Glock 20 9mm conversion?

[Leadingall]

I see lone wolf is selling 9mm conversion barrels for the G20. I'm curious though, how would the magazine work? Clearly the G17 mags are too narrow, are you supposed to load up a 10mm mag with 9's and expect it to function with any sort of reliability? I get that you'd have to switch out recoil springs and likely extractors, but how to feed ammo has got me stumped. Has anyone run this set up? Or has anyone had experience with the .40 conversion and what has the reliability been with that set up?

I have only my experience with a Glock 22 conversion to 9mm, using the 40-to-9 barrel from LoneWolf.

It's been nearly flawless, when using Glock 17 magazines, and making no other alterations to other parts (like the ejector or extractor)

It still works pretty well, most of the time, even when loading 9mm rounds into Glock 22 magazines.

I also have the .357sig conversion barrel, and it works flawlessly with Glock 22 magazines. (It should, they are the same mags used for .357sig guns)

I'm interested to know how well this works for you.
