PPQ failure to extract

I was at the range last evening shooting my 9mm PPQ when something unusual happenned. After I finished shooting, I noticed the gun didn't eject the last round. I thought maybe the chamber was empty and the slide didn't lock back for some reason on the last round. I tried to pull the slide back manually and it wouldn't budge so I knew there was a round in there. I pointed the gun down range and pulled the trigger to try to get the last shot to fire...nothing. I dropped the magazine and attempted to pull the slide back, wouldn't budge. I finally got the slide to budge about 1/8th inch and my friend slide the blade of his knife in the opening and pride something loose and I was then able to retract the slide and eject the unfired round.

Any idea what caused this, it happened 2 different times. I measured the round with a caliper and there was nothing unusual about the size.

What were you using for ammo, could have been overloaded. If it's reloads it could have been not sized properly or overloaded a bit. Factory ammo does have issues now and then. I say it's an ammo issue and not your pistol. PPQ's have polygonal rifling, so don't shoot non jacketed ammo from them. They are like Glocks and HK's same type rifleing.

Do you still have the stuck round?

Was the primer struck by the striker?

If it was, I'd assume that you got a bad round that possibly had no gun powder in it. If the primer pushes the bullet into the rifling, but not all the way out of the casing, the pistol will lock up.

Are there markings on the bullet?

Without more information, I think it is an ammunition issue too, but the PPQ has the standard "lands and grooves" rifling. It is not polygonal.

I had a similar issue with Wolf polymer 9mm. It was given to me and I figure what the heck, I'll shoot it...never again! Had to hit the slide of my hi power with a plastic hammer to free it up. Your gun might not have fully seated the round like mine and shooting it out wasn't an option. Don't know if it was sized correctly or what but when I sugested that it was the coating it caused such a sh*t storm here that I won't sugest it again, even though I think it was the problem.

I was shooting lead so could that be the problem. Didn't realize I wasn't supposed to. I've only put about 100 rounds of lead through it, so, hopefully, I didn't mess something up.

Try doing search for "Glock+lead" and you will find out you didn't break a thing.

[edit]
If your gun even has polygonal rifling in the first place. 8)

A round whose neck diameter is larger than the chamber will properly handle will do this. It's rare in factory ammunition, but sloppy hand loading can make many things go wrong.

Don't trust your calipers; they're not your chamber. If you're shooting hand loads, every round needs to be dropped-checked in your chamber. They should drop fully into the chamber with a "ker-plunk" and fall freely out of the chamber when the barrel is inverted.
