Guns, Bows, Shooting Sports, and Hunting Glock 17L problems

[Flying_gage]

As the title says I have a problem with a Glock 17L. Purchased brand new at local shop.

First day I put 60 rounds through it with the usual Glock performance. Felt good and performed as expected. Went back out the following day to dial sights in and out of 60 rounds had 30+ failures, mostly failure to feed but with a smattering of stove pipes and strangely 4 failures to go into battery, (gentle bump on back of slide put her Into battery).

Obviously as soon as I started having issues, I switched out supplied mags to mags on hand that are known to work. Issues continued. That night I cleaned her and lubed it lightly without seeing anything obvious.

Next day I went back out with my 17 and shot a full box through it making sure of the basics. Switched to the "L" and shot 30 rounds w/out issue. Then started having same problems as noted above.

As a control, I had my buddy come over who machines parts for his weaponry and other toys (pretty high speed guy) and he jumped in with both feet sure that I was source of problem. Same issues as I described happened to to him too.

However when he switched his grip up into the "tea cup/saucer" hold, problems ceased. Same for me.

Nothing more really than a rant/advisory, (glocks do sometimes fail). However I am curious if anyone else has experienced these issues? Looking on the web, it does appear as though others have had the same issues with the long slide 17. Curious as to why the long slide would induce these issues vs the standard.

As of now the gun is on the way back to Glock. Shall see what happens?

I've got several Glocks and have never had any issues with any of them... well except for one spectacular jam that required a rawhide mallet to un-jam it. That was caused by a reload that had a bulge in the case (range ammo, not mine). Anyway, what ammo are you using? I've been reading on one of the reload forums that some of the foreign mfg stuff had been having some cycling issues, 9mm ZQ being one of them.

The fact that changing your grip cured the problem leads me to believe the ammo is too lightly loaded. Grasping at straws... a quick check on the velocity would help verify this. Hopefully you can access to a chronograph.

Didn't see if these were factor fodder? or your home brew?

Wife's Para 9 had a problem with feed. I send guns to cylinder and slide before I ever shoot them. Hers I did not!! Cant remember the brand of Factory Fodder that hers had a problem digesting but after a trip to the shop, where they worked on the feed ramp as part of their services, it shooooooots anything!! without fail

Well obviously your problem is you bout a 9mm. Other than that, try buying some premium ammo. Cheap factory stuff is cheap for a good reason. If they are hand loads, reduce COL. Glocks and Sigs have a slightly smaller chamber. I think its because they measure in metrics (savages). Don't fully expand the brass. The cases will cork themselves in the chamber. You can polish down the expander die until it passes through by hand and just hits the second stage. Option B. switch out the expander die to a smaller caliber that will miss the first stage anyway, or a larger expander and only use the first stage.

Greg, I too have a couple other glocks. Combined, they have multiple thousands of round through them without a single failure. The failures on this gun, and the sheer number, were pretty interesting based on that fact alone.

The ammo that I used was winchester white box, remington, federal and some home brew that was pretty tame. It behaved as shown no matter the ammo.

In terms of the grip, as long as pressure was applied upwards on the magazine, there were no issues. Based on this my thoughts are concerned with the engagement within the well. What I don't understand though, is why this is seemingly an issue only for the 17L? I am not expecting too much from Glock based on stuff I have found on the web. If it comes back running the same, I will experiment with the recoil spring to see if I can speed the slide up. Like you, I am grasping at straws if this becomes my course of action.

I may have to explore this option as there was material transfer evident on the ramp. It was off to one side of the ramp and low. On my other Glocks that material transfer/groove is a line in the center of the ramp, running from mid ramp up to just before the chamber.

The COL was definitely within limits on my loads. Bullets used were Sierra tournament masters and remington jhp's.

All the loads whether my own or commercial, were on either 115's or 124's. I have seen some speculation out there that the long slide may work better with 147's. Once again, will see what happens after it comes back from Glock.

Wasn't sure if they worked on Plastic guns but looks as if they do. I have used this place for a good many guns both, Slide and Cylinder and have NOTHING BUT GOOD to say about them.

Thanks Big! I bookmarked them and may use them as they appear to have some well thought out services.

You might call them and have a talk to the smith. I use to send mine in with my request of " I Want it all " they will do what ever you want. After sending in as many as I had they told me what actually needed to be done and what didn't. They should know!! they do way more work on things than me. I like a company that sells satisfaction rather than a company that will gouge your wallet.

Looks to me that the feed angle is really steep.

I'm wondering if when you apply pressure on the magazine the mag is moving up just enough to lessen that angle?????

Exactly Jeff. The pics are not deceiving in this instance. Very un-glock like.

Picked the gun up from the shop last week. Pretty impressed with Glock's turn around as it was about two weeks from the time I dropped the gun off to the time I picked it up.

I have put 45 rounds through it without fail. What I did notice was that the transfer mark on the ramp is different. Whereas before the transfer mark was at 7 o'clock low, the transfer mark is now at 12 o'clock and nearly at the lip. I think they ended up replacing the barrel and restamping it with my serial number. The barrel is the only thing that looks "as new". The slide has a little holster mark that it was sent back with.

Curious thing that I did notice was that the gun was BONE DRY when it came back to me. My lube, (tetra) was not present and the smell was completely absent. I would have thought they would have at least put some of the copper lube on it. Easy remedy there though.

Should be good for a million rounds now...

Its good to know that they stand behind their product, and in a timely manner!!
