Glock fatal design flaw?

I was at my the local range today, a facility that lets newbs off the street buy ammo and try shooting guns, when I heard a conversation between two RSO's and a few customers about GLOCKS.

The RSO's contended that GLOCKs aren't all they're cracked up to be - citing the fact that their range GLOCKs frames generally crack within 6 months and need to be replaced and that the hype behind them is all a big advertising blitz.

That got me thinking, since the person that got me into handgun shooting told me that GLOCK, for it's simplicity, reliability, and durability was the best choice of gun for a new shooter, him personally citing hundreds of thousands of rounds fired through his G17. Since then, I've heard stories of GLOCKs with upwards of a few millions rounds fired through them without a problem.

I myself have had my GLOCK for a few years now and put between 10000 - 15000 rounds through it and besides some of the springs feeling a bit broken in, it shoots fine.

Then it hit me, the GLOCK does have one major fatal design flaw - new shooters.

The slide on the GLOCK is much heavier than the frame and there are only 4 major points of contact connecting the slide to the frame (the 4 metal rails, embedded into it, two around the front of the trigger, two towards the rear of the gun).

I have no doubt that a GLOCK will survive extreme climates, submersion in water, or it's action jammed with sand or flour - but when you consider the design, the biggest weakness the GLOCK has is constant use by people who don't know how to shoot handguns.

I theorize that because the slide is so heavy compared to the frame, because the slide doesn't form a perfectly tight seal with the rails (I don't think any gun does), and because the points of contact are small, that limp wristing causes the slide to vibrate vertically, up and down, in a fashion that the gun was not designed for. With enough of this vibration, over time, the points of the frame (where the rails are attached) weaken and eventually crack.

I think this might explain why public ranges that use GLOCKs have them break so often, but also why competent operators are able to get great longevity out of them. We all limp wrist from time to time, but I think experienced shooters do it more rarely. New shooters almost ALWAYS limp wrist.

The analogy I'm thinking of is like driving standard. You can drive in first gear everywhere you go, but it won't take long before your transmission fails. I think GLOCKs in the hands of limpwristing newbies are the same way. This might be a problem if you're constantly lending your gun out to inexperienced folks, but if you know how to shoot, I think you should be fine.

I assume this is an inherent flaw with all semi-automatics and justifiably other guns hold up better than others - but I think the GLOCK bashing that goes around sometimes is ignorant and uncalled for, as the problem itself lies with the shooter, not the gun.

Thoughts?
 
It's possible. I know of a case were the slide rail cracked on a buddies glock. He had 10000+ rounds through it. It was determined that the heavy trigger pull was part of the problem. It had an 12lbs trigger. I don't know all the details, but apparently the extra stress on the frame from the heavier pull contributed to the failure.

I have a Glock and it has the 5.5lbs trigger. It is nice and easy to pull. I guess I'll see when I hit a few thousand rounds through it.
 
harbl, does your keyboard automatically switch to caps on when it senses you're typing the word GLOCK?

:p

Good theory, it would explain the discrepancy. I wonder if other range operators have noticed range GLOCKs have a shortened lifespan.
 
I'm on a bit of a caffiene high right now - and I read a wiki article saying Glock's trademark is "GLOCK"
 
:agree:

:eek: OH MY GOD SOMEBODY BETTER TELL GLOCK :eek:

Someone just found out that they break after 6 months, and that new shooters will break handguns by using the same ammo as experienced shooters.

Can't believe they managed to keep this a secret since they first hit the market in 1981. Glad someone finally spotted it.


:rolleyes:
 
I think a lot of people have spotted it, but not given a thought as to why it happens (just catagorically writing off the brand as crap).

If I recall correctly, Glocks primary market was individuals with some semblance of training and compitence (military and police originally, sports shooters later down the road, I thought).

Sorry about the sarcasm before, realised now it reads *aggressively* but that was not my intention.

Only problem with your statement above is that the average sports shooter is much better trained than your average LEO. Military are another story, but sidearms are essentially all about civilian police anyway.

Your average LEO puts down what, 300 rounds per year? Your average sports shooter will do that in 2 range sessions. So I'd be looking for this sort of damage from police ranges rather than civilian ranges. Just my $0.02.
 
Humm... Lets say the GLOCK (tm) shoots 400 rounds per day, five days a week for 6 month... that around 50000 rounds... How many rounds do these pistols shoot in 6 months?? Also, what caliber were those Glocks? Glocks in 9mm seem to last longer than .40, 10mm or ,45 according to rumours...

Anyways, if they break after 50000 rounds and you shoot 5000 rounds a year in your Glock, that's ten years before it breaks... Mind you, those receiver tabs are rather small and could possibly crack sooner if they are not manufactured right...
 
Actually, that's kind of an interesting point - there is a known issue with 40 cal GLOCKs (did I get it right???) with lights fitted, which would also seem stupid at first glance (unless you're the guys at GLOCK trying to figure WTF is going on) - it could be that there's something going on between the slide and the frame that is altered by grip pressure, or the presence of a light.
 
Here is my thought, limp wrist won't cause breakage but the poorly fitted 4 point rail do cause excess stress to a certain point of the flame and cause breakage. When I bought my g17, I look at several Glock and compare the gap between the flame and slide, I found everyone was different, some gap are more at one side than the other side, some have more open at the back of one side and more open at the front at the other side, that said some of the rail were poorly fit into the flame. I pick the best of the three and I am happy with the purchase. There are also a weak point on the glock flame which is the holes that the take down lever is. this hole leave a weak point on the flame because I have seen a lot of KB pics the flame broke at that place. Anyhow it is a very reliable piece for the money.

Hm. Interesting info about the Glock. What's not so interesting is the pig-headed bull about newbies. You'd think that nobody here had touched a gun for the first time, once.
 
...the average sports shooter is much better trained than your average LEO.

Very few sports shooters receive professional training in handgun combat, for hundreds of hours, on ranges with moving targets while learning to draw and shoot their weapon while sitting in a vehicle, laying on their back, after running an obstacle course, etc.

I was a sports shooter for years before I was a cop; however, I wasn't trained before I was a cop

... but then again you couldn't have convinced me otherwise before I was one either.

That being said... I've got thousands upon thousands of rounds thru my GLOCK with nary a problem except the odd part that wont pass an armorers inspection that has needed replacing.

It does get jammed up with donut crumbs now and then
 
Glock fail discussion...

You boys just wait until TDC gets home! :p

NAA.
 
why should we wait until TDC gets home? is he the all knowing gun guru on this site? personally I think that he thinks he is. i don't mean to harsh on him or anything but i read post, and he post a lot. giving info, and advice. but after a while of reading of what he writes he starts to get on my nerves. it just seems to me that he thinks he knows EVERYTHING, and he just may be but the way he writes things on this site he makes it seem that he's always correct and that everybody else is wrong. but even i have seen his mistakes, and i dont know a whole lot.

i don't mean to be negative but im just pointing out that for some reason you few guys seem think hes god.
but no hard feelings, all in all he seems like a great knowledgeable guy
