Strange glock malfunction

Am curious about the "blocked slide" issue.

The more I think about this, the more I'm convinced that this is the only scenario that makes sense.

I have fired a Glock 10mm while intentionally blocking the slide with my hand and then with my strong-side thumb and was not hurt in either case. But I was doing it intentionally and I definitely felt it both times although I wasn't hurt. It's hard for me to believe that someone could fully block the slide and not notice it, but nothing else really fits with all the facts.
 
glad

Glad to hear that you have a grip on your ammo situation. I initially believed you might have no mags or spare ammo available to you in your rig. That is my fault for jumping conclusions. I once watched an officer with a revolver and 6 extra rounds, shoot at a crippled animal 9 times. With 3 left in the .38, she had to go back to the office for more ammo!

Am at this point at a loss for any explanation regards your failure to extract.
 
Detail strip and clean

I've been shooting Glocks since 1984. I'm a Glock Armorer. I've encountered more than a few that the carbon fouling built up in the extractor seat of the slide. Some were baked in and had to be cleaned out with a dental pick. Enough buildup will inhibit your extractor function. I hope this helps. Paul
 
UPDATE

Well the ammo came in and I ran it through the gun with no problems.

Went to range to qualify and did another 150 rounds or so with zero problems and one of the armorers tore it down and cleaned it. (We do have armorers but I work for the state so there isn't necessarily one available to me when I need one)

I even tried recreating the malfunction as best I could remember the shot when I was firing it on my own and nothing.

At this point I'm chalking it up to a defective round.
 
I think it will remain a puzzle

The only things that makes sense to me are:
  1. Something kept the slide closed so that it couldn't cycle,
  2. A marginal round was just powerful enough to put down a badly hurt animal might but powerful enough to cycle the slide part way -- but not far enough to make the fired round hit the ejector or to allow the slide to pick up the next round from the mag.
That second one is your conclusion: defective ammo. The "right" (or "wrong") load might allow that to happen. I've never heard of that happening, but there are a lot of things I've not heard of.

It sounds as though the gun is functioning properly. I wouldn't worry about it.
 
Yeah I'm a little more at ease now... though I'd still prefer a different sidearm haha.

We fired 50 rounds of our duty ammunition and no problems that I noticed. Though maybe I could blame that one round in the 4 ring on a defective round too :D
 
Was the muzzle of the gun touching the deer when you dispatched it?

Weird things happened. If you have something like that happen again go shoot some rapid fire. It will tell you if you have an issue or not.

Could be you inadvertently limp wristed it shooting 1 handed. Who knows.
 
Weird. I would suspect the extractor is gummed up. Just because a gun isn't shot, doesn't keep it from getting dirty. Strip it down totally, inspect for damage, clean and lube, reassemble and run a box. Should be fine.

If the extractor were gummed up, the slide should still have cycled, and stripped the next round and tried to feed it. That didn't happen.

About the ONLY thing that makes sense, if the shooter didn't somehow inadvertently keep the slide from moving, is an under-powered round that exited the barre, but didn't have enough force to fully cycle the slide.

Remember: the gun functioned properly later without any real intervention from the shooter.

If it did try to extract, but the slide didn't go back far enough to hit case the spent case to hit the ejector, and then came back forward, it MIGHT have either not fully pulled the case out of the chamber or somehow reinserted the spent case back in the chamber. (Nothing would necessarily cause the case to be pushed out of alignment until the slide goes much farther back.)

That really seems to be dependent on an odd set of conditions, but barring something that blocks slide movement, that seems about the only explanation that fits what happened.
