Comparing Gen 3 and Gen 4 Glocks

[@dgillespie13]

If a Glock could talk it would sound exactly like Lenny. Thanks: always simple, clear and to the point.

[@hotroddin0440]

Yes, Gen 3 subcompacts (26, 27, 33) already have dual spring guide rods.

[@godzilladeathmatch]

I just bought my first hand gun...a gen 3 glock 19....fuckin' awesome gun...I will be buying more glock's in the future...

[@rickyjohnson9594]

U got the better one those dumb back straps on gen 4 gets loose as the dule spring s had problems to I heard gen 3 all day

Hopefully Glock will keep on making the Gen 3. I have friends in CA who love Glocks and I myself prefer the Gen 3.

[@Rob_Nasty]

Gen three. A better Glock true

[@echothreeonesix4425]

I have just learned to overcome my left handedness... i just use the middle finger of my firing hand to operate the mag release. it's worked so far...

[@ElCineHefe]

I'm a lefty and I've always used my trigger finger to drop the mag. It was never a problem.

[@donflamingo1084]

I'm not a fan of the gen 4 models, I've always liked the gen 3 models

[@Joe.91s]

What makes gen 3s better? just curious because im deciding between a 3 and a 4 @Captain -

[@Loueloui]

A very professional and informative video. I am a military veteran, and a casual gun enthusiast. I have a few guns, and I enjoy target shooting occasionally to keep my skills sharp. One thing I've noticed that a LOT of gun shops alienate their customers by having a condescending attitude that is both unprofessional and unhelpful. It is that type of attitude that keeps more folks from enjoying gun ownership. Thank you for being an exception to the rule! Now I know where to buy my next gun.

[@Shmash_whatever]

Thanks for the video, customers ask me all the time the difference between the gen 3 and gen 4 and its nice to be able to have something i can reference them to if they don't want to take my word for it

[@RandoPandaSmiles]

Many of the subcompact (G26, G27's, etc) Glocks had double recoil springs way before Gen 4's came out. Based on the hump you describe, I'd say it's a Gen 3.

[@Gizmoimages]

I bought a Glock 29 about twelve years ago and was very impressed the way the spring functioned in working the slide. Especially when handloading hot 200 grain projectiles. It handled the loads better than my Glock 20. I'm surprised they decided to change the spring since the old one worked so well. The upgrades they made from the original Glock 20 were needed.

[@1st_Amendment_Is_My_Right]

I carry a Glock 22 Gen 3 on duty and i've shot the Gen 4 before . I like the Gen 3 better because of the grip itself. The grip on the Gen 4 is way to rough and unconferrable for me as a person. But a lot of the other officers like the Gen 4 over the Gen 3. But each person is their own.

[@rickyjohnson9594]

Gen 4 get loose at pin that holds on the back straps who need those bk straps all get loose at top

[@Nikonik66]

Watching this video in April 2022. Lenny doesn't look so young any more but still looking great, and still making great videos.

[@samchowdhury3755]

I have small hands and I use it without the extension grips. It interchangeable, so the grips will not be an issue. It made for everyone. Only thing I don't like about the gun is the the handle is to wide because of the double stack magazine and it is very hard to conceal with fitted clothing. Other than that, the gun is flawless.

[@TRIP66638]

the trigger is harder on the gen 4 cause of bump it has that when file down is a lot better

[@mikecrabtree8200]

The gen4 also has a beaver tail back strap which is why I bought one

[@si_vis_pacempara_bellum4906]

I wouldn't call Gen 4's mag release "ambi", it's reversible. Ambi mag release is something like HK's paddle release, or a thumb release that you can push from either side without changing it.

[@alangohary]

Covered all my questions in this great video. Thank you!

[@matthewquigley767]

Great and informative video. I am buying my first G19 next week and this gives me even more confidence in the purchase. I am purchasing the Gen 4, but have only shot a Gen 3. Thank you once again for such an informative video.

[@kevinfair4174]

I must have a freak gen 3 Glock 27. I bought it new and never altered it. It has the large guide spring hole.

[@d-boyzeighteenhundred]

@Kevin Fair - I believe many of the subcompacts automatically come with the large spring even way before GEN 4

[@getbo]

"It says Gen 4 on the side" "that is your first clue it is a gen 4 gun" ......that's not a clue.....it's the answer!

[@r3drummurd3r68]

Get the real f****** comedian here huh?!

[@ss396rat]

This guy has the best informative videos

[@getcoolb]

all subcompact glocks have had the dual nested spring assembly for a long time. All they did is transfer that to all Gen4 models (full size and compact)

[@Docprepper]

I have a Glock 27 gen 3 and it has a dual recoil spring with the larger guide rod hole

[@Hawk60ce]

The 'baby' sized blocks always had dual recoil springs. Gen 4 incorporated them into all the guns

[@Docprepper]

That's what I figured. I had to prove it to a few ffls lol

[@ashleycoyle4137]

Thanks, this video cleared up, and corrected a ton of 'Gun Store Guru's' who had no idea what they were talking about. Mags being compatible with all both Gen's is usually what most 'Gun Store Guru's' get wrong.

[@freemason671]

This guy is awesome, their whole Co. is just great, love how he stays making all the vids we want to see on Glocks!!

[@unksoldr]

Just bought what I was told was a NIB G27Gen4. However, it doesn't say Gen4 on the slide though it has the dual recoil spring. The frame has the Gen3 mag release. So WTF?

[@grantlandneil]

I do not see an advantage of the gen 4 over the gen 3's or previous Glocks. Why change something when it works?

[@tubeyou22973]

My g30 wich is Gen 3 has same spring as as 4th Gen

[@hotroddin0440]

You have a gen3, the 26, 27, & 33 already had the dual spring as a gen3.

[@brego129]

Just wanted to say thank you for your videos Lenny. Very professional and informative and I will probably be buying some parts from Glock Store soon. Thanks again for the videos!

[@xXShadowWolf1Xx1]

I bought a brand-new Glock 30 GEN three but it had a double recoil spring not a single spring

[@PracticallySquared1]

Great video. When I bought my last Glock 26 I was debating between a GEN three or gen four and one thing that you didn't mention was that the gen fours come with three magazines opposed to the Gen threes only coming with two. The gen four was only about $25 more and for the money you get the extra mag and all that stuff you mentioned and it's hard to find a 10 round Glock mags for under $25 so that's what made me buy the gen 4. The extra mag plus all the features you mentioned. Not sure if all the gen fours come with the extra mags but if they do and the price is close I'd buy the gen 4 every time.

[@Theziptieman]

Just cause the mags wtf 😂 weirdo

[@raftika1]

1:00 im sorry im new but what are those for? what is the purpose of a guide rode hole?

[@jesuscruz8705]

going to outfit a Glock 21 with 460 Rowland; makes it hit like a .44 Magnum. The bigger round mean stronger magazine needed (best way to put it). was curious about the gen 4 vs gen 3 mag difference.

[@jeffmacdougall9190]

won't that wear the shit out of the slide? i suppose depends on how much you shoot as well

[@rickyjohnson9594]

Gen 3 gold standard model

[@Mike_The_Hog_A_Nator]

This is old & times have changed 🤟 I bought a $200 Gen 3 PSA Dagger SW4 GatorMouth cut, RMR milled, threaded barrel, suppressor sights in FDE, Complete Slide for my Gen 5 G19X & it fits & performs perfectly.. I bought the G (SAP) Adapter to fill that small gap between the frame & slide in the front but just swap out the backplates if you have a complete Gen 3 slide for your Gen 4 or 5 frames 🤟

[@douglasphillips24]

Some gen3 Mags got cut too be a gen4 & new gen4 mags are all plastic with no metal exposed.

[@calholli]

So all of the upper parts on gen 4 are still compatible with the gen 3? extractor and spring assembly, firing pin safety, firing pin assembly and back plate?..... So can I still use a gen 3 UPK on a gen 4 slide? (other than the guide rod, obviously).

[@dddutuber1]

Lenny, Not having held a Gen 4 with a +4 grip panel, to what would you liken it?

[@DirtyK1911]

SO.... other than the guide rod assembly and guide rod hole, can you put a Gen 4 slide on a Gen 3 frame??? Can you use a Gen 4 slide on a Polymer 80 frame with the use of a Gen 3 guide rod and adapter??? Thanks!

[@joelokey5362]

What's the difference between the tungstun and stainless? Which is better? And which weight should I go with? 22lb? when shooting +p ammo?

[@arnonfly]

a question abut the LaserMax Sight: Glock GAN4 comes with a dual and upgraded spring on the Guide Rod. The laser has only one spring. Does that bring me back to "Glock GAN3"?

[@abnrgr7569]

I have a Glock 27. It has the gen 4 slide with the hole ,but the mag release is not ambidextrous its only on the left side. I'm trying to figure out it's generation.

[@davidc1074]

UPDATE for my erratic ejections and btf with my gen4 19 with updated spring and ejector: Glock called me and said they replaced the extractor, ejector, and trigger housing on my 19. They said they ran 500 erratic ejection/ btf free rounds (as I requested) without any issues. They said the problem is fixed and gun will ship tomorrow and should take 2 days to get to me. I sent it in on the 12th, today is the 17th. Pretty quick turnaround especially during Christmas time. If you want one go ahead and buy it, if you do experience problems, just call Glock and they will take care of you. When they tell you to ship your gun in, request that they send you a prepaid shipping label. Here is a good link that helped me write my requests for Glock to repair on a piece of paper sent to them with my gun. All your Glock Gen 4 pistol questions answered! If they don't fix it the first time then just keep sending it in until they do, or they will have to replace it. That's what I'm gonna do, say on your request paper that its the 2nd time or the 3rd time and you want to a replacement gun of your choice and your choice of date of manufacture. (more explained in link) A good functioning Glock 19 may be the best handgun/CC gun you will own. I came to this conclusion after buying a very expensive ($705 after tax) polished stainless steel CZ75b. I sold it the next day for a bit more than what I paid without firing it, and here is why. Yes it was gorgeous, all steel, and prolly was just as reliable and shot more accurately than my 19. Action was so smooth and everything about the gun was great, but it was very long, heavy, not an easy CC gun, and I already had what I needed in my 19. Did I mention it was very expensive? At least for me, I didn't need another handgun and had a lot more I could do with $700. Plus aftermarket parts would be harder to find and not as many to choose from, sights, holsters, etc. I wanted to give up on Glock after my experience but there just is no replacement for one that works the way it should. Xdm's are overpriced for what they are, M&Ps have problems of their own (jamming, barrel issues) Sigs are too expensive, so on and so on. Glock 19 just works best for me and I'm going to stick with them, and only train with this one gun unless I absolutely have to give it up , then I may sell it and get another Cz compact or something.... Go for it, most people have Gen 4's that work flawlessly. Hope my experience can help you, good luck

[@mrmatthewpaul]

how about the barrels? Are you able to take a gen 3 barrel and use it in a gen 4?

I ordered a trigger. It said it wouldn’t bill me till my order shipped. It took my money right away. Then I call 12 days after I placed my order because I didn’t get a response to my 3 emails. Then they tell my is on back order. At this point will never buy from here again. They didn’t even seem to care.

Does this go for the "new" g30sf ? I bought it in early Feb this year and it has features of both . the test fire date was 7/28/2011 does the date make it gen 4? there is no gen 4 mark on slide

[@jastark22181]

Is it possible to have a Gen 4 upper and Gen 3 lower on a Glock 27 but have the same serial #?? I just got it a few days ago, used from a gun shop and I'm new to Glocks. But from almost everything I seen in this video is pointing to that. I have the dual spring guide rod with the bigger end and the little hole in the end of the rod, but no replaceable grips, the same texture on the grip as a Gen 3 and it DOES NOT say Gen 4 on the slide. I'm not even finished with the video yet but I have a feeling their will be more differences.

[@fredbloggs6080]

He should have pointed out something I saw in another video--the Glock 26 and 27 Gen 3 already have the dual recoil springs.

This got me a little confused. I just purchased a new model 26 and it does not say Gen 4 however it has everything in this video that the Gen4 has except for the grip knurling and grip panels. The guide. hole, guide rod and the clips it came with are the same as the 4. I know he said that they are making all Glocks now with the Gen4 magazines. Is this video correct?

[@roadglide]

Want to clarify. The G19 Gen 3 is not ambidextrous. You cannot switch the mag release on these particular firearms. Because it is not, using both Gen 4 and Gen 3 magazines is acceptable. If it were ambidextrous and switched the mag release button for left hand you could not use the Gen 3 magazines only Gen 4.

very informative and well spoken, just wondering why the change?

Hello Lenny I’ve been wanting to buy a Glock for a while and I finally bought one but when I got mind it’s not like what I’ve been seeing on all the reviews so my question is ( if I buy a brand new Glock from a gun dealer what will it come with it?) as from Glock.

[@mechveteran01]

***** The gen3 mag release is not changeable for lefty use, if you want to be able to have the mag release on the opposite (either) side of the pistol you'll need to pick up a gen4.

[@lastdaysguitar]

I have to say that I like my Gen 4 G22 trigger much better than the trigger on my G19... not sure if they did anything different on the trigger, but I recently picked up a new Gen 3, and the Gen 3 G19 trigger noticeably pulls harder than the Gen 4 G19 - at least the one I have... does anyone know if they improved the trigger? Or did I just get a lemon trigger on the Gen3?

[@davidc1074]

I have a gen 4 Glock 19 made in 2013 with the updated spring and ejector, and still get consistent erratic ejections and BTF. Limp wristing isn't the issue, I have shot a gen 3 and only this one has given me these issues. The spent casing has a slight triangular scratch on the top which , from my research, indicates that it may be hitting something it shouldn't on its way out instead of having a clean ejection out to the side. I have about 650 rounds through it and still have this problem. Glock sent me a prepaid shipping label so I am going to have to send it to them, and from what I have read on with other people with this problem, it may take 2 or 3 times sending it back before the problem is fixed or the gun is replaced completely. Anyone with any suggestions would be appreciated. I know that most of the newer Gen 4s are good to go , I must have gotten a lemon. It goes bang every time, never had a FTF but I did have a stove pipe but I had released the mag before I shot the last bullet for some reason and that's the only time it happened. Also the slide failed to lock back after the last round twice, this only happened when I filled the mag with 10 rounds instead of 15 although it could have been my grip. Almost wanted to give up on Glock after hearing this issue is present in many newer Gen3's as well, but I love the midsize so I decided to see if they could fix it before I bought another brand. Sending my 19 in today or tomorrow, wish me luck.
