Glock Gen5 - Upper Disassembly & Reassembly

Lenny Magill, Founder and CEO of Magill's GlockStore, does a deep dive into the new Glock G17 Gen5.
In this video, Lenny looks at the Upper and does a complete disassembly and reassembly.
The Glock 17, Gen5 is our Item #7927 and can be found here: www.glockstore....

[@blackedng8014]

Absolute lifesaver. I had a bonehead moment where I put the slide back on without the barrel or recoil spring (I don't know what I was thinking) and I quickly realized I was in a pickle. The slide wouldn't come off the lower. I googled Glock Gen 5 disassembly and this popped up, and now I know how to take apart the firing pin and safety. Thanks for the help and knowledge! Now I feel a lot more confident in my ability to fully take apart my Glock. And I did it all with a tiny flathead screwdriver.

Every time I watch one of Lenny's vids, I learn something about Glock's I didn't know. Thanks Len, I appreciate that.

[@tacticalmonkey770]

This is amazing info. He basically just gave everyone an armorer's course at no cost. My department just switched to G19 G5's so this is absolutely invaluable to me. Thank you, Lenny!

Lenny is a great teacher - talks to you not at you. He’s forgotten more than many Glock owners know.

I have to say, Lenny, these videos are immensely helpful. Thanks so much for making these and all that you do.

Things were crazy in CA when I got out of the Navy in San Pedro in 1968. Glad to see nothing has changed and next generations of crazies have taken over leadership of the state. The Gen 4 Glock 17 is one of my favorite sidearms used for LEOSA qualification and range fun.

[@cartap22]

I love San Pedro

[@ERINYES10]

Thank you Lenny! You just saved my life! I did a newbie move and removed the backplate without capturing. All the parts shot out and hit me in the eye. Took 30 mins to find them all and then had to figure how they went back in. Quite a learning experience.

Best videos on Glock cleaning/disassembly. It’s a lot to watch the entire thing, but when you want to do things right, it’s worth the time (for someone who isn’t an expert).

[@johng1902]

Definitely the BEST presenter of any I've seen on R/R for guns. Certainly for Glocks: Great lighting, great sound, great voice, slow and articulate speaking (TY x 2), calmly and smoothly shows each piece and part, great stories. Totally outstanding production. Had I seen Lenny before I bought my first gun, I'd've been a Glock fan for sure. Thank you!

[@fulcifan6946]

I don’t care how long the damn video is. Lenny’s voice is so soothing, he could come to my house every night to read me bedtime stories.

Yes, as some say, the videos are long but I like that the extra knowledge is shared. It shows Lenny's depth of knowledge of the Glock pistols. I advance the video to what I want to watch as I have used the videos multiple times.

I love these vids and I hope every Glock owner finds themselves right here. Hailing from Germany, thanks for the informative video!

[@heidelinkner8752]

Thank you so much, Lenny, for your great videos! I just got myself a Glock 19 Gen 5 and I'm watching your videos to learn more about it. You're a superb teacher, great voice and super easy to understand even for someone like me, who's from Austria, so English is not my native language. Please keep up this wonderful work, I'm looking forward to the next videos!

[@tcirilli]

Use tungsten disulfide (Ws2)! Dry powder, slipperiest thing on the planet, sheds carbon, bonds to metal by rubbing it on, doesn't attract dirt, doesn't come off, withstands 100,000 lbs. of force, eliminates wear. I run my guns dry with NO problems or signs of wear. Better than oil (oil attracts dirt) but if you are worried of what I say, Ws2 also blends well with oil and can be used together. I've been using it in my car's engine oil for 12 years and the engine is like brand new (no wear!!). Nasa uses Tungsten disulfide (Ws2) on the Mars rover. Great for guns! I use a short bristle 1/4 in. paint brush and a q tip to rub it on.

[@skate7destroy1]

I really appreciate you taking the time to run these tutorials, as I find them extremely helpful. One suggestion though. May I suggest making two videos? One like this one, an extended version where you spend a lot,ore time explaining all the aspects of each piece and part, how they come together, how the parts work, etc. And the other, an edited version for those of us who are actually disassembling and reassembling along with you. I spend a lot of time forward advancing these videos in 10 second incrimenrs, simply because when we're reassembling we're trying to complete the project. The backstory to each part, the new barrels crowning, the cost of each part, etc. All of these stories tend to make the assembling and reassembling process a little more confusing. Not that the back stories aren't interesting, the small changes from generation to generation, the overnight shipping costs on small inexpensive parts that get lost easily and are expensive to have shipped overnight. Just a thought. If you edited each process, the disassembly and reassembly, slowly but steadily, you could condense both processes down into 5 minutes for each, editing down a nearly one hour video into a very helpful and to the point, 10 minute video. Just a thought.

Lenny, I want to thank you for your video’s and your knowledge of the Glock.since I found one of your video’s I was sold on a Glock. I also like to watch video’s from other people and I am amazed on how they break down their Glocks. They don’t use the correct names of the parts. One guy had a really tough time removing the lower plate on the Mag! I wish I lived near by to take some or all of your classes.

Hey Lenny, side note about the alignment sleeve that lives inside the slide.. you can remove it by using a 9mm brass bore brush and it doesn't damage it at all. This was a happy mistake on my part, but useful knowledge for removing it. Cheers, thanks for the videos, they sure do help.

Great informative video, just purchased a new Glock 22 Gen 5, interesting you didn't clean your new guns, the reason I do is they always come over oiled and can be a little dirty from the test shot(s) so I do it for that and also to get familiar with the new gun, like this one, i cannot remove the slide the way you demoed, i follow the same steps except after i pull the two slide locks, i pull the trigger and the slide releases, didnt realize the trigger needed to be pulled so that's why i couldnt get it to release, the video i watched before i found this channel didnt mention that

We can have any firearm and any mag capacity. And we just passed the stand your ground law. I think it's upsurd that only LEO's can own Gen 4 and Gen 5 Glocks but not the public. They do realize a Gen 3 can kill you just as dead then a Gen 4 or a Gen 5.

I am unable to remove slide on glock 23. Trigger is not stuck. Gunsmith had removed the plate on back pulled the striker out. He said he had to 'reposition' the recoil spring/slide rod. I guess he had to use a long, slender tool to do so. Anyway, he was able to release the slide and even did a couple times. When I arrived home I was unable to remove the slide - I have disassembled and clean this gun MANY times. I am unsure how this recoil spring gets out of position.

[@SansBinky]

Is it normal for my striker or firing pin to protrude from the face when I have the slide locked to the rear? I'm able to push it back in with my finger but it seems loose. has about a 16th of an inch of room to wiggle in and out of the breach face when the slide is locked back.

Everything is simpler - the barrel muzzle has a very large impact on accuracy. To protect the muzzle from damage, it is usually treated as a muzzle chamfer - the crown. Thanks for video! When will be released Glock 22 gen 5 ??

[@johhnyjak]

27:12 This is a mistake - extractor does NOT skip case rim in a standard loading cycle. Case slides up the breech face right under the extractor hook. But extractor has indeed small motion while this happens.

Is it possible to put the firing pin safety in the wrong way. Or do the cutouts on it mean it can only go in one way? The design is different from the gen 3 I noticed. I transferred my internals to another slide and now I’m paranoid I didn’t install it properly. It does pass function check though and blocks the firing pin so I guess all G?

Can someone help me? I’m not great with re assembly. I just bought a new Suarez slide for my Glock 17 gen 5 And I needed to transfer all of the firing mechanisms from the original slide. I was struggling for almost two hours but I finally got everything on. However as soon as I got the back plate on (which was a struggle didn’t have the best tools) the safety plunger fell out. I have it. But I’m frustrated. Am I making a rookie mistake? Do I put the extractor in first THEN the plunger? And does the plunger go in sideways? Im sorry im New at this and forgive my rookie questions.

[@ES4406]

Does anyone notice that the firing pin floats around when you pull the trigger or when the slide is in the locked position? Is it because of the new plunger design? My gen 3 30 SF doesn't do that.
