Glock 17 Gen 4, sorted out or still problematic?

I picked another one up recently, with a manufacture date of 01/2014. It is good to go. No issues at all, including running it in a couple of matches.

I don’t have a Glock yet, but if memory serves, that a roll pin, correct? Interesting it would walk out like that, but in a sample size of 220 one would expect to see a quality issue or 2.

3 factory Glock night sights were loose. I peened two of them. Running cheap UMC 115 grain, no issues with feed, firing, extracting or ejecting. Will see just over a total of 2200 Gen4 G17’s by the end of the year.

Never been a huge fan of the factory night sights on Glocks I have shot. I’ll probably hand fit a set of Ameriglo Hacks or Warrens. Still interesting this issue popped up.

My sample size of 2 G4 17’s and a G4 19 have given me no real issues. My black G4 17 has around 14k on it now and I’ve only had primer detonation issues on crappy reloads. My FDE 17 has only about 600 on it and the 19 only has about 1k on it and with those low round counts hasn’t showed any issues.

I have a 17 Gen4 that I picked up a little over 2 years ago. It had at least ~30k rounds through it before I changed out the recoil spring, guide rod, and the trigger for competition.
I will say I don’t keep track of my malfunctions but I honestly don’t remember the last malf.

Solid steel. No roll pins in Glocks.

The Glocks I mention are W serial numbers as of right now. We do not have all 2200 pistols yet. We are getting them in batches. We are putting 80 pistols per week in service. Which means I am running 2, two day pistol courses per week at 10+ hours per day. I have little time for anything else. I am going to be pretty grouchy by the time this is over.

OK, thanks for the correction.

I have a Gen 4 17 made in April 2013, The serial number starts with U and it’s made in Austria. It came with the 30274 ejector. Just about 1500 rnds through it and no issues. The brass throws over my right shoulder around 4 to 5 o’clock consistently.

I have to move a couple more items to put together the funds for this, but I am hoping to pick one up this month if it all works out. I am still very curious to hear more first hand accounts good and bad.

I picked up an October 2013 made gen 4 17 last week. Ran it on Sunday and it was flawless. (Only 250 rounds though) Ejected between 3-4 o’clock. The trigger break seems to be a little more pronounced causing my poi to be left a little more than poa, but I’m working that out… Fwiw I had already installed a 3.5 bar and 6lb trigger spring. I’m sure that helped some, but it’s not quite where I want it yet. I’ve been dry firing it fairly often to try to settle it down. That’s my only complaint. My gen 3 26 shoots smoother, but it’s been around much longer.

Just picked up a Gen 4 G34. May 2013 test fire date. It’s a game gun, so I put in a ghost rocket w/ 4# striker spring, and polished as appropriate. 30274 ejector, VDL prefix. Only 400 rounds through it between mag tech 115 gr ball and 124gr Montana Gold reloads. Zero malfunctions so far, ejects somewhat less than brisk between 3:00 and 5:00, which just misses my right shoulder with the ball, reloads are hotter and ejection is stronger, of course. Ejects just fine with no mag inserted. We’ll see what happens as the round count goes up.

From what Mr. Vickers is saying, it is best to try to get a more recently produced sample. Can anyone point me toward serial number data breakdown for Glocks? Or at least how to ascertain the date code. Google is pointing me towards a few, but they are all dated. I found something on Glocktalk but considering the source I am skeptical at best.

If you’re buying new, there’s a test fire date stamped on the envelope with the spent casing. I’ve also seen the thread on Glocktalk but idk how accurate that is.

I bought my FDE Gen 4 17 right when the FDE models were released and have had ZERO issues with it. I’ve got about 1,500 rounds down the tube and still couldn’t be happier with it.

I purchased a gen 4 17 in January that was made in October. My log shows that I’ve shot 435 rounds through it without any issues. It’s also completely bone stock.

I know we are primarily talking about Gen 4 but my Gen 3 FDE 19 has a test date of 11/2013 with a W serial number. Right out of the box I was getting every fourth or fifth round to my forehead with Winchester white box 115. I swapped in a 30274 ejector and that fixed the problem so far through 400 more rounds of the Winchester.
My Gen 3 26 with W serial number from 1/2014 was perfect out of the box.

I don’t have the G17 but did pick up a G23 Gen 4 last month and have shot about 600rds so far and it has been flawless. Not sure on the 17 but if it’s anything like my 23 I say go for it.as

I have just under 1,000 rounds through my Gen 4 17, and I have never had a hiccup or a BTF issue. That is including with cheap, and steel cased ammunition. It’s been 100% good to go. My G19 gen 4 did have a few BTF ejections happen, but I have since installed the updated extractor and have not had any issues. My previous Gen 4 23 though, I blew out both pins above the trigger while firing. It was a cheap fix, but it was the last straw in shooting the .40 out of any Glock platform for me.

I just picked up a Gen 4 G17 with a test fire date of 10/13, serial number beginning with a W, that has the current RSA and ejector. I’ve only put about 100 rounds through it (really quick range trip to qual) but it performed well using a mix of 115 +p Winchester Ranger and 124 +p Federal HST. Brass ejected strongly to about the 4 o’clock position. I through my name on a waiting list for a blue lable Gen 4 G19, but who knows when they’ll have those in stock again…

9mm velocity at or below 930 FPS is responsible for most erratic ejection issues plaguing glock.

Edit: only stating what I’ve seen from 2 examples. Of course I’m sure not all BTF Glocks will act in this manner.
