Would like to see a bench accuracy test between stock and DD barrels. Thanks for the great videos.

Buying accessories for my Glock is much the same as the wife buying accessories for the house...….we both enjoy doing it, loads of enjoyment whether we need it or not. Lenny makes buying Glock accessories exciting, fun, entertaining and just makes us feel good about being in this wonderful hobby. All of my stock Glocks are capable of shooting better than my meager skills enable me to shoot but, with Glockstore enhancements I can daydream of shooting teeny tiny groups.

I never had an issue resizing or reloading brass from a Glock Do 9 and 45acp

Bullets not feeding properly with my new double diamond barrel (glock 43) I doubt I'll attempt phone support again...

Hickok 45 uses stock Glock barrels too shoot a G23 40cal & hits a target at 240 yards . Stock Glock barrels are capable of very accurate shots.

Just want to say thank you Miguel for doing a good job explaining everything to everybody on points that they don't really understand

Please start stocking a 6" 10mm barrel for the G20. The Glock version is quite pricey and I'd be interested in a double diamond one.

I only bought a Double Diamond conversion barrel. Because my 31 is a .357 sig. Which is expensive as hell to shoot at paper. So I grabbed 9mm conversion barrel. My stock glock barrel does NOT need to be replaced. It is perfect. It is usually the shooter that sucks.

But a stainless steal on all black slide looks sweet!

Good lesson on barrels. Thank you.

Thanks Lenny!👍 I really learned a lot from this video, well worth watching!

"...and the lead is hard to remove." WHAT??? "Consistency is accuracy." WHAT??? "With a Glock barrel you'll shoot 5 inch groups." Lenny, if you are shooting 5 inch groups with a stock barrel then I've got news for you--it ain't the barrel!!! Last week I wanted to try the Glock 42. It was a stock gun, with no upgrade parts, save a extended mag release. A factory gun with a factory barrel. I shot 20 rounds and got a 4 inch group--at 30 YARDS!!! 5 inch groups my ass. There are a few things you can do to accurize the Glock, and I've learned most of them through time and HARD WORK. And the very LAST thing I would change is the barrel. I defy Lenny to shoot to such a high standard that he requires a better barrel. Look, I've been there. Take a good long, HONEST look at yourself. If you aren't shooting as well as you think you should, then take all that hard earned money that you'd spend on a barrel, or goodness knows what else, and spend it on QUALITY training. It's like golf. You get into it, self-taught, and you aren't doing so well so you go out and spend thousands of dollars on the absolute best clubs made. But they are designed to give an EXPERT just 1% more performance. And that's important if you are a professional golfer at the very apex of competitive golf. In that position just 1% might make the difference between winning and losing a crucial game. But let's be honest, I could have the best clubs known to mankind and Tiger Woods could have 3 clubs (a wood, a 9 iron and a putter) sold at K-Mart 20 years ago and recently acquired in a garage sale. What do you think will happen? Yeah, Tiger Woods is going to DOMINATE me all day long. The clubs don't make Tiger Woods a pro. It's learning from the best players out there who will spend some time teaching you to play better. And then practice, practice, practice. And, as with golf so go guns. You need to find a pro (or at least someone who knows the basics as taught in the NRA Pistol Instructor class) and listen carefully to them. Then practice, and when you are making ANY mistake, slow down and work through the problem. What did the instructor teach you about that? Work out those bad habits. And when you find someone better than you, see if they will give you some pointers. And be polite, humble, and thankful. I've often offered to assist someone who is struggling. Some are humble and listen to what I have to say, and do better. Others keep telling themselves that it's not them, it's the gun. If they will agree to it, I'll take their faulty gun and shoot the center of the target out with it. 99% of the time when people think it's the gun, not them, IT'S THEM!!! And most people have a LONG way to go before they need to worry about the accuracy of their guns. And when you get there, proceed slowly and carefully.

great stuff lenny.you guys have some very nice combos for our glocks,saving i am.

Lenny, I hope you live long and prosper; thanks for your commitment to the 2A trade.

Great you sold me ordered one for my G20 today from Glock Store ! Mainly for the better case chamber support.

I've reloaded over 20,000 rounds of my personal Glock brass w/ no problems w/ FMJ's. Some of them are on their 20th reload. Although I am interested in this barrel for cast bullets. Looks like an nice product for a decent price.

Lenny, Great explanation as Always!

I'm in the process of dealing with the Glock Store about two 9mm barrels....Double Diamond...right now. Both had a failure to fire ( not unusual as I was using TulAmmo and IWI hard primer rounds) resulting in the slide being frozen and would not rack so as to eject the round. Gunsmith suggested returning to Glock but of course there was a live round in the gun. Finally got the round out of both Glock 17 and 34 at some consternation on the part of armorer. Glock Store is telling me that they cannot exchange as I purchased months ago and have shot it. We'll see........ Be careful with the ammo you shoot.

Those DD barrels are great,I have a stainless 357 sig one,very accurate,feeds well.

Very informative. Thank you.

Lenny love your videos! Wish yall would put a filter on your web sight where i could just pick an individual model and it show all the parts available. Would save so much time and make shopping easier. Sometimes i see a video with a product and have a hard time finding it. Just a suggestion, keep it up brother!

Thank you Mr. (Magic hands) Magill dropping knowledge on us.

I have a lonewold extended ported barrel on my Glock 22 in titanium nitride I ordered from Glockstore and I LOVE it. I'm seriously considering a standard replacement for my G27 EDC. Hella great bang for the buck! The Pyramid trigger in my G22 is killer too, by the way.

While everything said in this video is true, it is also true that operator skill, rather than weapon tolerances, is the greatest factor in accuracy. A skilled operator with a sloppy but reliable weapon will likely get better results than an unskilled operator with a more tightly machined weapon. How well would a tightly machined barrel work on a full auto G18?

you need to measure the external dimensions of the locking areas and muzzle end... that's what determines the worthiness of any after market barrel....

Glock's also known to work well with almost any ammunition brand/make , wonder if with aftermarket barrel that would still hold true, or could it have feed, ejection or other issues?

To re-size Glock brass use a Lee Bullet Sizing Kit.

What about the tolerances on the gen 5?

Your videos are always GREAT!!!!

very good videos! Thank you.

I hope you prove the critics wrong who say you're slow when it comes to shipping. Ordered a week ago and hasn't shipped yet.⏰

Oh, Lenny! You have been a fount of knowledge up to this video. Are you saying the BARREL's tolerances are looser of the CHAMBER's tolerances are looser. Of course the chamber is looser but I do not believe the actual barrel tolerances are looser (plus its polygonal rifling.). Thus, the accuracy should not be decreased because of the increased CHAMBER tolerances. Please explain if I am incorrect.

I've seen hickok45 hit a gong and even his smaller animal targets at more than 100 yards with just about every FACTORY glock barrel. There is no reason to change out the barrel, besides shooting lead rounds.

Did I miss where aftermarket barrels usually require some fitting on the lugs and or hood? It's not just the tighter chamber that contributes to accuracy.

i shot a stock glock G17 and got 1/2" with Blazer 124grs what you mean not accurate ?

pushes reloading as a benefit yet the website says reloaded ammo voids the warranty.

I guarantee the Glock is more accurate than 99% of shooters that are using them. Your grip, sight picture, and trigger control has more to do with accuracy than your sloppy Glock barrel. Save your cash and buy more practice ammo. Unless you're a competition shooter of course.

Try carb cleaner on the barrels

Thanks!

Well, the better the accuracy the lower the reliability... so if you shoot competition you want to get more accuracy but when you look for a self defense gun you should NEVER use an aftermarket barrel! So, Lenny, whya don't you do an accuracy comparison video? Put a Glock in a vice, use the same premium ammo with 3 diffrent brands and only switch the barrel. Then compare the groups you are getting at 25 yards. THAT would be interesting.

Great review! Buying my 1st glock 32 on Friday and I'm thinking about getting an aftermarket barrel but I'm so confused because of all the brands out there, storm lake ect.. can you give me some advice?

I just ordered a stage 3 or ultimate pyramid trigger with a double diamond dimpled barrel. I cant find any videos of the dimpled barrel.

is the premium double diamond barrel worth the extra cash? or is the money better being spent on ammo and maybe training through instructors?

Lenny can u just copy a glock barrel with the same wide feed ramp and lower tolerances for more reliability but less accuracy? Whitebox ammo jams in yur tight barrels.

You guys should really link the products in the description.. the chameleon barrel option is not available when I try to choose which one I want

Would these work on a Glock 19 Gen 5 4.2 in barrel ?

NONSENSE. An UNSUPPORTED CHAMBER or barrel is not one that is "looser" or necessarily less accurate. It is simply one where the FEED RAMP cuts into the chamber beyond the extractor groove of the case. This makes for a lower feed angle and more reliable feeding of flat nosed ammo, at the expense of not being able to withstand over pressure loads as well or as safely. The disadvantage is that it may blow up in your face and pop the magazine out if the case ruptures. But, it can be just as accurate. As a matter of fact, many competition barrels are unsupported because (1) IPSC/IDPA shooters are fine with round nosed bullets and (2) shoot the lightest loads that meets class rules to minimize recoil anyway.

Lenny can sell !

Very informative. Do you sell 357 sig. conversion barrels for the Glock model 20 gen 4?

Nice!!

Are they heavier than the Glock barrels? I have seen a tungsten barrel and it helped with muzzle flip and recoil a lot in the video but I can not find one anywhere.

Read TIM SUNDLES article on the BUFFALO BORE web site entitled, "Hard Cast Bullets in Polygonal Barrels." Essentially, he says that quality Hard Cast bullets are not the same as Lead bullets, and you can shoot them out of the Glock Hexagonal barrel with no more of a problem than with any other barrel. He explains how the MYTH that you shouldn't shoot them out of a Glock got started. Not an expert myself, just reporting what I read. For dependable feeding in the Woods I think I'd be safer with Hard Cast in a Stock Glock Barrel. Scoring well on the range is a probably a different story.

Are the double diamond barrels match grade or just non-jacketed safe replacements?

Is the Double Diamond barrel more prone to misfeed because of the tighter fit?

Lenny do you not carry the DD conversion barrels for the Glock 27 (40 to 9mm)? I was looking on the site and cannot find them. Also, you may want to check your site. The certificate is coming up bad when you try to go directly to it. Possibly a MIM, but I can get to the site by using a sublink instead of the parent site without getting the certificate error.

Here in our country a glock barrel is almost the price of a whole gun so expensive here

They need to come in red to match my pyramid trigger then I'll buy one for my glock 30SF

Love your videos, but wow, the prices at your Glock Store for many things are just RIDICULOUS! I'd love to shop with you, but no way I'm paying 80 to 90% more for parts and accessories I can get elsewhere for MUCH less. For example, compare the price of Truglo TFX sights to Amazon, or Optics Planet. Also, the Gun Butter oil you use...19 bucks for a tiny bottle? Ouch! You've got a lot of suckers that buy off your site. Keep up the great work on the videos, though. I do enjoy them and learn quite a bit from them.

THOSE harbor freight calipers are unbelievably inaccurate

What is the length of the Gen 4 17 Double Diamond Barrels? As in Australia we have a 17a with a 122mm, which is longer then the US version 114mm

5"inches at 20yards that's not true at all glock barrels are in fact very accurate

Good video thanks.

Where can I purchase a threaded barrel for a Glock 42?

By the way, I do use your (Lone Wolf) barrel and I love it. But, more accurate??

I need a price list.

Glock guarantees 4 inch groups at 50yrds

Do you have ported barrels for g32

It's Glock's unsupported chamber that makes it "unsafe" to shoot reloads. The "polygonal" rifling isn't a true polygonal rifling like in older war guns (MG-42). The barrel leads as much as other barrels. Also,Glock brass isn't harder to size than other brass. Why it's potentially dangerous is because the "Glock buldge" at the bottom of the brass isn't sized down. Any normal sizing die in an average die set doesn't go down far enough. There are special dies to do that so it will chamber properly. All in all, it's expensive to shoot and reload for Glocks...

Got a barrel for the G34gen5?

With the concept of Glocks not being able to use Buffalo Bore Ammo, I have a new GLOCK GEN4 G27 and the chamber seems to have a lot meat. But with your calipers your taught m what really counts. Will a Lone Wolf barrel make to the G27 able to handle the hottest +P anno out there? So with LW Barrels would you say Buffalo Bore ammo is safer in the LW? I CCW my G27 and will only buy +P from Sig, Underwood and Buffalo and want the tighter barrel. Are you saying the AK like workings of the GLOCK will go way with the tighter clearance Lone Wolf barrels? I plan on buying two. One for my CCW GEN27 & the other for my GEN4 G20 next week with a compensator on it next week.

muy bien

Still 99 dollars same as lone wolf how are they cheaper?

what about +P loads

Lone wolf barrels are cheaper than his double diamond barrels. And they have a cool wolf on them.

Those chamber tolerances are absolutely insignificantly small. Stay stick and buy practice ammo if you want better accuracy. Everyone has to have a way to make money, I suppose.

"Polymer 80 made met buy it" -me i would never buy a non threaded aftermarket barrel had they not created a product I've grown to love and shot easier than building steel 1911s.

So put a after market barrel on your Glock, & you will reduce the reliability?

FMJ is pretty chep in Australia it costs me 92$ for 250 rounds

franchise!! franchise!!

How Long douse barrow last

haha...........I can only imagine an officer pulling a Glock with that Lime Green slide...... "FREEEEZE" I mean.....I'd be standing still just to admire it.

Do you even reload? It definitely doesn't sound like it considering your fixation on Glock fired brass being hard to resize...

Does 2 thousands of an inch matter at 21 feet?

That's what she said ....

So you're telling me if I buy a new barrel I'm going to be a lot better shooter, more accurate?😂😂😂😂😂😜😂😂

glock store paint jobs leave a lot to be desired....extended controls came chipped paint job out the box...I'd love to meet the dumbass who looked at it and said yup this is quality send it...the dimpled barrel black paint had good amount of wearing away after 30 rounds...its a good trigger love the trigger so far the tungsten guide rod is good. stick with the silver if you really want a barrel. I completely gutted out a glock 19 gen 4 never fired and replaced with all glock store parts...the only thing I would recommend buying is the pyramid ultra and the tungsten guide rod. the rest looks like cheap Chinese knockoffs...I put the oem barrel in and did another 30 shots no wearing to the point of seeing the chrome underneath like the double diamond dimpled in black shown....I know they will eventually wear away but didn't expect it after 2 15 round magazines. after experiencing the cheap quality on other parts I'm hoping this trigger will last along with the guide rod.

i thought it was polygonal riffling ..

No access to cleaning kits? First rule for any solider especially infantry is you clean your weapon before you eat or sleep. The fire arms combat soldiers use are their lives. They DO clean their weapons.

subscribed!! lol

It's just fine to shoot ➕P ➕P➕ ammo in 9mm with a stock Glock barrel❓

Glock Rules

you are demonstrating how tight are the aftermarket barrel tolerance that will affect the accuracy but you have only compared the chamber dimension which in my opinion will not affect the accuracy. chamber dimension is only for reliability which glock promised. as per glock claim also that their barrel octagonal/hexagonal design makes their barrel tight as possible and seal off the gas from escaping from the bullet so you have a powerful projectile velocity (which that makes improved accuracy also as their barrel is tight based also as per your claim that tight barrel improves accuracy) Now for better comparison, please measure your barrel dimension not the chamber to prove that you have tighter barrel that will contribute on accuracy. I believed also that accuracy obtained from the aftermarket barrel was the tolerance between the slide and barrel so it will not wiggle to have a consistent aim on target and not the chamber dimension. chamber dimension is only for reliability that it will feed any kind of ammo on same caliber of course and also as for supported chamber to avoid brass expansion or even kaboom.. so it will be reloader friendly. and another advantage of aftermarket barrel was their conventional rifling which is land and groove design so you can shoot lead. :)

Just a word of caution for anyone thinking about making a purchase from the Glock Store. Am currently having a difference of opinion with their customer service dept. on the handling of a recent order with them. I will not go into specifics yet, as I am waiting to see if they do the right thing on their own. If not by the end of the weekend, I will then post a full accounting. In the mean time buyer beware.

Isn't it a little dumb to measure a 9mm barrel in inches... Just press the button on your calipers.

3:27 dirty hand gestures

Not that much tighter for the money

4:15 lenny teaches us how to make babies

I believe I need to start with taller sightseeing? Miss missing 😳😭😜😝😛😍🙃🤓🤑🤔🙄👀👁👁💀

Glock functionality is better w/FMJ Remember and like Lenny just pointed out the Glock was designed as a weapon of war for soldiers for use in the military’s which is why it’s not necessarily designed To shoot anything with exposed lead anything with exposed lead is going to leave lead residue inside the barrel and with peoples predisposition to not wanting to clean their weapons after they fire them or use them in a target shooting mode guess what

are these barrels made of of 17-4 stainless steel or t 416 Stainless Steel ?? we know that 17-4 is more superior ...all Glock store slides and barrels are 416 which is a low quality and if they are made over seas I wouldn't trust them
