Using factory SAAMI spec rounds, there never was a problem. There has been continual refinement, but not resulting from rampant failure from spec rounds. Older barrels were quite adequate, but not as able to compensate for overcharged rounds or reloaded brass. I've owned and been issued .40 glocks since they came out, and despite heavy agency and personal shooting, never encountered or observed a problem.

EXACTLY!!

The problem was never so much the chamber support as with the ammo. The early Federal cases marked "FC" usually being the culprit. They have long since been withdrawn for the most part, except for a few residuals scattered sporadically in the hands of non LE. There is no such thing as 100% chamber support outside of a revolver as well.

FWIW, I have a new Glock Gen 4 OEM .357 SIG barrel I play with in a Gen 4 G23 and it is superb. To be frank, it shoots just as good as my p229 in .357 SIG.

Body armor is useful against common handgun cartridges, but nearly useless against hi-powered rifle rounds.

Dumb question, and I'm 99% sure I know the answer, but just want to be sure before I buy...

The G32/23 barrels are identical Gen3-Gen4, right?

No, they are not. Gen 4 barrels have a larger cutout for the dual RSA.

Some here have used gen3 in gen4 guns and claimed that they worked fine. BUT. They are different like tiro said. And a phone call I made to glock did confirm this.

Damn. I just compared my Gen4 23 to my Gen3 21 and the cut outs look exactly the same. The problem is I'm the high bidder on a gen3 32 barrel and I plan on possibly using it in my 23 for carry... How is it that on Lone Wolfs website they do not distinguish between gen3 and gen4 when shopping for barrels...???

Different cal. Apples to oranges. There is a difference. I did not say it won't work.

I agree. But I believe all gen3 guide rods have the same width at the aft end. I've done some research online and it seems no one differentiates gen3-gen4 barrels (Lone Wolf, KKM, Storm Lake) at all on their site, conversion or factory. This only leads one to assume that Gen3 and Gen4 barrels are interchangeable, regardless of what Glock may say about the Gen4 barrels being proprietary... Right? I mean, how do you explain there being no difference in any aftermarket manufacturer etc? I'm really confused here...

There is a difference or how else would the Gen 4 RSA fit in the gun? The Gen 4 has a larger half moon cutout.

I have a Gen 4 G32 OEM barrel for my Gen 4 G23. I SPECIFICALLY requested it from Glock and that is what I received. I could care less about aftermarket barrels as I don't use/need them. if you don't believe me then call Glock.

No more questions, please.

I've heard different things...You might want to do a bit more research on compatability.

I was curious after reading your question. I know I had seen this topic before, none-the-less, I googled a bit...On other forums, seems it works with some, yet, others have problems. Aftermarket bbls sometimes are cut a bit differently (nothing you would notice off hand). This small difference may play a factor with their potential success in function.

The Gen4 RSA doesn't fit in a Gen3 because the front end is larger, not necessarily because of the rear.

I think the fact that Gen3/ambiguous conversion barrels are nondiscriminatory between gen3/4 is because of this. The difference is in the slide/front of the guide rods...


I wasn't only referring to aftermarket barrels. Even the OEM barrels sold on these vendors sites are not listed as Gen4... So can you point me to anyone other than Glock who sells a Gen4 specific barrel...?


Oh and regarding the larger cutout, correct me if I'm wrong, but after the gun is assembled, is that not a moot point...?

Sorry, but I'm asking questions because I want definitive answers, not just because Glock says so...

My Gen3 G32 OEM barrel fits my Gen4 G23 just fine, there is no difference. Gen3 barrels will work in Gen4 Glocks.

I just bought a factory g32 barrel from glockparts.com that has the wide notch. It wasnt listed as gen4 but its matches my gen4 23 barrel. The stormlake g32 barrel I bought from midway also fits the gen4 recoil assembly. Maybe all the newer barrels are being made to fit gen4 recoil springs.

KKM sold me the same barrel for my Gen4 G17, as they would for a Gen3 G17. I have had no issues with the Gen4 KKM Barrel.

I take it that the new barrel works OK.

The ONLY difference on SOME barrels is when a .357 barrel is used in SOME .40 cals and then must be ordered by frame S/N. This apparently only affects SOME pre-Cxx .40 cal serial numbers.

My Glock Armorer's parts list/will-fit info reflects no other difference in Gen3 and Gen4 barrels.

Gen4 RSAs wouldn't fit in a Gen3 slide. The barrel half moons are the same and fit Gen3 or Gen4 with the Gen-appropriate RSA in the correct slide. As an example, I have a Gen3 and a Gen4 G17 and the barrels and fit are the same when using the correct RSA appropriate to the slide in which they are inserted.

Thanks SARDG! That pretty much confirms what I've been researching for the past 2 days.

Well, it is sure nice to see a lot more folks coming to terms with the 357 sig. I transitioned to this caliber in a G31 back in 2001 and have loved it ever since. I particularly liked the posts made by GT member English, as usual in this topic and I am also a believer in Dr. Courtney´s work. Some of you should head more over toward the 357 sig. forum.

stay safe all.
