In response to the posts here and here about some new way Glocks are allegedly going 'splodey, by detonating loaded rounds in the feedway when someone's trying to "unload and show clear" at the end of an IPSC or IDPA stage, either due to the extractor or the ejector contacting the primer:
Any Browning-pattern pistol can do this. You don’t even need an extended ejector. 1911s were doing it back when Gaston was still making curtain rods and folding shovels.
If the live round doesn’t fully eject because some goober has his hand over the ejection port to prevent his valuable 23¢ investment in a round of FMJ lest it get dirty by hitting the ground, and his hand slips or he runs the slide back and forth and back and forth, it is possible for the extractor or ejector or even a corner of the ejection port on some designs to bust the cap and fill his hand with shrapnel from the casing.
Don’t try and catch the round you’re ejecting. Don’t put your hand over the ejection port. Keep your hand away from it and let the round fall on the ground. It will be there when you get ready to pick it up, I promise. (And if it’s not, you can just buy another one.)
