ grains.
This guy in this vid, noticed the same thing....and stuff like this was also found by 1911 guys who fixed it by "lowering the ejection port". See this vid, it helps what can be done and it WILL help the situation. Alternatively.....YES.....breaking-in the gun with some number of break-in rounds will help too...and a "snappy" movement of the slide by hand also will often do the trick, but not a soft/gentle pull. See here, rounding the front/bottom and lower edge of the ejection port fixes brass scrape issues, and also marginally "opens-up" the ejection port area--->
