Glock 20 conversion barrels

[envonge]

Hello,

I am considering 2 conversion barrels for my Glock 20 (.40 S&W, .357 sig) and was wondering what all is required.

Do I just need the conversion barrel designed specifically for the Glock 20 or something more?

Thanks

That's all you need (the conversion barrels). I have a Federal Arms G20 .357SIG stock length conversion barrel and used to have (sold it off once I got my G35) a KKM G20 .40S&W stock length conversion barrel for my G20 and they both work/worked great with the stock recoil rod spring weight (have a Glockmeister SS captured guide rod assembly for it) and the G20 mags.
