So what I learned from this is to stick with the factory glock barrel.

My brother is thinking of the L2D and this helps. Thank you for your time and wonderful review

Bullet "wriggles" in Glock barrel - "That can hurt accuracy". Bullet "wriggles" in L2D barrel - "That's good for reliability".

I learned quite a bit about barrel quality and how to judge the quality of a handgun, Thanks!

Just watched this video and learned a lot about what to look for with barrel fit. Thanks for the info and keep up the Great Work, Graham!

I'm fairly new to Glock and your well presented video just caused me to subscribe. Thank you, for sharing!

Funny that when it comes to chamber fit, the movement of the round in the chamber "can hurt accuracy" with the stock barrel. But when it comes to the L2D barrel, that same movement helps with reliability and has an overall better fit, proving that this barrel is far superior to all the others. But remember, it's not biased. Not saying L2D isn't a good barrel; I'm just saying you be honest that you're doing an infomercial instead of making it look like a head to head challenge in which L2D is clearly the winner. If it really was the case, name the other barrels.

Really good video! Thanks for your time

rigglr wroom?

great video explains a lot thanks for the knowledge keep your videos coming

Excellent detail and presentation. Easy to follow and also unbiased. You just earned a new subscriber :)

Great presentation with real facts as shown.

this is a excellent video, very detail oriented

FWIW: I believe that Glock starting adding the forward bevel to the Glock 19 barrels after NYPD began to have their infamous Phase 3 malfunctions. Early Gen 2 G19 barrels do not have this bevel.

Good video, you made some points which are very relevant when choosing a replacement barrel. I didn't hear you mention anything about rate of twist. I'm NOT at all claiming to be an expert but in my limited experience with aftermarket barrels the rate of twist and rotation makes as much difference in hits to misses as a good lockup. For instance, many "match grade" barrels for Glock 19 have a 1:16 twist, which, in my opinion, is way too slow for standard weight and velocities. I think you would agree that a 1:10 or even 1:8 is much better for match accuracy. Some shooters have no particular preference in left or right twist but I prefer a left twist, especially with heavier loaded ammo. The left twist helps me as a right handed shooter in getting the sights back on target after each shot.

Nice explanation on what to check.

Gonna hit the site up. Thank you for the video 💯

lol is this paid add for that L2D barrel ? because it totally sounds like one...

I think this was a great in depth vid. Thx sir!

I just bought one of these L2D threaded barrel for my Glock 19X. Can't wait to put some rounds through it.

Great video! Very informative👍

Awesome video Again n Again...

Great video. nice info.

Nice~ Would love to see a comparison between the L2D barrels and KKM and lastly Barsto... However, Glock's have improved their barrels quite significantly with their new "marksman" barrel claims. I understand this video is quite old, but nice review. L2D barrels are not cheap!

Based on lack of availability it obvious that people love to upgrade their Glocks! I was shopping around for a barrel and while there plenty of choices, none are in stock. Thanks for the eye opener!

Would love to see this vs S3F , KKM, and Barsto match. Top brands in the game right now. With real world results too!

Actually, I think that you may have been a little off when it came to demonstrating and/or accepting a certain amount 'play' in the chamber. I sensed that you were a bit surprised at the fact that the L2D chamber had as much 'play' as, for instance, the stock barrel assembly. I believe there is an expectation that, upon firing, the casing will swell to fill the chamber, and it's the extractor that breaks it free from the chamber wall so that it can be ejected. A certain amount of play is expected, and is one of the engineering tolerances built into a firearm's chamber. Even with 'play' the accuracy is unaffected, due to the fact that the projectile has already been partially delivered into the barrel proper. Now, I am not a gunsmith, nor do I play one on TV, so I would welcome any correction on my assertion.

Good info. Thanx!

Very informative and interesting. I have a Glock 40mos that I would eventually like to get an aftermarket barrel of an extra inch or so for a little more velocity and the use of handloading lead projectiles, along with as much accuracy as I can get out of it. 👍👍

Barrel accuracy - I am now at the age where my guns are way more accurate than I am. In a defensive pistol, at defensive ranges, I don't really think it matters much

I replaced all my stock Glock barrels with Lone Wolf I have no negative issues to report no failure to feeds no failure to eject and no more Glock smile on the 40 S&W cases.

Sorry!; I forgot to mention the G.3 Glock frame I used on that Franken.Glock, was a Glock 22 / .40 S&W.

HIIII, I’m Graham Bates, when I shoot... I shoot through L2D BARRELS.... alll day.

Very informative thankyou!

Thanks for the vid! You showed case support from the side, but I'm interested in what the support is like at the feed ramp. Was the L2D more supported in that area than the factory barrel?

Good review. Like you said you pay for the better barrel. I noticed on Wilson combats list that you must have send in your gun so they can fit one of their barrels. It would be interesting to see how this works out. Again it is not cheap. Take care!

Excellent, excellent video. I've always wondered how to choose the best barrel for my 19. I had no idea what to look for. I didn't realize there could be so many differences from one barrel to the next. Now I can make a truly educated decision when I make my purchase. Can't thank you enough. Liked and subscribed.

The glock factory barrel is engineered so as to permit functionality in a combat environment where it would be subjected to dirt, dust, mud etc. if you don’t have to bet your life on it use a “match grade” barrel. Otherwise “ if it ain’t broke, don’t fix it.”

I'm under the impression that most factory barrels are cold hammer forged, whereas most aftermarkets are milled 416 SS. I'm really impressed by the L2D barrel though.

Graham; All due respect, @ 7':07" regarding 'case support' (I'd rather say: Case head support, to diminish 'Kaboom' probabilities, quite common on Glock + other brand's 9x19mm pistols), you can clearly see that given ctg is NOT fully chambered, (Roughly 1/16th" short of being fully chambered), which would lead me to suspect a couple issues: >Either that 'X' bbl is short- chambered, (Gunsmith- fit bbl??, just like some Custom barrels). Or.. >The 'X' brand bbl has a shorter 'leade' or throat / groove starting distance. Why I am thinking of it??. Well, I've been a shooting competitor, (USPSA / IDPA among other disciplines..), since mid- 1.990's. In fact, my favorite, (Production Class) revolver is one of my S&W 686-3, 6" bbl, I tuned myself. The other, was a 'Franken- Glock' Gen.3 G17 I myself assembled on a G.3's frame + Custom locking block + 'Lightning' Titanium striker + 3.5lbs connector, and (Believe it or not..) a FACTORY S&W Sigma 4.5" 9x19mm bbl I personally turned down to 'almost' Factory G.17's bbl diameter. (Actually, 0.0025" larger, after polishing it out). Why I did it??; Quite simple, indeed: That particular S&W's Sigma's bbl was machined with S&W's typical FIVE grooved bore, besides being some 0.0015" tighter. (Sigma is long discontinued, probably due to Legal issues between Mr. Gaston Glock vs S&W for 'cloning' his G.17 design /:Patents infringement). All the above said, besides turning it down, I had it's bbl hood and lower lug TIG welded, recontoured / machined + hand fitted (AND re- heat treated) + bore 'fire lapped'. (I'm NO Gunsmith. Just a 'wanna be' ER/ ICU + Medical Examiner, ex- Military MD), sporting / competitive shooter who went into that crazy project, almost three decades ago. The outcome was quite interesting: Groups went from G.17's factory bbls' 3.5" to 4" @ 20 yds, down to ~ 1.75" w/ my handloads. Since It had both 9x19mm + .40 S&W 'kits', (I earned over a couple trophies with said Franken.G-17/22, back in the day..), several shooting buddies got interested in it. Finally I sold that rig when I was relocated to the opposite side of 🌏 due to MD work. Many thanks & Blessings for an interesting review!!. 😇🇺🇲💪🙏🙏🙏🙏

Thanks for the video! Deciding on getting barrel on my G34, how is it holding up?

I'm surprised the gs barrel isn't supporting the case completely. It's the main reason for changing a barrel aside from accuracy. The oem glock barrel doesn't support the shell on the bottom and let's the case bulge upon shooting. Makes resizing a bitch for reloading. The double diamond vs barrel is supposed to be more supportive than stock not less. Odd.

Excellent detail. I learned a lot!

Good video, but you should have mentioned the other barrels. Interesting point to note is the Gen 5 Glock barrels are now crowned. Kudos to L2D combat for being innovative. I also agree with others that In other for this clip to be a true comparison video it should have shown the performance at the range between all of the barrels. Otherwise you open yourself to being perceived as producing a basis video. Keep the videos coming!

You can take all the measurements you want, how well it performs means everything sir. I get yoiu love the L2D barrel and it might be the best, but until it is tested it is just hunches, with a healthy shot of bias.

We used this GRIFFIN on our calling card in VIETNAM 69-70

Man you should apply for a sales job with L2D, you did really well on performance ...

good vid

would have been a much better video if it didn't feel like an infomercial for L2D

Bad ass video

Name the other brands, and not be so L2D Biased and I will pay attention next time.... Im calling BS here.... I own an L2D, ZEV, LoneWolf, Alpha Wolf, as well as Blacklist... Quite a few barrels brands are made by the same folks.. lol.. How to chose, but how does one do so without having the barrels in hand to accomplish these test fitting done in this video?

what are the other companies that made the other barrels? I'm in the market as of now

Other than threads, for ( ME ) I see no need to up grade a barrel, in a glock unless you plan on shooting lead ... again for me ... thanks for the video

Man...again....your degree of DETAIL is very much appreciated by this one !! You really bring a scientific mind to THE GAME. There is a saying that "the Devil's in the details". Well, Graham....you're not afraid to STARE THE DEVIL IN THE FACE and command respect and ACCOUNTABILITY !! L2D needs to SUPPORT YOU BIG-TIME....for You sir...SOLD ME LIKE NO OTHER "GUNNER" ON KZfaq HAS BEFORE !!! That one company who's barrel does NOT give FULL SUPPORT to the round.....should NOT be in business....for that seems MIGHTY DANGEROUS.....eh ? Safety first...ALWAYS. Then, when it comes to ACCURACY...well....those "minor" details....(i.e. crowning the barrel, lockup dimensions, etc) IT MAKES SENSE TO ME.....THAT THOSE SMALL DETAILS....CAN MEAN A WORLD OF DIFFERENCE....when it comes to HITTING THE MARK. 2 thumbs...WAY UP !!

I like the Alpha Wolf barrel

I love upgrades, guns, and shooting. but I get a kick out of people thinking they have to spend extra money to shoot better. I'm not a tack driving marksman, but I generally out shoot most people at the range. spend time at the range with your stock gun and you're guaranteed to shoot better groups than a guy who dropped $3 grand on a glock with some holes milled out of the slide, and a "match " barrel. the more important thing of the barrel is case support for super hot ammo, and rifling for shooting lead. I really like the reverse crowning and chamfer to protect the rifling. not only does it look awesome, especially on 1911s, but it serves a purpose.

Stock glock works perfectly fine for me. I don't need a pretty barrel. Sounded a little biased toward the end but decent review

I plan on keeping all my Glocks with stock barrels except my Glock 20. Got that for 4 legged attackers so I shoot hard cast lead bullets. Not recommended in Glock barrels. Really wish they came with lanz and groove barrels for the 10mm as many only carry that load for the same reason I do. I will do more research though. If it can improve my accuracy with my glock 26 than maybe. I'm not sure if I'm skilled enough to notice the benefit at self defense ranges.

are we allowed to use any of those barrels in ipsc production division?

Nothing wrong with modifying your gun. The first thing I did on my Glock was change out the sights before I even took it out to the range. It shot better than I did. The design is actually pretty plain vanilla, but the tolerances are such that it will work fine for more rounds than most of us will ever care to shoot. If your aim, pun intended is the burn ammo and use the gun for self-defense the factory barrel will be fine. You already spent five to $600 on the gun. Put some rounds through it before you modify it further. One good thing about Glocks is the amount of aftermarket support.

Know what your intention and build is for FIRST....THAN BUILD ACCORDINGLY !!! Everyone talks barrels (and you are 100% correct in what you pointed out)......But...Headspace (projectile fit to land & groove), and a proper 11° crown, with a (tested load acceptance) to that specific barrel. Finding a sweet spot in barrel pressure (type of powder and load) to barrel projectile matching. ALL OF THIS IS important for a Bullseye shooter....70% of it isn't worth beans in the field. TIGHT MATCH tolerances isn't the edge when your off paper...plus a possible jam on a .001" is detrimental.

barrel lock, bushing to Bore tolerance, head space, lowered polished throat, rifling, forgeng..... alot does into a barrel to the 1000's in tolerance. Now to match the timing, round, Recoils spring and magazine spring.......ALOT OF MONEY BUT A GREAT HOBBY FOR ME.

looks like a great barrel, would it requiere a gun smith to entune it to my model 20, or will it just drop right in? also what spring weight would you suggest for hot loads.

I like the vid....Brand x looks like a May be a lone wolf and brand y looks like a alpha wolf barrel.

Love to know what brand X and Y are!

Do you have any comment to make about the clearance between the end of the barrel and the opening in the slide where it pokes through? If you have play there then another factor causing inconsistency clearly exists. I think these clearances, and the clearances between the barrel as it locks in the ejection port both play to how true the barrel is to the sights. After a bit of shooting, with such tight clearances, do you notice any binding as the barrel heats up?

How far will the match grade barrels protrude from the G19 slide ❓

where can I find a G23 Gen 5 silver threaded barrel?

Where did you get The non fluted barrel. I’ve been looking for one but seems like they dnt make it anymore l2d olny offers fluted

Graham, have you moved on from Glock to more accurate pistols? If so, what did you find more accurate?

How well will the Round handle the pressure?

been looking at match barrels and stumbled upon l2d yesterday. coincidentally, I have the opportunity to watch this video. I would like to see how Wilson combat Zev and Agency stack up against this fine barrel

could you review a wheaton arms barrel

What do you think about Blacklist barrels ? looking at one for my M&P 9mm

I have a Glock 34 that I'm upgrading with various parts and I'm trying to figure out which aftermarket barrel is best , well I think you just showed me in this video and wanted to say thanks , I'm buying an L2D barrel right now for my 34 . Great video , this was extremely helpful . ...Bosco

Too bad a lot of manufacturers don't make 10mm Glock 20/40 barrels. That's an application where the build quality would really come into play. Especially shooting heavyweight hard cast bullets.

okay ive done quite a bit of research into glock aftermarket parts. im late to the game iwth a glock 30. but so far i think the only thing worth getting at all is a heavier guide rod. everything else is just... either flare or the illusion of better performance.

Well here's my really angry comment. Great job as always. Detailed and informative. 👍

I would like a very long barrel for my Glock 31 in 357 Sig. I am interested in your quality. But I only see you making 9mm. Is that all you can do?

That is 10 minutes of my life, I can't get back!

By chance the second barrel a combat armory one?

I have a KKM match barrel for my G16gen4 and it shoots less accurate than the OEM barrel. At 25 yards for example the spread for the KKM barrel is terrible compared to the factory barrel. I wouldn't say that match barrels are always better.

True precision my only go to after market barrels

Glock barrel: The only reason to buy an aftermarket barrel i.e a non-stock Glock barrel is to shoot lead bullets &/or to add a suppressor to the barrel. All other reasons are cosmetic & a *big waste of money,* period. Why? 1. The way to shoot accurately is training/practice/ammo = skill 2. Because a gun shoots more accurately than any human being can 3. Glock barrels easily last longer than custom barrels *Don't fall for after-market marketing.*

A few years ago I bought a Lone Wolf barrel for my Glock 23. Recently, I discovered that these barrels are made in Korea and I have no problem with that. I have studied the various videos on aftermarket barrels and their features and compared to the standard stock Glock barrels. I cannot see buying aftermarket barrels unless they offer something that the Glock barrels do not. My biggest concern is that I reload and that you cannot use lead bullets in a Glock pistol. Glock barrels do not have the case support as do the aftermarket barrels. They do allow you to use reloaded ammunition and use cast lead bullets. Case support and the ability to use cast lead bullets as well as accuracy are the primary reasons for buying an aftermarket barrel. AM barrels seem in general, to be tighter in terms of fit. I recently acquired a new gen 3 Glock 19 and ordered another standard Lone Wolf barrel for it. I am NOT going to spend $200 - 250 + for an aftermarket barrel. My price range is $100 - 150.00

Does L2D make a G 36 barrel??

People: Will buy endless doo-dads for pistols, 5 holsters, battle belts, plate carriers. Also people: Shy at a $250 barrel because if you hate it, just toss it in a drawer right? Also (most) people: Spend $0 on training Great vid, I think I'll buy one. Edit: $235.90. Got the stainless one, not because I can outshoot the stock barrel but because RULE 1: Look Cool.

Now I know how to chose, but how do I choose a glock barrel?

So you’re saying L2D barrels are the shit?

what is a match grade barrel? Is it better then one that is not?

I bought 1 from the glock store wouldn't even chamber 1 round. Insane to me considering it's a store that sales nothing but glock parts. Where do you recommend to buy a glock 19 gold barrel from?

A review with numbers is here, L2D did not do so well. www.victorygunblog.com/blog/barrelrace17

How would you say this barrel compares to KKM?

Wow! Tough crowd! I've been a target shooter all my life. The guy is just trying to point out some valid concerns. "Better" is such a vague term. I have target barrels that are bullet/brass/seat/load specific and they are "Better" than the stock barrels...for laser straight, benched, target shooting. Would I use them for EDC? Absolutely not. They're finicky primadonna guns, but I know that going in. You all went after him for not dining the L2D barrel for "Riggle Room" when it's not a binary issue (tight=good...loose=bad) this is the witchcraft of barrel/chamber design. All he was explaining is that there is definitely a tradeoff between ultimate accuracy and ultimate reliability. It's not one way or the other. I took my dad shooting (He was a master marksman smallbore rim fire shooter and basically got me foamed up on shooting) He was a Korean War Era combat Medic. I had a variety of 1911s for him to shoot but I was interested to see which he would pick up and choose out of the bunch. My bet was the DW Specialist...my favorite. He picked them up one by one and rattled them back and forth. The he settled on my old Colt Commander. Sloppy Sloppy Sloppy gun. I was surprised like WTH you're a target shooter? When he saw my eyebrow raised he just said "When your life's on the line, you're not shooting for group." I know this was a long comment. I hadn't intended it to be. I appreciated the fact that he took the time to point out some legitimate differences that many shooters may not have been aware of.

what is it the under 100$ ?

I would considering investing in the L2D barrel if it wasn't threaded.

How about a DOUBLE DIAMOND PREMIUM REPLACEMENT BARREL?

any recommended barrel for a Glock 22 .40 for hollow point bullets?? this is a strict rule as it is for work.

Anyone know anything about Wilson?
