Glock 21 to Glock 20?

What would be the best way to do this conversion? New slide and barrel or conversion barrel. If it's slide and barrel I may just buy a G20. Anyone make conversion barrels? Thanks

I have not done the conversion but I did sell me OEM g20 slide assembly and barrel to someone to run on their g21.

I would go with the whole slide assembly, barrel, and mag for a conversion.

Barrel and mag is all and I would get like a 20# spring. Sum mite also buy a extractor for 10mm.

Conversion barrel is what I was talking about lone wolf and sum others make them.

Not being a fan of Glock, I'm not sure how that'll work
The Breach Face on a .45 is over 0.05" larger than that of the 10mm
Unless the Extractor is set-up just right, it'll never cycle
AND, the Recoil Spring on the 45 is way too light for a 10mm
But then again....I may be wrong !

I have a 20 & 21 as well as a 6" L/W barrel for the 20. I have put the 10 mm barrel in the 21 with the 20 mag and had absolutely no problems. 21 was a gen 2. As I was just shooting paper, informally, I did not have any concerns or worries about FTEs but like I said, no problems.
