Why does it occasionally happen? I have a few semi auto pistols of various makes that occasionally will eject a round or two to the left rather than the right, and I am curious as to why. It has happened with my G17, a couple of my Sigs, etc, and all have good extractors, and ejectors. Ammo and mags have been swapped around and no one ammo or mag is attributing. It is not a big deal, as stated prior the reliability has been 100%, but I am just curious as to why it happens? If it helps, it does not seem to happen ever with defense ammo, and it is on the last round of the mag usually. Is it that there is no round left in the mag to keep the extracted round from dipping down further, and thus the ejector hits the rear of the case lower at times, thus causing a weaker and sometimes left sided kick out?
