I have a brand new Glock 23 Gen 4 (.40cal). I've only put approximately 300 rounds through it and about every other magazine, I'll get a jam. It's usually one of the last rounds in the magazine. It didn't do this the first time I took it out. So I plan to clean it really well and see if it does it again. Fortunately, I bought it from a place that offers a lifetime guarantee (for $20). But it's a Glock!!! It should NEVER jam!!!! My other Glock has never jammed! My question is, if it keeps doing it, I know they'll want to try to "fix" it first. Should I just insist on being given a new gun? Also, what are the possible explanations for this type of malfunction? Thanks!

I've got a gen 4 Mod. 22 that I've owned for about seven months. I have never had a hiccup with any ammo I've shot. The only thing I had to do with mine was drift the rear site a little to the right and learn the trigger better. Other than that, it is my go to gun for CCW when I can wear an shirt over my tee shirt (Been a lot of 100 degree days here this year).
But, I do clean every gun and oil it right out of the box, no matter who makes it. To many times have I found if I don't, there may be a sliver of machined metal or just plain stuff that comes from a Monday or Friday run on the line.

I agree with X-Rap. This is almost always a magazine issue.
If you identify the problem magazine, then THROW IT AWAY. People try to fix bad mags, and it's more trouble than it's worth. Besides, Glock mags are cheap.
Oh, yeah, do not sell it to someone, either.

Send the mag back to Glock if you determine that to be the problem.
Try some different ammo. It should eat anything but sometimes ammo can cause problems.
Oh, and if you can't figure out what's wrong with it and just figure that Glock's suck, I'll buy it from you for $20.

Sorry for your luck, I'd also look hard at the mag(s), tear them down and put them back together, I've only had two issues with semiautos and both were magazine issues.

I agree with the majority. It is most likely a magazine issue.
More than likely its is your mag, sometimes the followers will have a little flash left on the follower from the molding process disassemble the mag and check the bottom for any burrs some fine grit sandpaper or even an emory board can knock that off really quick. when reassembling shoot a little CLP in the magbody and wipe dry and it should work well. If this doesnt fix the problem send it back to glock.

I will also agree it is more likely to be a mag issue.
Are you using any older mags or only the ones that came with the new pistol?
As posted, mark them and see if the problem is specific to one mag. If so, keep that one to practice your malfunction clearance drills.

I had some problems with my Gen 3 Glock, where the last round in a mag would go nose up, case wall on the feed ramp. It happened twice. In doing some research, it appears that Glock made a change to the internals of a mag which increases feed resistance. Glock 23s also use Glock 27 (subcompact) mag springs in their oem configuration.
The oem spring is underpowered, it is a compromise to fit a 9 round mag and a 13 round mag at the same time. Then Glock went and made an internal magazine change which further compounds the inedaquacy of the spring. I switched to Wolff extra power mag springs in my G23 and have had zero recurrences in over 600 rounds. Replace your mag springs with Wolff and don't look back.

Hicock45 has a couple of misfires here on this video with a Glock 26, 9mm....
I believe he is using re-loads, but that should not matter....

Forgive me if I'm missing it (wouldn't be the first time), but I just watched this video through twice and didn't see a single misfire.

Glock has been having extractor problems starting with their Gen 4's and in the last year beginning to appear in Gen 3's due to a switch from a forged extractor to an MIM manufactured one. This is a known problem and magazines do not affect it in any way.
Apex tactical is working on a fix for the problem and should be releasing it soon.
Some good basic background info and video of APEX's testing here: http://10-8training.blogspot.com/2012/07/apex-tactical-glock-extractor.html

You can't be serious.
Anything made my humans can and will fail.
This is why we practice stoppage drills.
You do practice stoppage drills, right?
You can insist all you like, but Glock will not give you a new pistol if they can fix the one you already have.
You wasted that $20!!! All Glocks carry a lifetime warranty, whether you're the first or fiftieth owner. Whatever's wrong is something really simple. Could be that the ammo is too weak for the strength of the recoil spring, or it could be a mag spring problem.
How, and with what are you lubing?
So if the first letter in the serial # of my new gen 3 g26 is "R", this means I have a MIM extractor?
Isn't MIM supposed to be an inferior process to forging/machining? Did they have any reason to start doing this other than lowering the manufacturing cost? Just wondering if this is something I should be concerned about with my new Glock.
Also, is this something that was done temporarily by Glock, or are all current production Glocks being shipped with MIM extractors as well?

I would be surprised to find if the Glock extractors were ever anything but MIM. The biggest problem MIM has is companies making MIM parts by simply sending a CAD file to the MIM vendor, when that part was arrigianlly machined. Injection Molding has special requirements, and MIM is weaker that machined steel. However if the part was desigened as a MIM part from the start, it should be fine.

True; but shooters with extractor problems should be experiencing failures to extract or erratic extraction, not failures to feed. Sounds like the OP has magazine troubles.

Extractors can cause failures to feed if the gap between the breechface and the extractor is to tight.

Without a doubt.
All I'm saying is: While some folks are indeed having trouble with the Gen4 extractors/ejectors, most often people having the problem he's describing, will find it was a magazine problem.
I have two Gen4 Glocks and they both threw cases willy-nilly for the first two or three hundred rounds, and calmed down thereafter. Neither has ever had a failure to feed of any kind though.

I have two pistols, one in 9mm and a Glock 22 gen 4. While the Glock hasn't failed me yet, ~600 rounds down the tube, the Astra (9mm) has had issues with the magazines, that oddly enough, went away after using Remington UMC and WWB NATO. Doesn't mean I'll trust it in a life or death situation, but it's reliable (for now). Still have to find replacement springs for the magazines.
That being said, and like it has been brought up before, anything made by man will fail at some point. I've had all the practice in the world with my Astra. Now I have a Glock, and now I know how to clear malfunctions.

Call Glock. They will email you a prepaid fedex label. Let them fix it on their dime.

Just curious, did you give it a good cleaning and lubrication after purchasing it?
