I know it was 1yr ago, but ammo selection is very important w this setup. Winchester White Box n Blazer Brass or aluminum and other 115gr cheap loads will smtimes not eject and stovepipe or just not rack back. I read that 124gr +p ammo helps the barrel marry to the gun by lining up rails and springs on break in but I think its just finicky w ammo selection. He has a SS or tungsten guide rod in like me so I would love to see him or sm1 (Paul Harrel?) fire several rounds of different loads 115gr-147gr +p and +p+ even to see failure rate. I also have a 10" 357sig match IGB barrel that i put in a standard MCK unit as a bugout experiment. Its ok but im using 40sw mags w 357sig w varying results. Wouldnt trust my life w it but a G19 or plain G22 40sw in the MCK runs smooth as butter and makes the glocks much more accurate thru recoil taming almost completely. The lone wolf 9mm threaded barrel is ammo sensitive and extractor works but the rounds fall on top of ur head in my rig.
It just needs a 9mm extractor & ejector so it will hook/pull the casing better. Everybody will tell you it runs fine without switching it and you can get away with it, but if you want it to actually throw brass away and not come straight back down in the chamber; change them.
I came here to say exactly this. I’m a GLOCK Certified Armorer, and per the armorer manual, there is a stark difference between the geometry in the 9mm and .40 extractor and ejector housing. I’ve serviced a dozen botched 40 to 9mm conversions in the last six months; all of them had extraction problems that were resolved by installing the correct 9mm specific parts.
+Anothercivilian If you want it to fit flush in the pistol a Glock 19 magazine will be what you are looking for. You can also use a Glock 17 magazines, though it will stick out a bit and you can also get the 33 round Glock 18 magazines. You can use just about any model 9mm magazine and it will work aside from the Glock 26 size mags as they are too short to fit properly/lock in.
You should swap both the extractor and ejector in addition to using the 9mm barrel and mags if you're going to rely on it for self-defense. Give it a good 200-round test, too.
Lonewolf used to make a 40-9 conversion barrel for the 27. No other change is needed for fun at the range. If you're going to keep it that way, you'll need to change to a 9mm extractor and ejector. Not expensive and you can do it yourself.
Timothy Padilla no it won't because the outer diameter of the conversion barrel is bigger to fit the opening the the front of the slide on a 40. If you used a Glock 26 barrel it would be rattling around in that front opening
For the most part yes. But a really used mag may not hold them as well and can cause double feeds. I also use my 40 caliber Magazines for my g32 ge 4 in .357 Sig
Just shot my converted Glock 22 Gen 2 yesterday. I was shooting Magtech 115 gr. Out of a box of 50 I got hit in the face 2 or 3 times. I don't want to change out anything but the barrel so that I can still fire 40 S&W when I want. This situation is acceptable for the range but I wouldn't carry with the 9mm barrel without changing all the appropriate parts.
I’m a GLOCK Certified Armorer, and per the armorer manual, there is a stark difference between the geometry in the 9mm and .40 extractor and ejector housing. Contrary to popular belief, and Lonewolf’s marketing, these two parts HAVE to be replaced to avoid extraction/ejection problems. I’ve serviced a dozen botched 40 to 9mm conversions in the last six months; all of them had extraction problems that were resolved by installing the correct 9mm specific parts.
I've heard sometimes you may need to change the ejector to a 9mm, the 9mm ejector has a dogleg bend in it. But I have the lonewolf 9mm conversion barrel in a Glock 23 gen 3 and haven't changed the ejector, and other than it ejecting brass wildly it's worked flawlessly. If it was throwing brass back in my face or on top of my head I would change it, but it doesn't. I'm very satisfied with the Lonewolf conversion barrel. The machining and rifling is done beautifully, I was truly surprised.
I bought the Lone Wolf Barrel a very short time ago and finally got to go out shooting yesterday for Gustav Glocks birthday. The ejector definitely needs to be changed because the shell casings were Landing in my shirt pocket and burning my chest. The .40 cal casings launch.
If the rim diameter of the 9mm is 9.96 mm (0.392 in), and the rim diameter of the .40s&w is .424 in (10.8 mm), why don't you have to swap out the bolt when you change barrels?
I didn’t feel like reading all the comments. But no one changes the ejector???? Omg. Your btf and fte wouldn’t exist anymore. Proper 9mm extractor helps too. But the ejectors are like 1/4” or more different in length!!

You can get lighter recoil springs that make it cycle easier with less hot ammo.

I own a glock 30 .45, i want to know what barrel i need to change it to 9mm or to 10mm? Also witch mag
Is this California Compliant ?
I want to do this but I couldn’t find much about this topic online.
Move to a free state.
This is legal in California.
Maybe issues with recoil spring.
so, what model 9mm magazine would I need for a 9mm conversion on a Glock 23? Thanks in advance.

+Individually Mighty Thank you so much! I appreciate it!
19
I use g19 mags in my 22 with a threaded barrel
@@gotti9234thats impossible g19 mags dont fit in a g22 theyre too short
No need to swap extractors?
Nope
You should swap both the extractor and ejector in addition to using the 9mm barrel and mags if you're going to rely on it for self-defense. Give it a good 200-round test, too.
@@FauxAmis78 I sign that 👍
What about the extractor?
Like to EX 40sw to 9mm in a G27...help ?

Is this ccw level reliable?
Is there a conversion barrel for a 40 cal Glock 27 (Gen 4) to a 9mm?
Unfortunately we are not aware of a 40 cal to 9mm conversion barrel.
I would think a Glock 26 barrel would do the same thing as he shows in the video
Timothy Padilla no it won't because the outer diameter of the conversion barrel is bigger to fit the opening the the front of the slide on a 40. If you used a Glock 26 barrel it would be rattling around in that front opening
Vladimir Lopez you are totally right Vladimir, I was thinking 357 SIG not 40. Kudos
@@timothypadilla8910 The breech will fit and lock up correctly but the front of the barrel will be loose in the 40 caliber "hole".
I have heard that the 40 SW magazines work fine when using the conversion barrel and there is no need to buy 9mm magazines... correct?
For the most part yes. But a really used mag may not hold them as well and can cause double feeds. I also use my 40 caliber Magazines for my g32 ge 4 in .357 Sig
Will this harm the weapon ?
Nope! Just make sure to use a Glock 17 magazine, and you're good to go.
I recommend changing out the ejector because the 9 mm shell casings do not fly very far. They were Landing in my shirt pocket.
Anyone else with this problem? How come my recoil system do NOT fit in my .40 cal barrel but it does with 9mm conversion barrel?
your .40 cal glock came from the factory with a recoil spring that doesnt fit??
What about all the casing hitting your face after the conversion barrel swap?
MAGI CLAW! Recoil spring is the same for g17,22,24,31 9mm and 40sw or a different spring?
I think you have to change the extractor.

What about the extractor an ejector also my G22 won’t extract the 9mm shells with this barrel conversion
Have you guys experienced or heard of any operational problems when just replacing the barrel,thanks

+Dorene Cristler No bolt in a Glock pistol. The extractor will still close over the 9mm rim, grabbing it.
Can I just put a glock 17 barrel on my glock 22
No

Barrel, mag, ejector AND extractor.
Yep, at least you have to change the ejector i think 🤷♂️
