I was watching the thread about the Glock 20 and need to find out about fitting a 40 SW barrel in it.
Is it drop in?
Do you use the 10mm mags?
Anythiing else I need to know?

Some of the barrels are drop in and some need to be fit I have never had a feeding problem with 40cal in the 10mm mags in myine.

I use both 40 cal and 6" 10mm from Lone Wolf in mine. Both are perfect drop ins. No mag change.

Drop ins, and you can use the same mags and extractor.

I got my .40S&W barrel for my G20SF from KKM Precision and it was a drop-in.
I couldn't be happier. I have now run over 350 rounds thru it using the original mags and not a single malfunction.
