9mm rounds fit into you 40 s&w mag with out modifications? I also have a conversion barrel i just bought 9mm mags.

You will need Glock 9mm mags (Glock 19 mags will fit flush)

[Trainer44455]

what needs to be replaced if I want to carry it as a 9mm, to make it 100%reliable, I already have Glock 19 mags

Extractor I assume, what else



Thanks

I was told by a Glock armorer at the last Oaks show that nothing else is needed to convert a G23 to a 9mm "G19" except the barrel and new magazine. He said everything else is the same - extractor, recoil spring, etc. He also said the barrel to convert to 9mm is just a standard G19 barrel, nothing special about it.
You do need to use Glock 9mm magazines in place of the G23 40 mags.
In any case, I bought a 9mm Lone Wolf barrel and it works perfectly in a G23.

I have a Glock 27 and have a 40-9 barrel. Basically the same thing but subcompact. Just swap the barrel and use the 9mm mags. Very simple. I've never had a problem with mine. I use it as a 9mm more than a 40sw. Once I get a dedicated 40sw then my G27 will always be a 9mm

I have had no problems with mine with G17 or G19 magazines. I would carry it with those without worrying about the extractor.

I did have some issues with a G18 magazine. It seems to only reliably work with WWB ammo.

If I were you I would try it with a wide variety ammo and see if had hiccups with any particular brand or load. Then carry it with the ammo that it works perfectly with.

I would have GUESSED that the barrels are different because of the OD of the barrel. I know you can fit a .40 barrel in a 9mm slide, so how is it that a factory 9mm barrel will fit in a .40 slide without there being excess clearance around the barrel?

I was under the impression that 9mm "conversion" barrels have the OD of a .40 bbl and ID of a 9mm bbl

I've not seen a .40 barrel go in a 9mm slide, but the 9mm barrels in the .40 slides are heavy walled/bull barrels (sort of) so they fit the same diameter.

That's what I would have guessed also. But the armorer was emphatic that the Lone Wolf 9mm barrel was not a "conversion" - just a standard 9mm barrel. He said it would work perfectly in the .40 Glock and would not need to have the extractor or recoil spring replaced and he was apparently correct. I have not had any problems so far.

I did not ask, and he did not say, if the reverse is true - if a .40 barrel would work in a 9mm Glock. I don't know if it will or not? Anyone try it?
