Glock Failure to Feed

[ShaunSweeney]

Hi Guys,

I'm at a loss here. I have onwed a few Glocks in the past and never had an issue like this. I have a G17 that will not feed steel case ammo reliably. I have done the obvious like full teardown and cleaning. It was pretty dirty when I bought it. I have also replaced the recoil spring assembly with a factory Glock part. I have polised both the feedramp and breech face. I have also replaced the mag springs with +10% wolff spring and the followers are #6.

The gun will feed brass case about 99.9% reliably but steel case about 60% reliably. The round will chamber almost completely and the slide can be smacked to fully chamber the round. Of course this is not the proper way to fire a pistol. Any ideas what may be causing this?

re: failure to feed

I had that problem with my Sig using the Wolf steele cased ammo. Problem for me was the laquer coating on the steel case would get hot and start coming off, effectivley shrinking the size of the chamber. Rounds wouldnt seat correctly. You have 2 options. Clean the throat and breech face every 20 rounds or so, or dont use the laquer coated ammo.

 

[ShaunSweeney]

I don't think this is the issue as I can immediately run a mag of brass case w/o cleaning. The brass will feed flawlessly even with steel case ammo mixed in. I have even shot with a mix of brass and steel in one mag.

do you have a chipped or damaged extractor?

 

[newportri]

Do you have the original barrel or a replacement barrel with a possible tighter chamber? I Are they both the same type of bullet (RN, HP, etc.)? Have you measured the two different ammo and seen any differences in for example diameter of the case?

Could the ejector or the extractor, if bad they can slow the rate of the side down and cause a feeding problem. The steel cased ammo in general isn't the best but Glocks should be able to shoot anything. I shoot almost nothing but steel from my Glocks and have no issues. They do wear down your extractor and ejector faster. If its an older gun or its had a ton of rounds through it, doesn't hurt to do a full over haul.

Glocks should run steel case with no issues. Were any other parts altered with? I would recommend either shipping it to Glock for rebuild or replacing all springs yourself/taking it to an armorer for inspection/spring rebuilt.

Send it to Glock via an FFL, get it fixed, and be done with it. It will magically come back without any problems. (Or at least, that's what it's been in my experience.)

I might have an extra extractor laying around if you would like to try popping that in.

Do this. + while it's there get it refurbished and it'll come back LNIB.

 

[newportri]

If you drop one of the trouble rounds into the chamber, does it drop right in, or is it tight?

 

[ShaunSweeney]

The barrel is the original. The rounds drop in smoothly.

The extractor appears to be fine.

I have replaced all of the springs in the gun except for the mag release.

I really don't want to have to send this to glock as I have no ten round mags to send it in with.

 

[ShaunSweeney]

Here are a few pics. The OAL of the steel case is definitely shorter than the brass. For some reason my wife's SR9 has no feed issues with it.

Why would you send them ANY magazine? Unnecessary. That's like bringing a mouse or a keyboard to a computer repair place. They don't need it unless the mag is part of the problem somehow, which is doubtful.

[newportri]

That looks like aluminum, and not steel. I don't blame you for not wanting to ship it, since that's expensive. If it works with brass ammo, I would stick with brass and not bother with aluminum.

It is definitely shorter and it's possible that the round is being pushed down too far before it hits the feed ramp (it doesn't enter straight). I had a similar problem with my 10 round glock magazines when I used Berry's 124gr hollow points, but it would actually hit the feed ramp and not feed at all. I noticed that I could push down on the magazine follower so it would tip down. It's supposed to be pushed straight down and not tip. I took out the magazine spring and stretched it out a few inches to make it tighter and put it back in and I have not had any issues since then. You might want to give it a try since it won't cost you anything.

 

[ShaunSweeney]

It's definitely steel. The ammo is wolf. The mags are good. I replaced the springs and the followers are #6 and push down level. I think sending it to glock is unfortunately the ultimate solution. For some reason I thought they always wanted the mags to ensure they were not part of a feeding issue. That's good news that they don't. I will call them on Monday.

It's not expensive if you use an FFL to do it. The last one of these I had done actually cost me nothing, (The dealer I use paid for it, because I bought the gun from him) and the couple before that only cost me about $25 each time, and that was the cost of USPS shipping plus a little markup for the shop.

You can get your gun fixed by Glock for the price of 2.5 boxes of ammo and a week or two of waiting.

Don't bother even calling them, they're just going to tell you to send it in. Just use your favorite dealer (the one your on the best terms with) to send it in as a repair, and write up a description of the problem. It will come back to the dealer working, and then you just pay the dealer whatever they charge to send it out and back. It goes in and out of the dealer's book but since it is a repair there is no 4473 required, unless the frame is cracked or something like that.

ETA: If it malfs with all the mags you have its unlikely its a magazine issue.

Thanks for the input guys. Looks like I'm off to four seasons on Monday. I'm going to miss my baby.

 

[andy t]

They are closed on Monday. And it's not a baby, but a tool...

[ShaunSweeney]

Damn that's right. Well Tuesday then. And if I say it's my baby then that's what it is.

 

[ShaunSweeney]

Sent it out yesterday. $30 for shipping in case anyone was wondering what it costs these days. Hopefully this solves my issues.

 

[squeeze]

It's hard to see clearly, but it looks like the rim on the steel case is taller.

 

[ShaunSweeney]

I brought the SR9 out the other day to make sure it wasn't the ammo. I was pretty sure it had no feeding issues with this ammo and low and behold not a single malfunction. Something is definitely wrong with the Glock. Hopefully they can figure it out.

this was helpful, thanks! i need to send my g19 in for another issue and was thinking to use FS.

if you could post up on how you make out, return times, and overall experience that would be awesome.

 

[ShaunSweeney]

Glad I could help! I will keep this thread updated until the issue is resolved.

 

[ShaunSweeney]

Still waiting for it to return.

 

[Acme.Armament]

Still waiting for it to return.

Did you just ask for a repair or repair and refurb? Refurb can take up to 4-6 weeks and you say that you sent it on 12/21? It hasn't been three weeks yet and there were two holiday in this time. Be patient.

 

[ShaunSweeney]

I sent it in for repair only. I'm not being impatient. I didn't want people to think I forgot about the thread.
