Glock safety issue?
Never heard of this one. And I can’t wrap my head around how that could happen. Color me skeptical.
Remember, I do this to entertain me, not you.

That’s one warped pistol to do that.
OTOH, any platform with an inertia firing pin can discharge upon loading, in any caliber. My AD was with a 12 gauge 870 while doing one handed reloading drills at gun school. It was “exciting”.
Have been in class where an AR (a Les Baer) did this. Saw it happen in a gun store with a 1911.
Guns do discharge with fingers off triggers, that’s why the Four Rules light is always on.

Go back to Anarchangel’s post and re-read the comments. Eyewitness reports are coming in now, so it DOES happen, but apparently only to modified guns, and NOT just Glocks, even more to S&W autoloaders.
Note to USPSA: since you are SO picky about rules, why aren’t you picky about unsafe gun mods? Seems to me that lengthening the ejector prong could make it easier to bend, and it’s only a problem if it bends. All competitors with the idiocy to modify a gun in that way to get it to operate marginally faster should be sent home and never allowed to compete.
I have a certain disrespect for USPSA anyway, since it seem that the outfit is just as much about making speedy guns as it is making speedy competitors, and that’s wrong, IMHO. Yes, they have a “box-stock” class of some kind, but all the top competitors use guns that are so highly modified that you and I would have to take a second mortgage on the house just to own one.
Meh. Leaves me cold.

True dat on the firing pin.
With many gun designs it’s possible under the right circumstances for the firing pin to ignite the primer on chambering. Imagine a dirty chamber that pushes the cartridge back a bit, or a case that’s stretched.
Communist block guns seem to be the worst for it. The original Russian SKS had a spring around the firing pin to keep it from happening, but the satellite copies didn’t. There’s a guy who sells the spring and firing pin to prevent it.
I read a blog post a few years by back (I want to say by Larry Correia) about his Commie pistol slamfiring and going full auto because of the firing pin.

Rivrdog,
“…and NOT just Glocks, even more to S&W autoloaders.”
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.)

In other news; chainsaws can be dangerous too. We handed one to our son when he was 13 and told him to clear out some plum trees, whereupon he did so, without adult supervision. We did not need a permit, nor did the seller of the chainsaw need a special license, yet our son could have easily taken his face off. This occurred within city limits too, and no one shit their pants, called the cops, or convened a safety committee.

In 1997 Chicago PD had trouble with Sig pistols discharging when chambering. A Sig fan sent this to me several years ago.
This specifies a partially loaded magazine, but other than allowing a bit more bounce, I don’t know that it would matter.
“SIG ARMS MODELS P225, 226, AND 228
These weapons have been found by the Chicago Police Department as
having a design flaw that can cause detonation of ammunition in
the magazine when chambering the first round of a partially
loaded magazine.
It appears that if the partially loaded magazine is slapped into
place, the top round may expose the primer of the first round to
the breech block as the slide moves into the battery position.
Sig Sauer has recognized this problem, and has modified all of
the weapons owned by Chicago Police Officers. …”

Switch to a titanium firing pin. They move faster and hit harder when pushed by the hammer (energy increases to the square of the increase in velocity), but don’t float with any great amount of force.
Regular titanium (99%) tends to spall and gas burn. Specify 6AL4V alloy that’s been age hardened. 150K yield point, as compared to steel at 112K and soft titanium at 50K. They build the hot sections of jet engines out of the stuff.
The first 10 1911 owners who write me at Continental Machine and Tool Company, 533 John Downey Drive,New Britain CT 06051, get a free Ti6AL4V firing pin.
Sorry, the high pressure (.068 diameter) pin, usually used for 10mm’s, .40S&W’s, and .38 Supers, is all we have in stock. The big fat .093 diameter doesn’t punch as deeply into the primer or light it off as well, so we build our guns with the faster, smaller pin tip. Have somebody with a micrometer or dial calipers check your pin to see what size it is.
