View Full Version : Glock 17 Gen 4, sorted out or still problematic?

I've really been strongly considering picking up a G17 Gen 4 for IDPA SSP, some CCW, and nightstand duty. I really like the Gen 4's grip and ability to add a beaver tail, as "glock bite" is the reason I moved to M&Ps years ago.
I know these pistols were plagued with problems when the Gen 4s first came on the scene. Have they gotten them sorted out with the latest ones? I'm looking to buy brand new one for right around $500.
Thoughts?
ETA: I should preface this by saying I'm a little gunshy (no pun) after the P30 LEM experience (https://www.m4carbine.net/showthread.php?65990-HK-P30-Break-In&p=939080#post939080) I had a few years ago.

Buy it. I'm right at 2K rounds with mine and have had zero BTF or any other malfunctions to speak of. I recently noticed grant posted that some Glocks are showing issues between the 2-4K round marker. I will update if I do start to see any problems, but from my standpoint, I don't see any reason to not get one if you're interested.

Well my wife won't be too happy about your response, but I am. ;) Thanks for the response!
I have the gen 3 17 and like it but i really like the grip on the 17 gen 4
Not the 17 but I have a VAP Gen. 4 19 that is running great right at around 1,000 rounds. I tossed the APEX extractor in from the beginning just for peace of mind. A friend has a US-made 7-digit gun (AA something, I think) with the factory extractor, and it seems to be running fine, albeit at only 300 rounds or so. I think the newer Glock tend to be good, and fairly easy to fix if they're not (I had an RTF2 19 that choked every chance it got, but Randy Lee worked his magic and made it run).

The current production Gen4 Glock 17's seem to have the problems fixed. Aside from a number of reviews of the late model Gen 4's, I picked up a blue label Glock 17 gen 4 about two months ago. I only have about 1200-1300 rounds through it at this point, but have not had ONE malfunction yet. (this will probably jinx me now...)
Reconsidered and reopened at OP request.
Several dozen gen4 G17, G19, G26s, serials S through W, 2012-2014 production, without malfunction.

This is exactly the sort of thing I was looking for when I started the thread, thank you for your input Skintop.
ETA: There are some rumblings of people encountering issues when the pistol gets to approximately 1k-3k rounds. Has anyone noticed this at all? I see that Glock recommends recoil spring replacement at 5k for the Gen 4s, perhaps this is why the issues start.

For those who know about a large enough sampling size, any idea how far back in production is considered current enough to have better odds of picking up a non-problematic Gen 4?

S through W does that mean the first letter on the serial number?

I ran an gen4 G19 RSA out to 7,839 rds before I changed it. I may stick that RSA back in the gun to generate more data since it's now a pool gun.

Good to know, thanks man.
We took delivery of 25 Gen4 G17s at the academy I have a second job at (fall of last year). at least 15 of them are at the 600 round mark and in early May 2014, these 15 will hit the 1200 round mark. I have one….they are prefixed VXFxxx. No issues or complaints to me but these are cadets and may not know what is right. The one I have does seem to behave. I did replace the Gen 4 trigger bar with a Gen 3 trigger bar and a Glock minus connector with a trigger average just over 6 lbs. We use whatever ball ammo we could find….usually Speer or Federal. I saw the ammo for the upcoming class….we will be using Speer 115 ball this go around.
I have 3 gen 4 Glocks. 17, 19 and 20.
The 19 probably have somewhere between 7-9000 rounds and the 17 between 3-5000.
The only malfunctions came from a bad production of Geco ammo (seemed to varying amount of powder in them).
With ammo which is in spec, they have been 100% reliable.
But have noticed ejection varies between 2 o'clock and approx 5.30.
I have no problems recommending them

That's really surprising to hear of issues with the Swiss Geco ammo. I guess everyone producing ammo is letting their quality slip these days. That's a real shame as I've always found European ammo (especially 9mm) to be pretty solid.
Thanks for the feedback, Skoal!
In the last 6 weeks I have personally seen 220 new serial G17 Gen 4's and another training team has seen about the same number. All current 042 RSA and 30274 ejectors. 1 locking block pin partially walked out. Not sure why, but it was reset and held since. 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.

Are these Austrian guns or US produced? (not that I've heard anything to indicate any difference whatsoever; just curious).

I just bought a Gen 3 G17 last week and put a couple hundred rounds through it so far and it ran flawlessly. Great ejection, nice trigger and very accurate. I know you asked about Gen4, but I hope this helps.
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.

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.
9mm velocity at or below 930 FPS is responsible for most erratic ejection issues plaguing glock.
I beg to differ. Ive shot Gold Dot LE loads and just had more forceful brass to the face in a bad gun. The only difference velocity made was how hard you got hit.
A few new gen4 G19s and G17s just in, X and W serials, born 03/2014, all Austrian. Typical of other configurations reported, 30274 ejector, (.) connector. Golly I love new guns, but these are way too clean and have no character marks. I think I'll fix that this weekend.

Have they (glock or Lipsey's) made a batch of Gen4 guns in OD...in addition to FDE?
http://www.glockmeister.com/GLOCK-Pistols/departments/2/
Or is this something that glockmeister is having cerakoted on their own?
We cleared the WR serial numbers and are in the WS range. Nothing to add since last post other than we used up all the 115gr UMC and are now running 124gr AE. All pistols running as expected. Getting hot like hell and summer is still not here.

They're factory OD. I have a Gen 4 G19 in that color.
Does anyone have experience with a recently made gen 3 glock 17 or 19? I would feel reasonably confident buying a gen 4 at this point, but I haven't heard much about gen 3s for a while now.

I've seen a few shoot, and they have been fine.
That being said, I can't find a compelling reason to choose a gen3 over a gen4 unless required to do so.
From the overall feedback that I've heard, Gen 4's seem to be a bit more accurate than Gen 3's.

I have an FDE Gen 3 G19 that is serial range WZ that I've fired 1100 rounds through. No malfs and ejection seems more consistent in arc than I'm accustomed to.
Bit of an old thread, but...
I have a Gen4 G26, OD, test fire date June 2013, bought new by me in July 2013.
So far I have a little over 1,100 rounds through it. 3 malfunctions.
1. Failure to feed using Winchester Ranger JHP. I've come to distrust Winchester the past years, so I was using it only at the range. The recoil/report felt weird, so it very well could have been ammo. Still didn't like it.
2. Failure to feed using a several-years-old Korean brand magazine (KCI), whose springs feel weak and whose follower hangs up sometimes. Easy to blame the mag here.
3. Failure to feed using a Glock brand magazine and factory brass 115gr FMJ ammo. This magazine was an original 10 rounder from my Gen3 G26 that I had had since 2005, don't know the round count, but it was used a good bit and spent most of that time loaded. I replaced the magazine spring but haven't used it enough since to say anything.
So there are very plausible reasons for each of those malfunctions that are not the gun's fault.
But still, with 3 malfs in 1,100 rounds...I haven't been carrying it. Another several hundred + rounds without issue and I'll consider carrying it again.

Personally I am more interested in the 17, but I am sure others will be very glad to read of your observations with the Gen 4 26. I'm having a hell of a time trying to make a decision between a Gen 4 G17 and a Beretta 92A1 at this point.

Only got 800 rounds through my UBB prefix gen 4 17, but only 1 BTF (early on) and no issues feeding/extracting/ejecting.
1 locking block pin partially walked out. Not sure why, but it was reset and held since.
Had one of these also on a Gen 4. Personally owned / agency approved gun which was detail stripped by an agency armorer for inspection and the pin was not centered properly during re-assembly. The pin will walk if not centered and stays in place once it is installed correctly.
i haven't had any issues with feeding or firing, but ejection has been slowly moving to 6 o'clock on my 3rd gen (2013 production). starting to really piss me off with all the brass in my face.

This is exactly what I am most worried about. At the risk of revoking my man card, I have a really hard time resisting the urge to snatch and anticipate the shot on pistols that habitually nail me in the face with brass. A pistol that does this is pretty much worthless to me.

Sample size of one but I have a newly purchased Gen4 Glock 19 that has not had problems with ejection (95% consistent to 3-4 oclock, ~5% impacting my right shoulder) through the first ~200 rounds. Serial prefix of WW, production date of March 2014.
I've seen around a dozen or so Austrian Gen 4 17s and 34s with 30274 ejectors (serials starting with an "S" through "W") pop Federal white box 115 brass directly to the rear and down ladies' blouses. They'll let you know quick.

My gen 3 19 with the 274 extractor seems to BTF 1/100 rounds. It's just shy of 1k.
On the other hand at a pistol class I was at a girl had a gen 4 17, that she couldn't do one handed shooting exercises because it would have "limp wrist" malfunctions. The fact that she couldn't make the pistol run one handed is pretty unacceptable to me. She's replacing her glock with an xdm.

That is a user problem and not a weapon problem. If the grip is too bulkly/long then select a smaller sized variant like your G19. Jumping to an XDM is not step up.

I tried my damdest to get my new Gen4 G19 to "limp wrist" at the range today.
I have five Glocks, and I can't for the life of me figure out how people get them to "limp wrist".
I'm right handed, I fired it as weak as I could possibly hold it (safely),recoiling all over the damn place, one handed, off handed, with one finger...or half a finger...even touching the grip. Loose wrist too.

Agreed. That's why no matter how hard I wanted to make my G30S work for me, it just didnt. Grip was too short and too wide at the backstrap. Plus I found the recoil a bit much to stay on target after more than a couple rounds. The G19 Gen4 and G17 Gen4 are another thing altogether. Point is moving to the same platform but in slighty different dimensions can work wonders. Going to an XDM over Glock? Too much going on with them with the backstrap safety and high bore axis, especially if one is already familiar with the most simple platform out there.

This is the sole reason that my 12 year old Glock 19, gen3 has been retired and replaced by a Glock 19, gen4 with the large beaver tail grip panel. My hands are just a bit too big for the gen3 gun, although I carried it off-duty for 12 years and made it work. The gen4's large grip with the beaver tail panel made a huge difference.
I gave up trying to get the newer gun to malfunction. Got bored as the gun just kept on keeping on...

Another data point for the mix. I was in a pistol class Saturday, and my beloved Gen3 G17 crapped the bed. The rear sight was hanging halfway off the frame after the first six rounds. This was my nightstand gun that has over 14,370+ rounds since I bought it used, as a police trade in. And I'd shot the thing just 4 days before with no issues.
Out comes the NIB Gen4 G17 I brought to run a magazine through, while the other students went out for lunch. Just under 400 rounds fired that day, most of it weak hand only. No issues at all - no brass to face, no failures to extract/eject, nothing. Ran like a top.
Oh, and the new Gen4 has a Grip Force Adapter, Vicker's slide release, and Ameriglo Hackathorn sights. Still debating the mag release. Trigger and connector are stock.
Already bring a spare gun to class, even after you have double-checked your primary handgun.
As we come toward the end of 2014 I was wondering what the current consensus on Gen 4 Glocks is? I haven't seen anything negative recently but was wondering what you all have observed.

Once I received the updated RSA, I am approaching 15K with my G17. With my reloads, once in awhile one will come straight back. It just keeps on shooting.
I'm happy to say that my three have been 100% reliable, with no problems at all. Two 19's and a 26. One 19 just passed 2500 rounds today. The Gen4 19 with the medium beavertail backstrap installed is the perfect carry gun for me.
Does anyone really know for sure, if current production Glock Gen 3 and Gen 4 9mm pistols have truly been fixed of the BTF issue ? If it has been fixed, approximately when was it fixed and what did Glock do to fix it ?
Member: Surf has vetted quite a few and keeps hard data on them. He posted about it over at P-F. Maybe he will jump in on his and share. In short, he's not seeing any issues with current production.

I have a 2013 made Gen 4 Glock 17 and a 2014 made Gen 4 Glock 19 and they have both been good. Having said that with all the Beretta talk going around I picked up a new M9 on sale for $435, took it to the range and shot it immediately better then the Glocks over our standard qual course. I haven't shot a DA/SA in years yet I was faster and more accurate with it and I haven't even gotten the D spring in the mail yet. I'm not sure what to do with this.....am I really going to go to the M9 for duty carry?

Thank you sir, that is exactly the type of information I am looking for.

I have one Glock, a G19 G3.
It has been trouble free. I don't want to tempt fate and ruin my perfect streak.
I will add to the post I made at P-F linked is that Glock is partially correct when they cite shooter platform and/or low powered ammo. We found in our 1800+ pistols recently fielded that erratic ejection was indeed linked to shooter platform and / or low powered ammo. This was only seen in a very low percentages overall. Any instance where this was found in a shooter the weapon was fired by multiple training personnel and the weapon ran fine. The shooters platform was worked on heavily for improvement and issues ceased. Of course in earlier production Gen 4's ammo and shooter platform was not necessarily the issue. All in all Gen4's produced in the 2014 time frame or later and I would have no reservations in picking one up. Of course like anything else, nothing is 100% but any further issues and I might relate that to normal production issues that can happen to any manufacturer.
I will also note that I have also seen 25 Gen4 G21's shooting 230gr Lawman FMJ and 230gr Speer GD and there have been zero issues. I have about another 25 or so to field this week.
It's a sample of one, but my Glock 17 Gen 4 that I bought brand new in November last year has 5.5k on it without a hiccup (except for a few FTF due to a bad lot of Geco ammo).
Glock 17 Gen4 purchased Feb this year (2014) currently sits at 2,950 rounds with no malfunctions, BTF, etc, good ejection .
I'm still up in the air about a gen 3 or 4 19, but only because of trigger feel. Even with a 3.5 lb connector a coworker's gen 4 still doesn't feel as nice as 2 of my factory gen 3's.

I had an early Gen 3 that has and continues to run great. I gave it as a gift to my new daughter in law because it had the best trigger in a large stable. She is diminutive but shoots it very well for a new shooter. But I can set my watch to when she tires in a shooting session and starts to get tonked with cases. I cannot get it to do that for me..

Put a gen 3 trigger bar into it.

Reading this thread I'm getting the impression the Gen 4's don't suffer so much from BTF's, but Gen 3 guns still often do.
Over the course of November-December I purchased a Gen 4 G17 and a Gen 3 G17. I haven't shot the Gen 4 yet, but the Gen 3 was very much "in your face" (pun intended) with the empty brass while shooting 115 gr Winchester white box. The Gen 3 also had a few failures to go completely in to battery in the first 50 rounds or so. I chalked it up to the gun being poorly lubricated since there was very little of that copper colored grease in the pistol. I lubed it and it was 100% for the following 150 rounds.
I'm a little concerned with the thinner "web" of the front of the slide on the Gen 4's where the RSA rests. There's a thread on TOS where someone has broken a Gen 4 Glock 17 at that point. The thicker web on the Gen 3 seems it would be more durable, but maybe not. Maybe that break is just a fluke since people aren't posting that as an issue on the net right and left.
Overall, how are the 2015 Gen 3's and Gen 4's doing? Okay, I'd expect?
I have about 18k through a Gen 4 34 and about 30k through a Gen 4 17 and they haven't broke.
Your Gen 3 shouldn't need to be lubed to run unless you're shooting a metric ton of ammo in one session.
Winchester white box it notoriously underpowered. I mainly run 115 grain reloads from LAX ammo or Wolf or the Bears and never have
I had a failure to go into battery in 4 years and about 15k rounds a year through mainly those 2 glocks noted above.
