There is a post on another forum that confuses me. On the Concealed Carry/Self Defense Forum there is a thread about Bug-Out Handguns. One post (#77) states the author would take his Glock 17 but would take along his Glock 22 barrel and magazine so he could use both 9mm and 40 S&W with just one handgun. He also states he could just do the opposite. Could you really do either of these two options? I always thought the Glock 9mm barrels and their 40 S&W/357 Sig barrels were of a different diameter. I know you can get after-market 9mm conversion barrels for Glock 40/357 pistols, but I was sure a Glock 17 barrel wouldn't work. Can somebody please help me out with this?
Glock Barrel Interchangeability

The chamber face and extractor (on the slide) would not be optimal in such a case.
Dunno abt 9 and 40, but Glocks easily swap between 40 and 357 SIG with just the barrel.
Among the same calibers, for example, a 19 barrel works fine in a 26, but the 17 barrel won’t swap into a 19.

I no longer have a Glock 17, but I am almost certain that a Glock 22 barrel is too large in diameter to fit into the slide of a 17. A 17 barrel may fit into a Glock 22 slide but it will rattle at least at the muzzle end, and I am reasonably sure it would be an unsafe combination. I can say for sure later this week as I am finally getting a Glock 22, a trader friend is selling his, unfired, for $350 due to the lack of and price of ammo. Prices on full-size Glocks have dropped to bottom dollar around here anyway - unlike the $2400+ that a mint Model 61 Escort went for last night on Crook Broker!
Edited to add, I want to mirror s&wchad's comment about Lone Wolf barrels - I have a 9mm version for my Glock 32. Unless they have changed recently, I have found it to be a high quality barrel which fits perfectly ... now I just need the dinero for a 9mm conv barrel for my Glock 22.

Thanks! Right now I only have one Glock (Glock 31). It was originally a 357 and I got a 40 barrel for it. Works great, as you said. Got a 9mm conversion barrel which also works fine. I don't have a Glock 17, so I can't really check out the 17/22 barrel swap.
OP
Thanks! That's what I thought. Hope to hear more from you later.

You are correct in your thinking. I've owned over a dozen Glocks and can say with 100% certainty that you can't just drop a 17 barrel into a 22, or vice versa. 40 and 357 are just a simple swap. 9mm conversion into a 40 or 357 is just a conversion barrel for the most part. But aside from a 22lr conversion, a 9mm is a 9mm without swapping the entire upper half out.
I just pulled out my gen 2 Glock 22, a gen 4 Glock 17 and a dial caliper.
The 22 barrel measures .590" near the muzzle.
The 17 barrel measures .570".
I didn't try swapping the barrels. The 17 barrel might function in the .22, but I suspect accuracy would be poor with .020" of play. I doubt the 22 barrel would fit in the 17.
I also have a Lone Wolf 9mm conversion for my Glock 22. I've put hundreds of rounds through it using .40 caliber magazines without a hitch. The fully supported chamber is an added bonus, especially if you shoot reloaded ammo.

Thanks! I'm pretty sure my 9mm conversion barrel for my Glock 31 was a Lone Wolf. Mine has worked 'first time, every time' for years now.

Thanks! Pretty sure my 9mm conversion barrel for my Glock 31 was from them. It has given me years of faithful service and really pleased me right from the start because it dropped right in with no fitting required.

Lone Wolf makes a barrel for the G23 that converts it to fire 9mm. Requires a 9mm magazine of course.
Thanks for the correction. It was my original post that had the error in the Bugout gun Thread. Looks like my choice will now have to be my G22 with a additional 9mm Lone Wolf conversion barrel. Thanks for setting me straight.
I just got today a Lone Wolf G19 barrel to install as a lead-bullet-shooter on my G26. It's a half inch or so longer, but it was on sale and I couldn't resist it. Drop-in fit. Ordered it Friday afternoon, they shipped immediately, and I got it this morning. If the barrel's as good as their service, I'll sure have no complaint. Now just waiting for the weather to warm up a bit.
for the record, what the 9 in a .40 conversion barrel does is the bore/chamber are offset .0225 to the right, closer to the extractor. And since Glock .40 barrels have thicker walls anyway, plenty of meat left after the offset.
I have a 23 mos and 27, both 5th gen, and a glock 40 mos gen 4. Waiting on KKM to start making gen 5 conversion barrels for the 23 and 27. Gen 5 barrels are different.

While we are talking about Glock interchangeably, I've heard various stories saying that you can shoot 9mm ammo out of a Glock .40s&w magazine in a G17,19,26,45, etc. Can anyone clarify that?
Lone wolf makes a drop in threaded barrel that works perfectly in a Glock 22. Switch barrels, mags and it works fine. I will try to get the exact model number, I would love to demo for you, but it was -16 a half hour ago. Works with or without suppressor. I have had it for about 8 years. Be Safe,
you might be able to, but 3rd party Glock mags start at under $10, and good ones @ $15.
Not here in Australia. Glock 10 round mags are about $60 AUD each here.
I am only thinking in a pinch, if that's all I could find at the time.

A G22 can accept a G17 barrel and magazine and function as 9mm. Slight variation of muzzle diameter is accommodated by the Glock's lockup - the barrel is positively pushed upward with the slide forward. If you look at the muzzle end of any Glock you'll see the barrel rides in the lower hemispher of the slide opening. Three-tenths of a mm difference between barrel diameter and the opening in the slide is normal and one of the many reasons Glocks are so reliable in operation. When locked up the action is tight, the instant it unlocks all the contributing parts "go loose" is about the best way to put it.
With reduced accuracy and potentially sketchy ejection. Some barrel/slide/ejector/extractor combos seem to work fine, others don't.
No, every change of diameter will change your point of impact and reduce accuracy. In this particular case the change is small enough to not really matter all that much, in a short range working pistol like the G22. To improve accuracy even beyond what is possible with a correct sized barrel in a correct sized opening in the slide, bushings were invented. Precision pistols still use them.
Nothing "Glock" about that. Every modified Browning locked breech pistol works and worked like that long before Glock even existed.
