Can someone verify this for me? Is it true that a Glock 27 (.40 cal) can be converted to fire 9mm by simply changing barrels and using a 9mm mag?

I don't own a Glock....but if this is true...this may be the deciding factor in switching to a Glock 27 for CCW. (I was also considering the SW M&P .40 cal)

This sounds to good to be true. Please shed some light into this.
 
How would it extract and eject? I would think you would have to change out either the slide or the extractor when doing the change to 9mm to make it work right. Oh, and what about the recoil spring?
 
Friend of mine has a Glock 27 and Lone Wolf 9mm barrel. Yes it does work, and works well with factory ammo. Just get 9mm mags.

And the 27, bring in .40, can swap a .357 Sig barrel without a mag change.

Plus, if you get a AACK .22 unit, as I did for my Glock 26, it will then shoot .22 LR. Just do as I did and get 4 .22 mags while you order the kit. That way no stopping to reload mags.

I've now fired over 500 rounds of Remington Glolden bullets without one jam! Yes I clean it after each shooting session but it works fine. Just swap slides and mags and you have a .22.

And yes, it works with the 27 and Glock 33. They also make AACK units for the 19/23/32 frames and 17/22/31 frames.

What Reaper said. It's true 9 and 40/357 used different ejector but it will be reliable enough for range use.

I have a G22 and a G23 both has a Lone Wolf conversion barrel for them and they work great. Just the conversion barrel and right caliber mag, nothing else.
 
The versatility of the Glock platform and the availability of accesories have me seriously considering purchasing a Glock even though they're not my favorite pistols.

If I bought a G30, 10mm barrel and .22 LR slide/barrel, I could replace three guns that I already have and have the same MOA.

not just glocks.

almost any .40 S&W pistol can be converted to 9mm with a barrel, magazine, and maybe a recoil spring. the more common the pistol, the more likely parts are easily available.
 
yes you can convert glocks like is said above, as well you can convert xd's as well, as sigs, and i am sure there are a few others but those are the ones that i have first hand experience with.

additionally i have seen a 9mm xd using .40 mags as well. so in a pinch, and if the gun was just for the range, and you had a .40 xd, you could get away with using the mags you already have and 9mm barrel.
 
I have a GEN1 Glock 22 that I put a 9mm barrel conversion in and feed it with G17 mags.. Never had an issue in over 500 rounds. I also upgraded to a captured spring assemby and a 3.5lb trigger conector.
 
No other slide, extractor, springs...nada.

40 to 9 requires a conversion barrel and 9 mm mag as stated, 40 to 357 only requires a 357 barrel.

Works perfectly as described.
 
You need a barrel that is specifically designed to be a conversion. It is not enough to just obtain a stock G26 barrel for your G27 and simply drop it in and start shooting 9mm Luger.
 
if you start with a compensated model, you can buy non-compensated barrels too. 6 guns in one.
 
I just got one of these Lone Wolf conversion barrels for my 33 and a 9mm mag. It works perfectly. Got the barrel for $99 from Cheaper Than Dirt.

The reason it has to be a conversion barrel is that the slide on the 27 and the 33 have a larger opening for the barrel. the standard 9mm barrel would rattle around. The conversion barrel therefore looks like a bull barrel, very thick. Oh, the barrel is also about an inch longer than the slide but looks pretty cool.
 
The Lone Wolf conversion barrel for the 27 is the same length as the stock barrel...

Check the fine print near the bottom of the page. It is a standard length barrel and therefore extends an inch in the 27 and 33. Sorry, I'm too lazy to post a picture. The GNS 141 seams to be the shorter length, but the catalog doesn't list it for the 33. I didn't check out the possibility of using it instead of the 140 listed. I understand that the OP was asking about the 27 conversion but I was just relaying my experience with my 33. Sorry if I confused the issue.

I shoot both my G23 and G27 with the Lone Wolf 9MM conversion barrel for the G23. That is all that needs to be changed out. I use my G23 and G27 mags and they feed great, no need to spend more money on G19 or G26 mags.
 
Not all aftermarket "conversion" barrels are "drop-in" - some require hand fitting by a gunsmith. Lone Wolf is a true "drop-in" conversion barrel.

Most often, with other models of guns with conversion barrels, people have problem with extractor not grabbing enough of the 9mm case lip to extract reliably. I run Lone Wolf 40-9 conversion barrels in my G22/G27. 40 Glock extractors won't fully grab, but will grab enough of the 9mm case lip to extract the case. I have shot tens of thousands of rounds through the LW conversion barrels and they have worked very well.

As to magazine, newer 40 caliber Glock magazines mostly work with the conversion barrels, but the older magazines have some feeding problem (maybe due to the magazine follower design/tension of the spring). If you run into feeding problem, you can try changing the follower/spring or just use 9mm magazines. I run my G22/G27 with new factory magazines with no feeding problems.

The Lone Wolf barrels are match grade and have conventional land/groove rifling instead of Glock's hexagonal rifling. The chamber is just about the tightest I know compared to other factory barrels and the case support is very much improved over Glock's loose chamber/deeply cut in ramp area. For reloaders, this stresses the brass less and eliminates the dreaded bulged "Glocked" cases some people have hard time resizing. The better supported chamber and the conventional land/groove rifling is better if you shoot lead bullets.

I use the LW 40-9 conversion barrels to transition shooters from 9mm to 40S&W and the conversion allows for much cheaper practice option, especially if you reload with lead bullets. You do not need to replace the recoil spring as they are the same for 9mm/40S&W. I load my 9mm fairly hot using Winchester jacketed bullets to mimic mild 40S&W loads. For plinking/range practice, I use 125gr lead bullets with moderate recoil.

So, is there any down side to this $99 (Cheaper Than Dirt) conversion that gives you match grade stainless barrel? The only thing I can think of is that depending on the powder charge, the 40 Glock extractor will leave a small dimple or indentation on the bottom of the case. So far, I have not had any issues with this. Kinda like having a built in reload stamp into your 9mm cases - count the dimples to see how many times it's been reloaded. :D
