Glock and ammo

[Malamute]

I would be concerned if a defensive gun choked every 600 rounds.

The reliability question is valid. I dont think the real question would be "all glocks only run some percentage of the time", but that some guns dont work all the time. The common forum comments about "MY gun has run flawlessly for 600 rounds over the past 4 years" as if thats a statistically relevent event dont really add much. (one gun that had repeated problems is more relevent I think) One gun, and that small a number of rounds is a drop in the bucket. Some people will shoot 3 times that much in a weekend class, and some people simply shoot WAY more than others.

Glock do in fact have some known, occasional quirks that sometimes are fixable, and sometimes glock cant even make them run right. Thats just life.

I notice when people comment about several hundred guns their department uses and had X number of certain problems in X number of average rounds through them.

I handload 9mm 124 gr. plated, and my G19 operates better with loads that run to the heavier side.

By the way its a Gen 4 G23 about 3 years old.

If this were my gun I'd be on the phone with Glock CS to find out if the gun has the latest ejector and or Dual Recoil Spring Assy.

I would be very surprised if it was truly a barrel twist rate issue.

It is a fact that some guns just dont shoot as well with some ammo as another identical gun. I dont know if anyone has ever definitively stated exactly why that is, but it seems a constant.

Could be, but it was odd. I would shoot 147gr Winchester Train and have sub 2" groups, switch the 124gr WWB and have 3-5" groups, same distance, same gun. Very Strange.

Need to know more about the type of extraction failure.

But you can try another extractor and ejector. I also don't like WWB. But Federal and Blazer should be GTG in a Glock. I also run a SS recoil rod with the stock springs.

I have shot the white box ammo 115 gr. in my Glock 17 gen 3 with no problems.
I shot mainly my reloads Berry's plated 124 gr. with out any problems at all.

The last 1000 rounds through my G17 and probably last 750 rounds through my G19 have all been my weak reloads (3.5gr 700-X running just a shade under 1000 FPS), and no issues, don't really think it's an ammo power problem.

I use Winchester white box in my full auto UZI and it runs great . The UZI requires hotter ammo because the bolt is so heavy moving it back-and-forth with Remington and federal it runs so much slower. I like it.

i exclusively use wwb in my centerfire autos. never had a failure. always cycles, in all of them. i've had crap luck with winchester .22, though, i wont buy it ever again. glocks i use it in are a g26 and a g30.

I still have a bunch of WWB I acquired over the years, and have shot a good bit through my Glocks, and a few other things. Never really had any issues with it, but like anything else mass produced, eventually, you will get an occasional problem now and then if you use it long enough.

Just curious, but have you stripped and cleaned the slide on your Glock lately? It needs to be done as part of routine maintenance, especially if youre shooting it a lot. I do mine a couple of times a year, and its usually pretty cruddy, especially around the extractor. I usually make it a habit to flush it with Gun Scrubber in between tear downs, and I still get junk flushing out.

I have a bunch of Glocks, all Gen 3's, and the only time I seem to have had issues with extraction, is when my brass starts to wear out. I shoot the brass to failure, and the rims get tore up from repetitive extraction, causing problems towards the end of its life.

I finally figured this out, after replacing an extractor, back when there was a flury of complaints going around on the web about BTF, claiming the newer extractors were the problem. When I switched it out, and it still continued, I suspected it was something else, and my brass was the only suspect left. I actually used WWB to prove it. The gun ran fine with factory, and had troubles with a known, well used lot of my reloads. Back to factory, and problems went away. Swapped the extractor back out for the old one, same thing. The old extractor is still in the gun, and working fine.

I cycle through about 6000 rounds of brass on a repetitive basis. Some older, some newer, as its replaced. As I said, I shoot the brass to failure, which is usually indicated by the increasing number of split necks, stove pipes, and occasional cycling issues. The one real advantage to this is, it allows you to realistically practice IAD's, as they happen randomly, and unexpectedly. You dont have to set them up, and never know when they might occur.

2. The 100% reliability of Glocks are exaggerated. What Glock users really mean is 99%...when they say their Glocks work 100%. And this would mean my experience of 1 failure to eject per 600 rounds is normal..

Nothing is "100%", and Id say most things are probably around 99% these days (not counting the break in required with some models, if needed).

The Glocks are no different (and right out of the box, no need for break in), especially if you feed them the right ammo, and maintain them.

Of all the different models I have or have owned, the Glocks are are one of the few, that fall into a group that have worked out of the box (simply load the mags and shoot), with very few, if any issues. HK and SIG are the others.

3. Or...maybe its just me... limp wristing every now and then.

I doubt it, unless you normally have the issue. The limp wrist issue has nothing to do with "the wrist", and is usually an issue with those who are novices or unfamiliar and/or fearful of shooting. It occurs when you allow the gun and your arm to recoil rearwards with recoil.

As long as you dont allow that, and keep mass behind the gun, they will run, even with "no grip" at all.
