I have a Glock20 and I presume it can be converted to shoot also .45acp. Would you please let me know what changes are necessary. A barrel of course and mags. What else?

Nope, a simple barrel swap is not possible. The breach face of the G20 is much smaller than a G21.
The only way to complete this conversion is to pick up a complete top end. No worries, we have lots of them. Stock length, tactical and six inch. See them here: http://www.lonewolfdist.com/Search.a...RM=lwd-slide21

Thanks for information. But I'm not an USA resident so I'll probably have to contact one of your EU distributors. Which one would you recommend?
