Looking seriously at a CDNN drop-in 9mm barrel for my G22.3. Anyone have one of these barrels? Those that have converted their 40 Glock to 9mm…do I have to change out my extractor? I do have 9mm mags for use in the G22.
My G22 conversion barrel is from Lone Wolf.
I use 9mm magazines, but I've never changed the extractor.
It works fine, zero problems.
I have used 40-9mm conversion and 40S&W aftermarket/match barrels from KKM/Lone Wolf/Bear Creek Arsenal/Tactical Kinetics for my Gen3 Glock 22/23/27.Looking seriously at a CDNN drop-in 9mm barrel for my G22.3.

... no idea who makes the CDNN barrels. But at $90….seems too cheap to pass up.
You could always call CDNN and ask.I have no idea who makes the CDNN barrels
Yes, you would know "immediately" as spent case/brass flew into your face.According to a friend who worked for Glock, he recomended the Lone Wolf conversion barrel, and said that it MAY be necessary to change the EJECTOR (not extractor). He also said that you would know almost immediately if this was going to be required.
I have Gen3 Glock 22/23/27 and various KKM/Lone Wolf/Bear Creek Arsenal/Tactical Kinetics 40-9mm conversion/40S&W barrels and spent case/brass eject to the right of my face around 4-5 o'clock position.Years back with early generation 3 40S&W ejector face angle caused spent brass to face issue but this has been addressed by Glock with change in ejector face angle to also address when using conversion barrels with 9mm.
I guess that makes sense, seeing as the timeframe of the conversation was just as Gen 4 was coming out, as I recall.Yes, you would know "immediately" as spent case/brass flew into your face.
This was an issue with early Gen3 40S&W models (Using 40S&W and 40-9mm conversion barrels) and since has been addressed by Glock with reshaped ejector face angle.
That is the one I have for my G22. It works.Midway still has the $65 conversion barrels in stock. Quality is good for plinking.

Congrats on the Gen4 Glock 22 and you are welcome for the "deep dive". Due to near carbide hardness Tennifer surface hardening treatment of barrel and slide, buying police trade-in/used Glocks is like buying a pistol that just got broken-in. (I shot 120,000 rounds through my Gen2 G17 with negligible rifling wear to maintain accuracy and another match shooter bought it who continued shooting matches with some spring replacement ... They are tough!)police surplus ... Ended up getting a like new G22 gen4 ... preferring the .40 for my home defense pistol, I like the 9 just fine, have for years.
But these threads make me think I should buy a conversion barrel, and sell the G17. Thanks for the deep dive on this subject.
Haven’t seen that barrel (BCA) that cheap yet, but I’m keeping my eyes peeled so when it goes on sale or price reduced that low I will snag it.I bought the Bear Creek Arsenal 9mm conversion barrel.
The biggest difference in the .40 slide is the width of the top barrel lug and case head slot.
Using the original extractor and .40 mags, the 9mm BCA barrel is half again more accurate than the original Glock barrel. Purchase price was $48.00! It’s also 100% reliable with the .40 recoil spring.
But, I made the “mistake” of buying a .40 BCA “drop in barrel.
It was a whopping “$43.00” plus shipping. It’s twice as accurate as the Glock barrel, shooting 2”groups at 25yds with my cast bullets! I’ve not since replaced it with either of the other two barrels.
It’s a no-name, only stamped .40S&W unit.
I’ve got lots of other 9’s, but it’s the only.40. Likely to stay that way!
I have 2 BCA 40-9mm conversion barrels for Glock 22 (I usually buy spare of many gun related things).Haven’t seen that barrel (BCA) that cheap yet, but I’m keeping my eyes peeled so when it goes on sale or price reduced that low I will snag it.
FWIW, AIM Surplus has G23 40-9mm conversion barrel for $39 - https://aimsurplus.com/products/aimsurplus-9mm-dlc-conversion-barrel-for-glock-23Bear Creek Arsenal 9mm conversion barrel ... price was $48.00!
those were the “blow them out the door” close-out prices. Got them about 3 years ago. I haven’t seen any listed since.
