How could anyone thumbs down a video from a friendly man showing every single step of how to disassemble your GLOCK? Great video. Anyone can watch this and understand.

This is one of those videos I keep in my library, under Glock’s, and return to for a refresher course on my G19. Thanks, Lenny.

Both the slide and frame dis and re-assembly are the best video tutorials I’ve ever seen. Especially knowing now how the Gen 5 differs from previous generations. So informative!!! Thank you very much. Outstanding.

Had an intermittent problem with my trigger not returning to battery. I was on the verge of sending my G17 back to Glock. This video saved me the hassle and embarrassment. The problem was that I did not insert the cruciform trigger bar under the curved lip of the silver leaf spring in the trigger housing, but left it on top after cleaning and assembly. I bought Lenny Magill's previous Glock disassembly video a few years back and referred to it during my troubleshooting, but it had the old cruciform arrangement with the spring hooking into it as did many of the other Glock videos that I researched online. So I still had no clue what the problem was until I watched this video. This is the best instruction -- especially if you follow along. Thanks Lenny.

I took the Glock Armorer's course about 20+ years ago, but now we may be getting Gen 5's, I'll do it again. thanks for the handy videos

new to guns and just used this video to learn how to disassemble and reassemble, much appreciated.

I don't know why it was so difficult to find someone disassembling the spring in the trigger housing, but Lenny helped make it *so* easy Sincerely appreciated 👍

Thank you for taking the time to literally strip the whole gun and show how to properly take it down. I have always been nervous to take apart my lower but after seeing this I now know what to do and that it's relatively simple. Your videos are great and I appreciate how thorough you are and how well you film. Best take down video on youtube.

Thanks so much. I was working on the trigger of my wife's glock17 and couldn't get the trigger right. You saved me from pulling out what little hair I have left!

ol Lenny Magill taking apart a Gen 5 Glock (or any video explaining something) is like ASMR lol. 5mins of needed content, 25mins of him slow dancing you through it. lol

Great job Lenny, really professional, friendly, knowledgeable, experienced and comfortable with the subject. You know your Glocks! I'll refer to this often I'm sure.

I am always impressed by the elegant simplicity of Glock. Thank you for your videos, many people take apart Glocks on KZfaq. But none with the thoroughness, camera quality, and lighting you bring to bear

Just got started into customizing Glocks and MAN was this a life saver. Thanks, Mr. Magill!

Nice review. Just when I think there is too much detail, I learn something. His explanations are concise, technical yet easy to understand.

THANK YOU for these Glock-smithing videos. They have helped me out numerous times. I just installed the extended controls on my new G45. This video made it quick and painless.

Finally what i always wanted. Glock finally changed all the torsion spring and tension spring to compression springs. More reliable. Love the less pronounced hump and no finger grooves. Also the early firing pin retraction is an improvement.

Lenny! Glad to hear y’all made it to higher ground!! Thanks for the help; made some mods to an old Gen 3 over the years (thanks to your instruction) and just got my Gen 5 G19 slide lock lever the way I want it thanks to this video! Keep it up!

Watching this video in 2024 and still helpful, this help me to understand better my Glock G45, you won a follower

wiggling the slide release is the BEST tip. Comes out easy with just a little wiggle while you press on the pin. Just like Lenny said! Thank you Sir! 😀

Very excellent teaching and modeling the assembly and disassembly of the Glock. I NEEDED this video; took mine apart to polish the trigger steel and put it together WITHOUT PUTTING THE CRUCIBLE IN THE SPRING. Didn't work well, was concerned I had messed up my brand new Gen 5 Glock 19. I don't roll with $640 I can toss, so I was concerned. This answered my question and solved my serious dilemma. Thanks Lenny!

The trick to reinserting the slide stop lever is to compress the coil spring by inserting a small diameter punch through the slide stop lever hole in one side of the frame while pushing the slide stop in through the hole on the opposite side of the frame. This is much easier than trying to compress the coil spring from the top of the frame.

Mr Lenny is my favorite youtube gun channel. High quality content and the comments not full of gun nuts.

Love this guy's videos. Super in depth. Also, he has a way of helping you retain the information.

This is my roll of painters tape....there are MANY like it but this one is MINE- L.o.L.... Good stuff. Thank you Sir for your willingness to educate. I'm sure enjoying the gen 5's I have at the moment. The 34 is an especially accurate weapon. It's still new, but my 19 has 6000 rds' thus far and has earned a lot of trust from me. Thank's again for always being on the screen when I need conformation or help.

Thank you for the very easy step-by-step instructions on how to disassemble the lower, appreciate it

this is the most helpful gun disassembly video I've ever seen. Thanks so much!

Thank you Lenny, I appreciate your recommendation and not mess with the spring in the trigger housing. As you pointed out; plastic does wear down if you mess with it.

I was so glad to find this video, I really needed to clean my 19X. Thank you!

Videos awesome man!! Just taught me step by step how to completely disassemble my Glock 19 Gen 5! Amazing gun and company!! Thanks for the video buddy this some next Gen stuff 🤘🏻🤘🏻

Thanks! I just used this video as a guide and installed my own Black Yikes! Was going to take it to an armorer to have it done but after watching I figured I could give it a shot. The front pin on a Gen 5 is not as easy to re-install or at least I had a few minutes toil getting things lined up and the pin in, but it did go in and the pistol ops checks OK.

Just bought this Glock and after watching this all the tumblers have fallen in to place. Thanks, great video and very well done.

From the Philippines here we love your channel very comprehensive and detailed 👍👍⭐️⭐️⭐️⭐️⭐️

Lenny you explain everything Way Better on all your videos......Great Job as usual.

Great video, it was very helpful. I took apart my 34 gen 5 lower then popped in a new trigger and connector. Now off to the range to see how she runs. I had to subscribe. Thanks Lenny

Thanks Sir for your video . Very informative and easy to understand. Been a firearms instructor for 30 years. Glock is a great gun. Thanks again Jerry LLanes...

I'm glad I saw this! I just picked up a Gen 5 G34 and thought I'd messed something up when I popped the trigger out to polish it. Thanks for the education!

ONE MORE TIME, MR MAGILL SAVED THE DAY!!! GOD BLESS YOU MR. MAGILL.

Lenny videos are the best learned a lot from this man.

This video just saved my bacon. You guys deserve that follow.

great video, I am now proficient at all levels of maintaining my Glocks, Thanks Lenny.

Lenny is hilarious! He called the magazine release spring a "roll pin" a few times. He uses the words "capture" and " pressure" when other words are more appropriate for whatever he's describing at times, and ends up over-using those 2 words. He tries so hard though. I do still learn from these videos.

My theory about the one pin thing is that Glock is in the process of simplifying the internals in an effort to make a single multicaliber drop-in fire control group for a major redesign in a Gen6. It would be similar to Steyr or the Sig 320 system, that way customers could buy the serialized internal, and then buy different sized 9/20/357 frames and uppers. A different trigger module would be made for the larger caliber 45 ACP, 45 Glock, and the 10mm offerings. So, potentially, you could just buy two different drop in trigger groups and have access to every single Glock model out there.

Super helpful Lenny thank you so much! I am building my dream carry Gen 5 G19 and videos like this truly help for customizing my glock. Just wish the glockstore reps would email me back so I could get it customized directly from you guys/glockstore :)

Great video! I found that with the trigger pin insert, once you get the trigger, slide stop, and block put back in, sliding a 3/32 punch in the hole will line everything up nicely. Then carefully remove and slide the pin in. Will snap down into place easily.

Great job Lenny. I really appreciate your concise and kind instructions.

Great instructional video on takedown and reassembly, with a lot of bonus information. Thanks for posting.

now i have to sell my gen3 and buy gen5. i just love that new grip. Great video btw!

Thanks. This really helped me learn more about my new Gen5.

Was fearful taking my first handgun apart to the frame. This video changed that feeling entirely once I had it apart cleaned and back together in minutes.

So glad you finally learned the right way to remove the slide stop pin! There was a time when you said to pound it out with a hammer!

You know your stuff. Helpful and detailed. Can't say anything I didn't understand and that is something very rare LOL.

Great video, thank you! And now I know that I need to get a Gen 5-specific extended slide lock.

Well, I don't thumbs UP many videos, but you got me on this one. Excellent. I own this exact gun so enjoyed seeing it took apart.

Thanks Lenny. I appreciate the videos. I’m in the Deep South so I hope to visit your store’s new Nashville, Tennessee location soon.

useful and precious video, peace and love from Italy

I've used this video many times as I strip the receiver to replace parts. If anything it's comforting to know I'm going step by step.

Lenny's video's kick ass. Thanks..

Thanks for the vid! Very informational, was doing a field strip and maintenance after the range with my brand new Glock 19 gen 5 and during reassembly I notice my ejector is lightly rubbing against a groove on the back plate and I was wondering is this normal??? not sure if it’s because of the bent shape or if it’s defective but I wanted to get some feedback before I contact Glock about it, again it’s nothing crazy just a slight concern that my ejector is slightly grazing against my back plate during assembly Thanks in advance

Such a great video Lenny. Thank you!

This video was super helpful in installing a new takedown lever.

Great video. I'm very good disassembling gen 3's and 4's. Just got the new g45 gen5. And was wondering about the crucible of the trigger bar. And the slide lock, how in the hell, do you get that out? Well thanks to you, now I know, Very informative video, thanks for the info!

Thank you ,great video 🦾👀🇺🇸🇺🇸🇺🇸

Brother, you make one damn fine video. Safe and completely thorough.

Informative as always.

Very nice, you do a great job of explaining why,, this and that very helpful.

awesome! thankyou so much for the 2 videos!!

Interesting instructional video enjoyed that Lenny 👍

What do you recommend using to clean the parts of the lower? I know many just use alcohol to clean the slide assembly parts, same for lower?

Thanks man I got drunk the other night and threw up all over myself including my Glock I needed this video to clean it up

Mr Lenny, shouldn't there be a tension ratio between the fire pin assembly coil and the trigger assembly coil, since each pressures the other at a different moment? If so, shouldn't these two coils be sold as a pair, depending on their tension ratio?

You saved me a lot of frustration with trigger pin 📌

Great tutorial. Thank you!

Slide lock spring. Should be called Fly Lock Spring. Mine flew like a bat outa hell during assembly. Lucky I found it on the windowsill. You’ve got some darn good take um and put um back together again for Glocks.

Thanks for the great video👍🏼👍🏼

Great video, extremely helpful thanks.

Aweome videos helped me out a lot thanks lenny

Will use this video when I start to modify my Glock 17 Gen 5 .

Very informative! Thank u kind sir!

THANKS LENNY 😊

So my question is does it have any benefit to change the locking block to the titanium version?

THANK YOU LENNY!

So does Lasermax make a Guide Rod Laser for this that comes with a replacement spring and take down lever that work together? (that looks like it can't move left to right because of that spring....and would be a BIG PAIN to install)

Very helpful as always! Thanks

Why would anyone stay in California if you own a gun store? Very informative. Thanks for the info. I did my 19 right along with you.

Excellent video thank you 👍

Does the Magazine release on the Gen 4 work for the Gen 5 Lenny ?

Ok, so if anYone can answer , I would appreciate it. So I just got a glock 20 and I watched the video on oiling the glock 20. If I'm suppose to clean it before first use, what do I actually clean and how? Already everyone (including manual) says to not clean the copper off the rails on slide... but everyone (even the manual) explains it as If the gun is dirty. On barrel and bore: Should I just wipe everything down with a rag and re oil? Or should I clean with solvent then re oil? (The manual speaks of using oil, never mentions solvent) On the slide itself , should I just wipe factory set oil off as much as I can and re oil parts that need it? I'm already not even wanting to wipe the slide rails at all because of that copper, but I don't think a rag would dig that deep, do I add oil where that copper is at all?... part of me just want to think that all I should really do is clean that barrel, and the rest after It has been fired for a while. I will go find the cleaning video,.maybe its explained there. P.s. this is my first glock, so please forgive my ignorance .🇺🇸

Good info. Thanks for posting.

Awesome video..thanks!!

Very informative, always great to know the mechanics of your gun! Also helpful when you need to replace parts. Thanks for the video sir 👍

You sir are a lifesaver! Thank you so much

Great video! Thank you Thank you!

just got my G17 G5 blue label standard plastic sights front slide serrations. Glock made some good changes don't like the plastic captive trigger return. Been a Glock armorer for decades. Got to take a new class. many gen 3s with parts. will have to get a separate tool box for this one. Not convinced about the barrel. Think it is more ballistic ID. I know a lot of really good shooters who cannot out shoot the stock barrel 9mm Major really have to het customer barrels.

Do I need to take the pin out that holds the backstrap still to get the trigger out?

Hi, I just disassembled and reassembled however whenever I went to function check it, the trigger would reset whenever I would pull the slide back just a hair instead of where it would normally reset any help is appreciated

ya know, cleaning my glock after doing a full clean on my beretta 85bb, really makes me appreciate how easy glocks just are LMAO

Very helpful! Thank You very much! :)

Lenny is my idol!

QUESTION...must you take lower fully appart to replace lock lever hate the factory one i habe on my glock 21

It’s like that on the locking block so it can still be interchangeable between other glocks
