Please help diagnose my Glock issues

[ojisan]

I find it ironic that Glocks have developed feeding problems over the years as their whole claim to fame was reliability.

At the time of Glock's introduction, hollow point ammo was in its infancy and many bullet profiles did not feed well in any guns.
Ejection and extraction was not a problem for any maker, just feeding.

The earliest Glock 17 9mm had a very deep feed ramp that while assuring feed reliability, left much of the case at the rear unsupported.
Magazine tests of the day reported badly bulged and stretched fired brass that was not suitable for reloading.
Glock's explanation at the time was this was a military design gun, made to shoot factory fresh new NATO ammo one time and one time only, as the military does not reload handgun ammo.
This is one of the reasons that Glock did not recommend reloads in their guns....only new brass should be used to reduce the chance of case failure when firing.

Glock kept going with this unsupported case design until the .40S&W came out, at which time many kabooms occurred.
So, Glock now has had to go with a shallower feed ramp and more case head support....and now they are back to the same feed problems everyone else was having 20 or so years ago.

Get some full power ammo.

Makes sense, but why don't other current brands/models all suffer from this problem? I will say our 9mm 1911s may not initially have fed FP coated lead the best, but my first H&K (P2000, 9mm) feeds, fires, extracts,ejects everything: Freedom Munitions FMJ reloads, my own soft loaded 1.11" coated lead FP and defensive ammo.

I would think it always best to get all the factory "gunk" out of there and lube as required, but I don't know glocks. I don't think what the OP is experiencing is acceptable and how strong a grip to you need on a 9mm to get it to cycle?

I would pull mags apart I had 2 Factory came with gun and 2 that didnt Glock mags and they had a tab on the inside from the mold process all 4 had it and would hang the spring up and very hard to get a handle on because it wasnt consistant. Finally just took everything apart and when I took mags apart went to pull the spring and they would hang up as the spring was being pulled out.

Brief updates:

The followers are 2183-2s.

I left the gun locked open for a few hours, then read some FUD on a different forum and closed it again.

Still haven't charged the mags. Have 2 more coming from Brownells. I agree that I'd like to get some Gen 3 mags but I'm not sure were to get them anymore. This gun shipped with two Gen4s.

When I get a moment I'll compare the two mags by putting their feed lips right against each other. Should at least surface any obvious discrepancies.

I haven't gone looking for heavier ammo but I will.

Before buying the G17, I tried the range rental version. I fired 50 rounds through it and had one of these failures. However, when I went in to buy my new one the people behind the rental counter said that G17 had finally broken down. Unsure what to make of that. Also, the ammo they handed me was a box of Sellier & Bellot, though of course I forgot to check the bullet weight.

At the house, I have taken it out of the safe and fast-racked the slide a bunch of times on several occasions. It's hard to do as I am spending the entire weekend around small children and I don't want my son asking questions until he's good and ready.

Your issue is you bought a glock instead of a Sig

The 226 on sale in Cali has a mag disconnect! No dice.

[Douglas Munro]

any updates?

[Doctor Suarez]

Haven't been able to shoot it again. Small kids and a full time job and the Destiny expansion. Will wring it out again either this weekend or the next. Thanks for asking!

Glock changed some parts to MIM and changed the angle of the ejection port causing some of these issues. My pre-2007 Gen 3 does not have these issues.

As others have said, keep shooting it, it may need to break in. Keep the grease on the slide or re-apply it if you cleaned it off.

Although its rare to have these issues on a G17, I had major issues with my G42 of which earlier models were known to have some issues. Mine wasn't one of these earlier models but I experienced everything you are experiencing but much worse. I cleaned too much copper grease off in my first cleaning and was having FTE's and FTF's every 2-4 rounds with Blazer Brass. Remington UMC would fail every 6-10 rounds.

I'm not blaming the issues solely on lack of anti seize grease, but after that first session I cleaned the gun and re-greased the slide rails and cam and continued to shoot it. Failures reduced but were still occurring at least once for every 20 rounds for the first couple hundred rounds. As I approached 800-1000 rounds failures became much less common. After approx 1000 rounds I gave it a full cleaning and did not re-grease the rails. Since then I have put over 1000 additional rounds through it without a single failure.

Now the G42 was known to be sensitive and have "un Glock-like" reliability when new on some units. A G17 should not have these issues. With that said, every unit is different. I recommend making sure you have enough anti seize on the rails and cam and make sure you are not over-lubing it. Then try different ammo and shoot the hell out of it. It may just need to be broken in like my G42 did. If there is no improvement over the next 200-500 rounds contact Glock.

Glock? Issues??? That is an oxymoron! !!!!

Glock lap boys not entering a Glock problem thread to tell us all how great that pile of S is. = Oxymoron!

Whew, okay. It took me a REALLY long time to get back to the range, since I have small kids and my beloved Mets gobbled up my entire October. But I have good news to report!

The Glock worked flawlessly. Unlike last time I lubed the weapon aggressively rather than relying on the copper lube and I added a Hogue grip. As a result, the gun worked flawlessly and I shot it so well I actually shocked myself.

The only issues to report were that the slide failed to lock open at the end of two mags but I believe my thumb may have been the culprit. Aside from that, feeding and ejection were smooth and I shot some of the better groups I've ever fired.

Thank you all for your help and concern. I think the useful lesson in all this is that relying on the copper anti-seize to start might be an okay thing to do but reliability issues are a possibility. But with the proper lubrication the pistol will work and work well.

EDIT: I should add that on a couple of occasions when I couldn't take the gun to the range I did what some suggested and simply racked the slide hard as I could over and over again. I don't know if it helped but it was part of the regimen.

EDIT 2: Just to brag...
