Glock 20 Jamming FTF

[Bolt_Action]

I have had 2 Glock 20 pistols now (Gen 3 Glock 20 SF), both with the same issue. Both of them will have an FTF jam every few dozen rounds. This is with multiple different brands of ammo, FMH and JHP. I've also tried a few different mags (all OEM Glock). The jams typically look like what you see in the photo I've attached. It looks almost as if the round isn't being fed straight into the chamber. The gun is stock other than the sights and a Wolff steel guide rod. I've tried different weight recoil springs (from 18 lbs to 22 lbs) but it doesn't affect the problem.

Any suggestions? I'm not interested in sending it back to Glock since this is the second Glock 20 I've had with this issue, and from what I hear they don't really bother helping customers with jamming guns.

If you've had two guns do the same thing, I would guess the problem is you.

Let someone else shoot it to help prove or disprove that.

Pretty strange and I was initially going to guess limp wrist, but no idea what a shooter could do to cause rounds to chamber crooked?

Are you using the same magazine?

Very interesting, sounds like there was a manufacturing defect. Maybe both of you can share the first letters or digits of your serials to see if they came from the same run?

Yes, I concur. Far from perfection.

But note that the Glock forum post that I linked with the guy with what sounds like the same problem is back from 2013.

I called Glock because I have the same problem I was told the problem was me and not the mags or followers, even though others here on CG and a Glock forum claim it's the followers for yrs.

Ugh. What a disaster. From what I'm reading on the Glock forum and what you've posted here, there's definitely several bad Glock 20 pistols, and it doesn't look like there's a straight forward fix. So much for the legendary Glock reliability. Oh well at least it was a cheap gun.

I have a Glock 17 Gen 3 that had one of several types of failures every 10 rounds or so. Out of warranty, I sent it to Glock. The connector, ejector, firing pin and trigger assembly were replaced, at no charge. The gun was returned in less that one week and has run flawlessly since. I wouldn't say that Glock doesn't care.

I own a Glock 20 and 29. I had similar issues with abunch probably 10 or more Glock mags .

Take the mags apart look inside the mag there is a plastic tang left over from manufacturing .
This tang causes the follower and spring to hang up use a small file and file the tang down. It's very frustrating issue to figure out. Because the issue could happen a number of times in one Mag or not at all. Dosnt mater ammo or if you limp wrist as others have said a 21 lb spring for the 20 and 22lb spring for the 29 seems like the perfect set up to run Wolf 40S&W all the way to the hottest you can load.
Hope this helps My Glock 20 and 29 are my favorites.

I have a gen 3 g20 and has pretty much been flawless using a 22poind spring. Only issue I have had was with one of the 10 round mags it would lock the slide back with one round left sometimes. But when I moved to az I tossed the 10 round mags into the Colorado river in Blythe and zero issues with the 15 rounders.
