    I'm a bit confused on how the LCP ejects spent casings. From what I read on the internet, the extractor pulls a casing back until it hits the ejector. The ejector then hits the casing on the left so it flies out to the right, and the whole process relies on force generated from the explosion of the cartridge which causes the slide & extractor to move back.

    My question is does the magazine play any part in the ejection process? Does it generate an upward force to cause the casing to fly to the right as well as upward? Bottom line is I'm trying to find out if a weak magazine spring will cause FTE(eject) instead FTF(feed) issues. Also I'm asking about all modern semi-autos not just the LCPs.

    Welcome to the forum CrazyJoe! I don't believe the magazine comes into play in the ejection process. my answer is based on the logic that the last round fired ejects fine with an empty mag. I also know my SR9c shoots and ejects a round without a mag. great. I removed the mag. safety on day one. Den

    Hey Joe, throw your weapon concern or issue out there and someone may have a fix. Den

    The simple answer is no.

    With almost any auto pistol - if you were to manually charge the chamber with a live cartridge without even having a magazine in the pistol and then fire the round (a process that some pistols cannot do because of an interlock device requiring the magazine to be in the pistol), the expended cartridge case will still be extracted and ejected normally.

    Hickok has a video saying ejection is affected by the mag. Cases were not clearing the slide with the mag removed.

    What pistol is that video about? Something specific or is it a generalization?

    In the rather distant past, I've fired several of my autoloading pistols with only a round in the chamber and no magazine and cannot recall any failure to eject the expended cartridge case.

    I tried to find it but a channel search didn't bring it up. He was shooting a pistol and it happened and he said it was talked about in another video. If I find it I will post it.

    Found it. About 6 minutes in , a stove pipe with the mag out:

    That was quite interesting to say the least. I don't think I've ever run a test quite like the routine in the video but I know I've occasionally shot a round here and there with no magazine in the pistol and never run into the stovepipe problem.

    The solution is simple, of course. Use a pistol with a magazine in the well.
