I recently just picked up a s&w sd9 my slide has about the same amount of tolerance an I was wondering if it’s possible to fix it up the same way?

[@marcs990]

How do you repairs worn rails??

[@nobodysreview6137]

My Sig P220 has side to side play in the slide, the barrel locks up like a vault though. Is there anyway to tighten the slide a little? Thanks

[@mobiesto]

Great educational video! For the smaller glocks i found it harder to crimp down the slide frame, I was able to instead crimp the back rails outward a bit and solved my rattle. Thanks!

[@HotBrass-Lead]

Can you explain how please?

[@johnnyglocks]

Ed I would be interested in knowing how many slides you have cracked and how many times you have actually done this to a Glock as ALL my modifications and enhancements come from experience.

Johnny pls hmu my damn p80 started resetting but is full auto pls help me

[@knightcustombuilds6988]

I've watched an I was highly knowledgeable with striker fire pistols but not Glock I've always run xdm for comp but switched to Glock recently. Long story short I stripped my converted g22 to 17 in a p80 an it's been hell ever since I'm running all oem from backplate to pins everything I don't know where else to turn only thing I haven't done is change angle of crossform . Now do u think I oughtta put the Glock back together and start over from scratch with the pf940v2??

[@knightcustombuilds6988]

I can't give up I gotta get this bad boy straightened out. This is my PC of 2A. And I gotta fix this I know u can help

[@thomasstaples]

Hey johnie, old video but I’m working on a p80 and does one also “tighten” the front rail/locking block as well as the rear rail?

[@Alexa-pe8ie]

Holy cow this is what I’ve been wanting to know for awhile but this is definitely a pro mod...Not sure how I feel about trying this myself haha

[@ilooklikeme7106]

My glocks is new and the slide is loose when you press on it and shake it side do side. Is that good or bad?

[@sevany6581]

Hi Johnny, my Beretta APX has the issue you mentioned - wobbling slide on frame, any video can show how to fix it?

[@firearm.obsessed8142]

How much to do this mine is bad and barrel rattles side to side

[@ronalexander4955]

Most of those slide are 17-4 precipitation hardened. Hitting it would or could put a microscopic crack propagation under the surface. I actually went from a sheet metal back rail (p80) to a solid machined rail on the back to level mine. Mines pretty solid as well...

[@dbc978]

where did you get machined rails? rook?

[@DD-sw1dd]

Considering the thousands of impacts the weakest part of the slide takes (guide rod hole) during functional use over the small contact area where the recoil assembly meets the slide hole cutout, I’d wager these rails aren’t coming anywhere near cracking after afew taps. Especially considering these impacts are definitely not as violent as the impacts induced at the guide rod cutout during firing). This isn’t something I’d ever do. I’d have a gunsmith do it or i’d contact Glock. I 💯 believe JG knows what he’s doing. I’ve only ever seen Glock slides crack when someone drops them on on hard surfaces directly on to the edge of the guide rod hole which is also a MUCH more stress than he’s generating with his ball peen hammer. For reference, the yield strength of 17-4 SS used in these pistols is anywhere between 100,000 to 170,000 psi depending on heat treatment or, if they use 416 SS it’s 40,000 psi. Since the hammer face has a relatively large surface contact area on the rail he’s not going to induce anywhere near that kind of stress. Unlike dropping the slide and having it impact on a single point on the edge of the rounded guide rod hole.

[@billbob6356]

So some guide rods have a bigger diameter wher it sits in the barrel. So have you ever had to take material off of the guide rod? I had to on one I bought offline because it made the gap bigger in my slide. It was tighter because it took up the slack but I had a bigger slide to frame gap and I didn't like that .

[@5jjt]

Does slide tightening generally cause more malfunctions? For example, would you not want to do this on a carry piece?

[@5jjt]

I am interested in doing this method. Does slide tightening generally cause more malfunctions? For example, would you not want to do this on a carry piece?

[@PkwyDrive13]

Wonder if I can do this with my PDP Pro... It has more wiggle than Glocks

[@dougphillips7524]

I have a gen4 19 stock Glock that moves down in the rear when pulling the trigger.I only want too tighten the slide up just enough to take out most of that movement. I'm not afraid to hammer those edges; what did you use to gauge how hard to hit

[@AaronGman]

This is exactly the answer I was looking for. I have a shadow systems MR920 and when I pull the trigger the slide comes up, when the trigger breaks the slide comes down, lots of play, and I can see the sights and red dot move a lot, especially when dry firing. Gonna fix it just like Johnny suggested.

[@nd8504]

How'd this turn out for you? MR920 is my first "glock" and I noticed the take up on the trigger clamps the slide & frame together. I'm afraid to touch it to void the warranty but I'm also not trying to lose accuracy

[@AaronGman]

@@nd8504 I ended up not doing it. I was about to but shadow systems told me to try it with the mag installed. I put the mag in and it does it very minimal. If I have a mag in and a dummy round in, it doesn’t move at all. So it shows me that when I’m shooting it and I have rounds in the mag, it doesn’t move.

[@highspeed9518]

I see in the comments people say braze the tabs how would you do that with a polymer frame? Would it melt and misalign the tabs? And silver solder is very soft seems it would just wear off very fast

[@Caine459]

The back of my slide lifts up will this fix

[@alexduke5402]

💥 *WARNING TO ANYONE THAT WANTS TO DO THIS* I did this to my gen5 19 and after 6k rounds my slide has cracked ON BOTH SIDES where i tightened up the rail with this technique. I didn't tighten it up a lot just enough to snug it a little. I would not recommend doing this.

[@SpecialEDy]

People have been doing this for decades, I've done it to a half a dozen glocks and never had an issue.

[@JeielElBori]

I Am Having That Same Shaking Problem And (Unloaded Of Course) When I Shake It, The Striker Pin Goes Off And Is Driving Me Crazy 😢

[@cymanca]

I have been mesmerized as Johnny the Wizard shaves off a mm here adjusts the 2mm angle there, tiny adjustments that make a world of difference. When I saw the title of the video , I expected to see another one of his fine precision artist like modifications so I lost my Coke Zero when I saw him banging away with a mallet and a large screwdriver. I have his drop in trigger on my G43 and it gave me the confidence to make it my EDC so I am a big fan .

@@jeltyry he should stop sucking dk. That wasn't obvious enough in my original comment? Lol

[@RangerCaptain11A]

this works on a 1911 frame because the peened area is always contacting the slide as it moves through its cycle. but this method only tightens up the slide in one position. if you moved the slide back an inch it would be loose as before. so how does this increase accuracy?

[@johnnyglocks]

Because of the solid lock up.

[@cavalieroutdoors6036]

The barrel should be locked until the bullet exits the barrel. Only after the bullet leaves the muzzle will the slide start to move backward & the gun come out of battery, and at that point it doesn't matter how loose or rattle-y the slide is because the round has already been sent.

[@geraldgriffin8220]

Like a bank vault ! I'm impressed...didn't know you could get that from a Glock !

[@johnfranks]

I asked about this at Glock armorers school... I was disappointed that this wouldn't be covered in the advanced course. I have some that are WAY loose. I'd like to see this gun perform in a pistol vise vs a stock pistol! Have you considered doing this on a arbor press or hydraulic press for more control over the process?

[@johnnyglocks]

johnfranks I have. especially when it is splayed. I was just 1000 miles away from my bench so Anvil and Hammer it had to be.

[@nobodysreview6137]

I put an Alpha Work Barrel in my Glock 27, locks like a vault and shoots great, i had to polish the feedramp but its a perfect tight fit. I was amazed

[@TXLoneStar_]

When I let Zev work on my G30sf trigger for warranty work, it came back screwed up. The slide is scraping the rear polymer tabs and not riding the frames metal rail tabs.

[@ReclamationGroupXO]

Johnny I have a question. I have a Gen 3 19 frame with a Gen 2 slide. I was told that those would mate perfectly. But I just tried mating them today and the slide is dragging badly on the guide rails. Any help is appreciated.

[@250rapid]

I tried your "hammer procedure" on my son Glock 17 airsoft because the slide was extremely loose and to my surprise, problem was solved!!..However, airsoft slide are made of aluminum or some kind of a softer metal so it was very easy to adjust with a "smaller" hammer. I will hesitate doing it on a real Glock.

[@jsensei402]

Cool

[@callsignprofessor]

Nice one! Airsoft glocks are made of pot metal or if you get a good aftermarket one cnc aluminum. (ghk glock that will be released is steel!)

[@aperturelabs8552]

That's why no one will remember your name.

[@Grizzlytactics91]

could tolerances be so lose that they make the gun unsafe to fire?

[@KanoDailyThePhilippinesandMore]

I've had Glocks that were just ridiculously loose. Just inserting a loaded magazine into the gun gave you a trigger job. On a lot of Glocks, you can see the slide moving when you pull the trigger. There's no way to achieve repeatable precision on a striker-fired gun's trigger, which has parts in both the slide and the frame, unless you have the slide and the frame in the same location every time. So this is definitely something I always look for in a Glock. I'm not interested in the ones that rattle. I know it makes some people feel cool to say (especially with 1911s), "I always just look for the one that rattles the most, so I know it's reliable." I am always happy to leave the loose ones for people like that.

[@MattyDemello]

lol right! I hear you. same here. I don't mind a very very little movement but not much.

[@Westcoastk00k]

i have the p80sc g27 ( kit) and a p80c g19(from diff site, but the slide from jsp) they work well. got a newp80sc g26, but this time got a slide off ebay from some custom p80build. the slide wont fit on, i dont know if the slide is too small or the rails are too thick for the slide....every subcompact seems too only fit with glock oem slides....u have any problem with that type situation?

[@VendettaNC]

Your problem is having p80 anything. It sucks

[@Westcoastk00k]

@@VendettaNC lol dude this like 5 years old..my four5 is a beauty now...

[@DanaWebb2017]

Be nice if you could do that on an HK USP

[@toobeer]

I did this to my 19's slide except I used a steel block about 2 inches by one inch square to get the exact angle I wanted. Starting off with light taps and checking any movement as I went along, then increasing the hits until I reached the desired results yielded me a perfectly tight slide with no play. Hammering the slide is a well known way of accurizing a 45 ACP. If a Glock slide has up and down movement, that movement plays on the sear to striker engagement and that is not a good thing to have.

[@69ChevyGarage]

I've been wanting to do this, but been hesitant since I am afraid to ruin/damage my slide. The right angle and securing the slide seems key.

[@bidenstoletheelection9116]

@@69ChevyGarage Don't waste your time, It doesn't help accuracy 1 single bit as the sights and barrel are part of the slide, Same reason why a AR15 doesn't gain ANY accuracy by tightening the upper to lower

[@toobeer]

@@bidenstoletheelection9116 But what it does do is make it so any potential upward motion of the slide when you put the magazine in does not lessen the contact relationship between the frame mounted crucifix and the slide mounted striker, which keeps the gun safe by not decreasing the contact between the two as the slide rises. ALSO, if the slide and barrel operate as a unit. Can you be sure that when the gun is fired and the loose slide and barrel (before tightening) move, that movement, even in a very small amount, doesn't take place before the bullet exits the barrel?

[@benmoppin7320]

Can you just bend the rails down instead?

[@69ChevyGarage]

Excellent question, no one has replied.

[@adamlong54]

I have done this to my 7.62x25mm tokarev and my Taurus g2c makes for way more accurate gun . you would be surprised how many people have loose sloppy barrels and slides and think that's how a gun is to be until you hand them your work and show them the difference and accuracy difference.

[@01camarosspower]

Sign me up for the flat face trigger and connector!

[@bruces12]

This is similar to "peening" the rails on a 1911 frame. As he said "crimping", which is using the similar technique to tighten the rails on a 1911.

[@kcampbell4098]

did the same to my 45 ACP

[@wilmingtonperformancediese230]

I need to do this to my gen 3 21sf as It has slide to frame wobble to bad , I can’t trust it reliability to carry anymore . I just don’t want to mess anything up any worse then it allready is .

[@paulmarshall9189]

How long do you expect peening to last on a Glock slide before it loosens back up?

[@johnnyglocks]

I've only had one loosen up and it was after 12,000 rds

[@paulmarshall9189]

OK, that's about 3 months of shooting on my practice gun. I've been reluctant to mess with this in the past, due to the possibility of loosening over time, and then needing to readjust. But it would be a big help to take up some of the vertical play in terms of dialing in a consistent trigger.

[@michaelsorrell601]

I find it hard to believe that with a semi-solid plastic frame with 4 small points only that the slide contacts; I don't see peeing the slide making much sense. A 1911 is another matter.

Awesome info, thank you! Solved most of my slop, good enough for me anyway

[@MattyDemello]

VERY nice. Thank you! I don't mind it being a LITTLE bit sloppy but I don't like it super lose and raddling. This is perfect. So you only warp the slide where the tab area's are? or do you have to slowly little by little do the entire slide?? Thanks! Thumbs up man.

[@royhoggatt9651]

I know this is a late reply, but I would think just where the tabs are. You would really only want the slide tight in battery, that is the only time you would use the trigger. Once it's out of battery you would want some space so there would be no binding.

[@andrenemy47]

Is it possible to do this on a CZ Shadow?

[@ChildofGod990]

Just wanted to let you know. I did this to my 26. It did help the slop but it micro cracked the edges of my slide. Something to consider

[@EpicSprint]

Is your gun cerakoted coated or a factory finished?

[@clintonajayi6275]

Will this tighten the barrel/slide on a p80 frame?

[@gottmituns3225]

The minute 06 : 02 that moment when the flat screwdriver enter in the slide channel i have recall that the channel that loooong slot must be 0.06299 inch / 1,60 mm [ less than 2 mm ] in width out from the G. Gaston's factory...

[@firearm.obsessed8142]

Ya I tried this and it just cracked my rail and it didnt even tighten my slide

[@bigrod0069]

I would much rather try to change the size of the rails the slide rides on, this kind of scares me, seems like it could stress it and possibly lead to it cracking. I'm not trying to say it's wrong or won't work, but I'd rather have to replace the rail pieces than the slide, but maybe this is better

[@CeliaShadden]

I kno you are THE glock guru.. But im afraid of hitting my slide with a ball peen hammer... Is this glock you did this to still running reliable and tight??

Absolutely but you have to remember I was not in my shop in my shop I use brass shims and an Arbor press

[@TheRockmart]

O used jb weld and it worked

[@FierceProtocol]

keep in mind, every time you bend metal it gets weaker. do this with extreme caution. Personally, I would only let Johnny do it. No one else.

[@ontariodoublex2713]

Did this to my gun and cracked the slide probably not a good idea

[@edpenczek5857]

What is not mentioned is the slide coating is extremely hard and does not bend. In other words, it will crack. If you decide to adjust your glock accordingly, be warned. Will this adjustment make your Glock more accurate? Yes, technically, minutely over distance. Is it worth having to refinish your slide if the adjustment is large? Your call. 5 cents worth of free advice.

[@johnnyglocks]

Ed Penczek Thanks for your perspective. I usually only do this if it is absolutely necessary. And as you can see this gentleman's gun is designed for distance shots. Also I have Never had the finish crack but as you said "technically' speaking it could crack.

[@nelsonyepezr]

Ed, what are you talking about? You are thinking about hard paint over a flexible surface, yes it will crack, but that is not how Glocks are refinished. They don't have a "coating" on top of the metal, they have a "treatment" done to the metal that bonds to it in molecular level. It's inside the metal so it will move with it. dont spread ignorance. Google is your friend.

[@vinnier6]

nelsonyepezr no dog in this fight, but the you are correct when you said the treatment is done to the metal, but the black you see is a black coating or paint if you will, so you were wrong on that...

[@gardy90]

Trying to make a glock more like a 1911? Lol

[@forrestyoung6588]

Okay but tightening it up can affect reliability. Also Glocks are very accurate, pistols in general are more accurate then any hand that's holding it. So tell me you why would you do this to a perfectly good pistol?

[@johnnyglocks]

Freedom Fighterz it's a production gun there are big variances in slide to frame tolerance. So it wasn't a perfect pistol and it's lock up was horrible which affected engagement and Trigger action. Maybe you can tell us your credentials and how many Glocks you have worked on?

[@forrestyoung6588]

JOHNNY GLOCKS the persona. Im a gunsmith and an NRA certified self defense trainer. Im also a competition shooter myself. I get what your trying to do. I run compensators myself. I also drop in new triggers, but to be honest the pistol I run right now has a stock trigger with a minus connector. Other than that all my mods are to the outside of the pistol. I know many competition shooters and never even heard of someone wanting to do this to a gun. My glock, stock from the factory shoots 3.2 inch groups with factory ammo at 50 yards. So you cant say that whatever you do to any gun is going to compensate for human error. You will never be more accurate than a stock Glock. So why would you focus on the internals when it's the external features of the gun that are going to help you shoot the pistol better. It's how you shoot the gun that defies how accurate you will be not the internal mechanisms of the pistol itself. At least not in a quality made pistol like a Glock.

[@forrestyoung6588]

JOHNNY GLOCKS the persona ... also I own 16 Glocks. So I think I've worked on a few.

[@johnnyglocks]

Freedom Fighterz I don't have too too much time to debate this. You have valid points and I have worked on Glocks in the thousands and there are guns that need work to the internals that most people don't think about. so I guess you can call it innovation through experience. I guess nothing should be done to a gun internally to enhance it. What if I put a 10 x scope on a top of my glock. It's going to enhance my sight picture which is a huge part of shooting and it's an external enhancement but it's not practical. However there is a middle ground. In all my videos I always stress unless it's necessary "less is always more." There are sleuth of competitors that do this to their Glocks I'll refer you to Robin Taylor's book titled The Glock in competition. It's a great read and you can hear about stuff competitors do that is just seemingly crazy. Like cutting a 45 degree angle across the striker and matching that angle with the Seer because the trigger bar has a inclination to rise up and to the left. If I'm doing something with a Glock it's from experience and A Lot of it. I really do appreciate your perspective so don't think I'm being disingenuous or cocky or anything. There's no way to learn unless I remain teachable with very little ego.

[@forrestyoung6588]

JOHNNY GLOCKS the persona well it most certainly seems like you know what your doing. As long as the end user knows the benefit and possible consequences of any modifications I don't see issues with it, even if I don't understand why. Its seems like your experienced and im not doubtful of the quality of your work. Just a note to anyone, if you want something like this done, maybe have a gunsmith go at it. Experience is everything when it comes to advanced modifications. Get some sort of a warranty so if they muk it up, its on them.
