Glock 22 to 17: do I have to switch ejector housing?

Which conversion barrels do you prefer?

I have been using KKM/Lone Wolf conversion barrels for my Glock 22/23/27 for many years and recently added Tactical Kinetics with good results. They have all been reliable.

As to replacing extractor, 40S&W extractor is long enough to engage the rim of 9mm cases and extract reliably and I haven't had any issues with my conversions.

With Glock conversions, you only need to replace and barrel and maybe the magazine. I tell people to first try using 40S&W magazines for 9mm and if they experience feeding/chambering issues to buy 9mm magazines.

As to preference, for general range blasting, I would say go with the cheapest conversion barrel as my $80 Tactical Kinetics barrel has worked reliably with good accuracy. My Lone Wolf barrels I paid $100 for have also worked reliably as $180 KKM barrel.

But if you are looking for greater accuracy, KKM barrel with slower twist rate of 1:20 has produced slightly greater accuracy over the years compared to 1:16 of Lone Wolf (typical of aftermarket match barrels) and 1:10 of Tactical Kinetics (Glock uses 1:9.84)

If you are looking to reload, this reference thread on leade length and max/working OAL specific to bullet type may help you with your barrel selection - https://www.thehighroad.org/index.p...let-max-working-oal-col-for-reference.848462/

KKM conversion barrel showing longer leade/free bore to allow longer OAL, like for 9mm Major


Lone Wolf conversion barrel showing shorter leade which requires shorter working OAL for some bullets


Tactical Kinetics conversion barrel showing shorter leade which requires shorter working OAL for some bullets

All I changed in my Gen 2 Glock 22 was the conversion barrel. I use the 40 S&W magazines and have never had a problem as long as I load one less round than it will hold. Good luck, you should be able to get a barrel for less than $100.00.

I got mine from Lone Wolf also.

You just field strip the pistol, pop in the special conversion barrel, put the slide back on, insert a G17 mag, and "Bang!", you're shooting 9mm.

I was unaware of the conversion barrels, but a board member mentioned them to me when I posted about buying the surplus G22.

OK, I’ll ask, why not just trade the G22 plus the cost of the LW conversion barrel in cash for a decent G17?

Plus the option to throw a 357 barrel in. 3 calibers. One gun. Less then 500ish. Can not argue with that

.Can you get a decent 17 for under $400? And would you have 2 caliber versatility after you made the trade? No

In fact the early Gen4 G22 I once owned & bought used was the one of the most unreliable troublesome pistols I ever owned. I still feel sorry for whoever got stuck with that dogpile when I dumped it.

Now the Gen3 17 I’ve owned for 10 years is the exact opposite, probably the most reliable gun I own with tens of thousands of rounds downrange. And I could get another one for around $450.

I put a conversion Glock 22 ..... 9mm barrel(Brownell) in my Glock 31 357 SIG .... barrel only .... changed nothing else .....shot it quite a bit ...

I may pickup a cheap 40 S&W Glock 22 barrel and have a three cartridge gun ....9mm, 357 SIG & .40 S&W....

I have swapped 9mm and .40 top ends between frames without changing ejectors or extractors with no issue. I’ve used several 9-40 conversion barrels, again without changing anything in the frame.

Occasionally you will get one that throws brass in an odd direction (like back at your forehead). And changing the ejector usually clears this up. But it doesn’t happen every with every frame/barrel combo, so you would have to try it out and see.

I have used barrels from Storm Lake, Jarvis, LW, and Bear Creek. The surprise was the $47 .357 Sig G22 barrel from Bear Creek, which shoots better than about any other Glock barrel I’ve ever used, ORM or aftermarket.
