If you're going to carry I think I'd stick with the Glock barrel but otherwise the LW is fine.

 

I went with a OEM Glock 32 barrel for my Gen4 23. By doing that you're legitimately making it into a G32 as all the other parts are identical. I bought Glock 32 mags as well, checked for reliability, and it ran perfect. It became my new carry gun.

^^THIS^^
I found a OEM G32 barrel in GT classifieds! I've been looking, for a while. I am really excited to shoot that round!
I ordered a 32 mag, for my 23 and a 33 mag, for my 27.
I plan to carry the 32 barrel, if I perform as well as the 357SIG! :supergrin:

 

I've never measured the inside diameters of the chambers on any .357 Sig barrels, but I have measured the chambers of various 10MM barrels, (same diameter case) so I think I can add something. Glock OEM 10MM barrels have chamber diameters about .006" or so larger than the diameter you'll usually measure in any of the aftermarket barrels, whether it's a LWD, Bar-Sto, whoever.

The aftermarket barrel makers usually claim that because their chambers are tighter, you're cases don't get abused as much when firing, so if you are a reloader, you'll get more life out of the cases. There's also the belief that tighter fitting chambers will shoot more accurately because the bullet is lined up with the bore more accurately before firing - don't know if I think it's true or not (in pistols anyway), but maybe. Glock OEM chambers are looser because it's supposed to lead to more reliable feeding. Simple as that.

Because of Glock's apparent belief in looser chambers, many people only shoot their aftermarket barrels at the target range, and stick with a genuine Glock barrel for cop duty and CCW. On the other hand, I have both Bar-Sto and a LWD conversion barrels in .40 S&W and 9x25MM Dillon for my G20, and neither has ever jammed the gun once, but the original 10MM barrel has jammed many times!

Ultimately, barrel swapping in a Glock pistol is a deal where the individual results will vary so widely that unless you do a lot of testing with your new barrel - even if it's a Glock OEM one - you'll never really know if you can trust it or not. If I was a cop I'd never carry any converted Glock on duty until I'd put at least 1000 trouble free rounds through it, no matter who made the barrel.

Either way you go, this particular conversion should work out very well compared to the ones that change case & rim diameters without changing the slide, extractor & ejector.

 

I put a LW .357 SIG barrel in my 23. Works 100% and is very accurate. I put the barrel on my 23 as it would not function when I attached a light. Works 100% now with the LW .357 barrel and light attached. Go figure.

 

Thanks for the answers. After doing research on the .357 SIG, though, I really wonder what it is that really attracts so many? In the world of "man stopper" the only thing that the .357 SIG seems to offer is higher velocity and penetration. But isn't "over-penetrating" something everyone seems to warn against? What is it about this round that people like? I get the passion for the .45 ACP and even the scarey 10mm Automatic, but where does the .357 SIG actually fit (in your heart?). Why do I need to splurge for a barrel where the loads can be a dollar-per-round? Enlighten me. What did the US Secret Service see in the Glock 31, 32, and 33?

 

I like the Glock barrels because the polygonal rifling is nearly impossible to wear out; they'll last forever. just a thought.

As far as .357Sig love; I always liked the idea of a bottle-necked cartridge in semi auto pistol. I like the flat trajectory, accuracy, and quick target re-acquisition due to the faster slide velocity. It's cool, give it go, you can always sell the barrel easily if it doesn't float your boat.

That's as good a reason as any! And that will be the same reason I end up picking up a 10mm some day soon.

As it's been written before in other threads the 357 sig round mimics the 357 magnum for the most part. It's exceeds 40s&w ballistics both muzzle energy and velocity with less snappy recoil. I don't see why a person wouldn't carry 357sig unless they just can't accord it. Pound for pound it's a great caliber.

I am sold!

 

$25 bucks less for me...

I priced them a few weeks ago and
LW/357 barrel = $125
Glock G33 = $150

Since the gun is for SD this was a no brainier.
I got the OEM barrel and haven't looked back

 

Go with the Glock barrel, the only reason to use a barrel with lands and grooves in a Glock would be to stabilize heavy hard cast bullets like I did with my 20 & 29. I was amazed how much the groups tightened up shooting 200 & 230 grain HC DT's. Plus you get higher velocities with the polyoganal rifling.

I will probably go with a LW .40 for my 32, since I will use it just to shoot .40 on the range.

 

Your not gonna live long enough to shoot out a LWD barrel just because it has lands and grooves. They make awsome barrels and quality is just as good or better than about any factory barrel. I have 3 in use and trust my life to them with 100% confidense. With a good sig HP overpenetration is a non issue.

 

I have a G23. I also shoot LWD barrels in 9mm and 357 Sig in it. No mods to the gun. I use 9mm mags with the 9mm ammo, Glock and KCI. My gun is fairly new and occasionally stovepipes with WWB 115gr 9mm ammo. It shoots 124gr 9mm just fine. When the recoil spring has had several thou more rounds through it, this may be corrected. A sub-compact wil probably experience this even more because their recoil springs are shorter and a heavier weight. I have not experienced any other problems with any of the three calibers and would carry any of them.

The 357 Sig is a cool round in the compact Glock, a recoil flip but with a sort of push also. And an additional note - I believe the LWD barrels have fully supported chambers... Not that it makes any difference that I can tell. They also have lifetime warranties for those who think they can shoot them out, lol.

I think that for the money, these LWD are a good choice.

 

I bought the Lone Wolf 357sig barrel for my G27. It has never jambed with over 1000 rounds through it. I do carry it sometimes, but that damn cartoon wolf on the barrel hood has to take 100 fps off the speed of the bullet coming out of it. Plus when people see that comic book wolf on my gun they ask if my parents know that I'm pretending to be a detective with my toy gun. Just saying...

 

I might get a Wolf or Storm barrel just to remind me I have the .357 barrel in there and not the .40. Is that a dumbass reason? A visual reminder?

 

That's a good reason , IMO. You can't go wrong either way. At the time I bought my first barrel, Glock barrels were much cheaper ($129 I think). I also later had a KKM .357Sig barrel.

It does help you identify quickly what barrel is in the gun. My 9mm & 357sig barrels look the same & more than once I've loaded full mags of 9mm into the gun with a 357sig barrel in it. Not a good combination.

...Oh & I don't really mind the wolf head that much. I just like to gripe about it.

Not really...I've been thinkin' about getting a LW 32 barrel for my Gen4 G23 and some G32 mags, but the ammmo is more expensive. I'm not sold on the idea if it's worth it. :dunno:

 

Lot of good information and advices in this thread. I converted my G22 to .357sig with Glock OEM, just to stay close to the original configuration but LWD barrels are great, I got one to go from .40 to 9x19 and I love it.

Before you buy OEM check if it's "compatible" with your frame by calling Glock, in my case they had warning that it will not work properly if my frame is so and so prefix, I forgot what, but this info is available and not necessarily applies in your case because of the compact frame...just an idea, to check before you buy OEM barrel...

I usually mark the mags with "9" when I use them with my G17 slide or my LWD 40-9 barrel, otherwise you could easily mark the barrel markings with the white crayon, but it is a good idea to be able to check visually what setup is in your gun.

I found the cheapest OEM prices in Glockmeister, here is a link, I believe the S&H is additional to this price. ( http://www.glockmeister.com/G32-GLOCK-Factory-Barrel/productinfo/G8665/ )

You probably have to look into LWD if you reload, as they mentioned earlier, you'll get more from your brass with fully supported chamber of aftermarket barrel, but it's up to you for decision.
.357 is a great round, flat shooting and very powerful, with the right load it really mimics the .357mag, also mentioned earlier in the thread...
I had some concerns about overpenetration, but with the right design of the bullet I wouldn't worry about it as log as it guarantee good barrier material penetration...

Good luck and let us know how you did...with some pictures possible...

 

Thank you, .38! I will be getting the OEM .357 SIG barrel for my 23. Is there any advantage to getting a full size 31 barrel instead of the 32? To maximize muzzle velocity?

 

If you want to get a full size OEM barrel, you have to go with a conversion brand barrel. The full size OEM G31 has different lugs on it and wont work in your 23. And yes, you will gain a little velocity.

 

Just get the OEM 32 barrel.
