Very disappointing range day.

Well I took my new-to-me Glock 30 to the range today with some bad results. I have shot it once before, only 50 rounds though with no problems. The first time I was shooting Winchester JHP Silvertip 185 gr. No problems with those 50 rounds. Today I was shooting Winchester FMJ flat nose 185 gr. Out of the box of 50 I had 5 failures to feed. Not sure what is going on here. I really wouldn't think it is the ammo, but I have high hopes that it is.

The gun is a Glock 30 with a KKM barrel. I would have put the stock one in to see if that made a difference but it didn't come with the gun. It also has a 3.5 lb disconnector. I'm not sure what that is. Maybe it's the barrel or the disconnector. I have no clue. Maybe it's the ammo.

Can anyone shed some light on what the problem may be or anything I can check for? i know it's probably a crap shoot. I did clean It up very nicely just before I left for the range.

Thanks for your input!

Oh and a side note, but not as concerning, My new Sub-2000 9mm Glock version had a failure to eject every time on the last round of 200 rounds.

Go back to the winchester you used without trouble and try them again.

If no trouble, stay with that ammo.

I dont know enough about pistols yet to address your other questions.

Good luck!

That wouldn't satisfy me at all. I didn't expect this gun to be picky on ammo. IMHO can not be trusted at this point for self defense at all. This thing is going back in the safe for now. I'm going back to my trusty Mossy 590 for HD.

Hi Swede,
Did you try more then one mag ?? Could be a problem with a certain mag.
Also , the flat points can hang up on the barrel hood.

Gunfighter, You know it could have been a mag. I have 10 mags for it. I brought a couple with me. I didn't shoot enough ammo to really figure out if one of the mags was bad. I did a little research online and I'm kind of thinking that may have been the problem. So the flat nose can cause a problem as well huh? That is interesting. Maybe 1 more range trip and some more ammo will tell me what is going on. Thanks Gunfighter.

Im happy that there is a possible solution. I respect you Swede when you refuse to accept nothing less than a core diagnosis of a problem and a way to fix it pernamently.

Cheers!

Hi Swede;
I use nailpolish to put a number and my ID on all my mag pads --- helps when you shoot competition as to "whose mags are those" and helps when I need to replace a mag spring or malfunction.

I have had flatpoints hang up , not often but one brand did or I may have reloaded some with a short OAL. ------- for sure I remember that I would get a FTF , where the flat nose of the bullet was "catching" on the brl. hood -- the slide would be about 1 1/2" to 2" from being closed/locked in battery.

This is with 1911 type autos --- noy real sure about Glocks.

THANK you Gunfighter for wonderful idea about marking mags. That will definatly settle whose mag it is at the range.

THANK you!!! :D

Yup, this sounds like what was happening to a tee. Also I was just reading a post by a gentleman who says the Glock 36 will have FTF's with flat nose every time. Of course that is his weapon so who knows for others. My barrel may not be helping much either. I hope I get this resolved on my next range trip.

The one I had (no modifications) did not "like" straight-sided flat nose bullets. It fed ball and round-nose-profile JHPs fine. I like the 185 Silvertip in smaller .45s.

Swede ---- I hope you get it working up to 99.9% ---- wish I could say 100% but there is no such a thing with ANY firearm or any other man-made machine !!!!

I am also a "Note Nut " -- if I don't write something down , I am sure to not remember it . Thats why I keep a small notepad in my range bag. --- helps me remember if I had a jam on stage 3 or my # 6 mag is sticking on ejection etc.

I would not be surprised if it has something to do with the aftermarket barrel. I have a Lone Wolf 6" on my G20 and it does fail to feed a few times per 50. The stock Glock barrels have loose chambers that make them more resilient to ammo choices. Aftermarket barrels tend to have tighter chamber tolerances which make them easier on brass, but harder on ammo choice.

If you will be carrying this gun for self defense, I would invest in a stock barrel.

Ha I wish I could carry. I am in IL. Either way good call. I probably will get a stock barrel.

I had a similar problem with Winchester 185 gr. BEB (Brass Enclosed Base) ammo. Turns out what I thought was a FMJ design with a bit of a truncated nose, was actually exposed lead on the nose of the bullet. And the lead was not swaged, making it possible to catch on the feed ramp and at the breech of the barrel. Maybe the combination of flat nose bullets, the aftermarket barrel, and a few troublesome magazines all worked at producing the failures to feed. As a side note, I've never had a problem with Winchester 185 gr. Silvertips in any of my .45 pistols.

well, the reality is that it might be an ammo problem. That doesn't mean that it isn't trustworthy for HD, it just means you shouldn't shoot that ammo in it. Sometimes guns are a little picky. I would look at the mags too, but my feeling is that if one shot well and the other shot poorly, it is likely an ammo issue.

Now, with that being said, with rare exception I basically demand that all my pistols feed whatever crap gets thrown at them. I don't ask for or expect bullseye accuracy with every (or, really, any.) particular round, but I do expect them to function. The only exception to this is my little Kel-Tec. It works with the ball ammo I use to practice, and it works with Hydra-shoks, and that is good enough for me. Mostly, this is a matter of economy. I shoot what I can afford, and I can't always afford to buy premium ammo. It's also a matter of practicality. I want my guns to function through occasional bad rounds, Failure to fire excepted.

This is one reason why I like my Ruger P90 so much (and I am not saying you should sell your Glock and run out and buy a Ruger). I won't sell it because it works, man. It feeds everything. We had some reloads on the range one day that no one else's gun would cycle, and my old, ugly Ruger ate them up and asked for more. I have run mags mixed with ball, HP, surplus, premium and any other mix you can think of: Not a bobble.

And that kind of performance is what I look for in an "ultimate" self-defense gun. Don't want to hear about break-in, limp-wristing, recoil springs, magazines springs/feed-lips or being a picky-eater-just give me a pistol out-of-the-box that will shoot no matter how I hold it or what I feed it. And, yeah, they do make guns like that. The ones that come to mind and that I've experienced (there's no doubt more) are the aforementioned Ruger, most any "third generation Smith and the Beretta 92. They are my NO EXCUSES pistols.

Glock failures are 99% user error. It's extremely rare that a Glock pistol malfunctions. I never believe these threads without pics of a broken gun. I'll be more than happy to take that G30 off of your hands.

1911 failures are also 99% user error. :rolleyes:



With that said the magazine idea is a sound one. Any platform will have problems with reliability when a magazine is bad. This is actually a big problem with 1911's, every maker under the sun makes their own whiz bang mag for them.

I've actually had a Sig p226 fail to go to battery on me before, crazy right? It happens.

without the factory glock barrel, it is hard to blame the gun. Not ur fault either but a replacement barrel by another maker is not a glock barrel. Even though they say it will work yadda yadda, , you need to get back to stock and then pursue any issues after that..

If this were still a Glock that would be about right. However, this is a Glock with a third party barrel, a third party disconnector, and since it was bought used God only knows what else.

So my recommendation would be to make it back into a Glock and enjoy one of the more reliable pistols around.

Otherwise, you can enjoy the world of tuning and tinkering when you could be shooting. Nothing wrong with tuning and tinkering, if that is what you are into. I want to shoot. I don't want to play junior gunsmith when I could be shooting.

KKM barrels can be problematic. They are very accurate, but the tighter chambers make feeding an issue. I will echo the former posts and say to go back to stock or have the chamber reamed.

I'm sorry to hear that... nonetheless, you need the gun to work, every time. Try the stock barrel and move forward from there. I have 3 Glock pistols, none of which have ever failed even once with the stock barrels in place. They chew every kind of factory ammo too... from cheap bulk stuff, to the most exotic urban ninja loads.

Best of luck.

You make me laugh, and kind of ill at the same time. Thanks.

Well, if it was the 185 BEB ammo, I've seen it cause feed problems in several guns...if it was the standard 185 FMJ, then it "should" have run....in this case, I'd blame the aftermarket barrel....however, a FMJ with a round nosed profile will always feed better as it did with the SilverTips. The 3.5 lb connector wouldn't have anything to do with the feeding, just the trigger pull weight/feel...hopefully it's a factory Glock part but some of the aftermarket connectors work well also. Most people use the aftermarket barrels for firing lead bullets...some of them work just fine and even improve accuracy sometimes...but I have to recommend a factory Glock barrel for the utmost in reliability...and G30s are already noted for their accuracy from the factory ...;)
