Striker fired v hammer fired. IMHO - hammer fired only. Why striker fired? Cheaper to manufacture.

MasterBlaster - O'Toole's comment on Murphy's Law said "Murphy was an Optimist."

Saying it is simply mechanically impossible is too much of a reach for me. I'm waiting for the OP's reply from Glock.

I don't expect Glock to ever admit that this is even a remote possibility. I recall that many moons ago I had firearm randomly go into burst-mode on me. I returned it to the manufacturer with all of the details I could provide. It returned fixed, with a one-line note stating that they had replaced a certain part. However, that part wasn't even remotely related to firing, much less burst-mode capability, in any way, shape or form that I could fathom. I thought that was both funny and telling about what a company will admit to.

seems like I got here late....I've always believed that any time an AD/ND occurred it was because someone pulled a trigger.....regardless of what their story was ! If I believe the OP then this would not be possible in this case, so..............
I think taking it to an independent pistolsmith to examine is the correct choice. Glock will NEVER admit a flaw in design or anything else that detracts from their "Glock Perfection".
Neither will most Glock owners......It just seems strange to me that so many people refuse to believe a mechanical device can fail........ANY mechanical device, even a Glock can fail !!!JMHO

Also agree..
It didnt help matters either that the OP chose to leave out pertinent details and then get upset about the comments, especially with a tardy return.

I carry glocks and 1911s. I've ran "scientific" tests on the trigger by throwing a G17 in the air high above my roof line, racked(round not chambered!) and dropped on a very hard surface 6-8 times. Trigger never disengaged, it still went "click" My scientific test did beat up the surface of the G17. It's a Glock it still works!

Bad Glock Action

I own a Glock 36 (45 ACP compact single stack) originally purchased for my wife.
It had an atrocious trigger.
Everyone who tried using this handgun frowned and complained, me included.
This is a common complaint with Glocks (i.e. The Infamous Glock Trigger).
I purchased aftermarket parts to install and was only marginally successful in improving the action. There are those in the land who take it upon themselves to re-engineer and modify the geometric relationships in the firing controls to improve the action.

In your case, I believe that the action was improperly modified and since the Glock striker is partially cocked with a live round in the chamber, I suspect the worn/modified sear engagement surfaces let go...BANG!

Were I you, I would send the pistol back to Glock with a description of the "accident" and let them restore the pistol to "as delivered condition".
Don't chop it up. Save it for a "tool box" or "fishing tackle box" firearm.

It has long been known that switching from one action to another under stress can be fatal. Put the 1911 back on the dresser.

Parts can be purchased from the Glock store if you want to play with it yourself.

I know of several documented cases where a striker fired pistol fired while being carried in a holster or a pocket. One fired while being carried in the inside breast pocket of a leather jacket while the owner was riding a motorcycle on a highway. He survived. None of these guns had been modified and no one's finger was on the trigger. I will never own a striker fired pistol.

As someone who has only been into handguns for a few years and carries a Glock pretty frequently and has one on his hip right now, that truly concerns me.

Drail, Iím not asking you this to argue or because I donít believe you, but because I genuinely want to know - can you point me to the links to these stories, if theyíre available? Everything Iíve ever read seems to indicate just the opposite, and itís hard for folks like me to know exactly what to think. Thanks!

Details aren't complete on this instance, but the article says they believe it was a G43

That was extremely difficult to watch. I have a G41 with a professionally modified trigger. I do not carry it but I do leave it loaded. I am reconsidering that.

The Glock is a pretty safe gun. If I were picking a gun to throw against the wall and not have it discharge, a Glock would be one of my top choices.

On the other hand, in spite of Glock's literature and what the ATF says, the Glock safe action is a whole lot closer to a single action than it is to a double action. As safe as the gun is, it is still really a single action gun, with a short, light trigger pull, and without a manual safety.

I don't think the OP's issue is a particular Glock thing. For his gun to go off without any human involvement indicates a gun that has something wrong with it, and it not to Glock factory specs.

I would throw a V2 HK that's decocked and on safe into a wall before any other gun.

On the topic of leaving things loaded I have over 125 guns and I leave none except the revolvers loaded but all have full mags of defense ammo. I don't want a fire/any sort of accident causing anything to fire but the revolver are slow to load so I compromised by pointing them all at a 1/2 inch plate inside the safe.

Any body have any actuall proof that a round can be ignited at half cock? Mechanically 2 things should have to happen to fire in this situation. 1 being the striker slipping off its engage ment surface at half cock. 2 a complete failure of the striker block. As in it's not there at all or stuck up enough to let the striker pass. Plain and simple that is the only 2 parts that could have failed. I'm sorry but for that to happen that thing must be beat to crap or modified or just plain broken. It is impossible to happen if your parts are in working order. I will say that again. Unless parts are broken or so worn out they cant do there job. This can not happen. I would really like to see some one firing a round from half cock. I could see a light primer strike igniting later down the road. But that was never mentioned.

No S&W double action revolver EVER fired by itself nor have I ever heard of, nor can I imagine how a 1911 WITH HAMMER DOWN, could fire on it's own. Those are my two GO TO systems for carry or night tabe or to hide an extra in the cat bed...have been for seventy years. No plastic.. no gizmos... no gadgets... just common sense gun smithing and assembly. CUT THEM ALL UP before someone hurts themselves with a wonder shooter-proof 'safety' gun.
Cut up my Glocks based on the claim the OP made?

Lying sack of crap Washington Post reporter Jack Anderson claimed in 1986 that Quadaffi Duck was buying bunches of Glocks for terrorism purposes because they could not be detected by airport metal detectors or xray machines. Do you believe that claim as well?

Maybe we should just cut up every gun of any model that someone makes a derogatory claim about. Do it for the children!

This thread has me worried. I have a .40 Glock in my safe, fully loaded and ready to go. Maybe I should unload it? I don’t have a cat, and I always felt that my safe would protect it from mishandling, but now I know that Glocks can go off when left loaded and unattended.

Anyone genuinely interested in the armorer's findings can PM me. This is a concern to all but more of a concern that I would have to PM OP as this is now been dropped in every ones lap.

Not sure it applies to Glocks but Cooper once described a phenom' known as "Tolerance Stackup" in a 1911. It's when after firing or loading the parts all end up in the worst possible position-sear barely engaging the full cock ledge on the hammer, etc. Of course this would require some play in the mechanism due to wear or improper fitting. But don't see how this would affect the striker block. And don't see how the gun would go off while lying on a table instead of just doubling when the slide slammed home while loading.

That combined with the fact when a Glock has a lot of rounds the tolerances start to drift and you can start to see out of battery ignitions and strikers slipping off the "sear" if the slide has vertical play. Normally the firing pin block will prevent this from happening but if it is not working like I described you can fire the gun by sticking a screw driver between the slide and frame and twisting.


The striker is solid steel. The block is solid steel. The slide is solid steel. In order to break a factory block or striker you would need to put a freeking ton of rounds through it. You prying up on the slide to make it go off proves nothing. I can bash the hammer down on my 1911 with a real hammer and make it go off. What's your point Still waiting for proof a round can ignite at half cock. And if the gun has bein shot that freeking much that the parts are so worn out that they are complete failing. I would call that negligence on the gun owner for not replacing the firing mechanism befor it becomes dangerous.

By the way the glock is easy enough a 5 year old to replace all parts. No excuse to have parts that worn out.

I'm calling bs some one tweaked on that gun. If those are factory parts I'm just not seeing it.

If your question is simply if there is enough energy for the partially cocked Glock striker to fire, there is this in post #18

Quote:
The partially cocked Glock striker has enough energy to ignite primers.

From the guy that invented the Glock Striker Control Device (SCD) or Gadget ( https://taudevgroup.myshopify.com )

I borrow this quote

https://pistol-forum.com/showthread....your-EDC/page9

Quote:
I think a lot of people are putting too much emphasis on partially tensioned vs. fully tensioned strikers. The Glock isn't safe because it has a partially tensioned striker (the partially tensioned striker has sufficient energy to detonate most primers) but rather due to the features of the "Safe Action"ģ system -- features that can be (but seldom are) completely reimplemented in any striker fired design -- that form redundant "safeties" that require multiple "failures" before the gun can discharge.
If you are referring to any other safety features of the Glock allowing that partially cocked striker to ignite a round, that is an entirely different question, and something we're hoping the OP can answer once his gun is inspected.

The plunger spring is a tiny coil type one. I'm getting tired of explaining this

Ummmmm I never said it was not coil spring. And pretty much every modern pistol has some type of firing pin block run by a "COIL SPRING" once again what's your point hell even my old 45-06 has a coil spring firing pin block. My 1911 has one. My cz.75 has one. My beretta has one. So what you are saying it's the springs fault? Hammer or striker fired are subject to the same firing pin block failure.

It's very easy for it to seize, fire 2500k suppressed rounds in one day and let me know how freely it's moving vs when you first checked it. The spring also tend to break much sooner than other parts that would prevent the gun from working like the extractor spring for example. Other guns use much better systems to prevent that from happening in terms of spring strength and coil diameter or in HKs case a steel wire spring instead.

I'm saying that if you have a police trade in Glock like the three I have/had stuff can be worn that it can be unsafe and once again because of how the gun works you will not get a warning of this happening. On a CZ75 or 1911 or SIG 226/9/0 the hammer will follow if the sear or hammer surfaces are getting dangerously worn. The Glock will just wear out and you won't know it until it lets go or you drop it since most people don't inspect them.

Berettas don't rely on the spring to return to safe as much, if you haven't noticed it gets lifted against gravity to fire and it's also again way easier to check since you can just turn the gun over and see if it works.

It can and does wear out and I have seen dozens of shot to unsafe guns of every single make/type, nothing is immune to it and I've personally already shot three guns to that point with over 50k on each that required repair.

Why is this so hard to understand that things can and do fail if worn out? The OP even said it was a used gun and that he doesn't know how to inspect it, I'm not surprised at all there was an issue on an unknown state gun. I've bought used guns from WWII that would most certainly fire unintentionally in the state they were purchased in, had to be fixed. Doesn't mean anything was wrong with the design just that they were beat to hell

Lastly you are wrong, the striker system is more reliant on the FPB than any hammer fired gun. The 1911 is even less reliant on it mechanically than others
