Can you get a dropin barrel for a Glock 20 to convert from 10mm to .40S&W?

Short answer is yes.. Does anyone make one I don't know.. I know you can get one made.. Bar-sto will do just about anything...
 
Glock Barrel

If that one doesn't work out, look at Glockmeister.com . I ordered a KKM stainless barrel in December, had it in 2 weeks, cost about $220 total. I am totally happy with this purchase, put 200 .40 through my G 20 today in the sunshine:)
 
okay so i confess

have fired .40S&W straight out of my GLOCK 20. Magazines and Barrel functioned without problem....usually i do this for a few rounds as part of my whole 10mm is a longer .40S&W speach.
 
I also have a KKM .40 for my Glock20, but the ejected rounds come straight back at my face. Looks like some kind if ejector/extractor modification is needed.
 
I've got a KKM .45--->10mm conversion barrel for my G21. I purchased it from Glockmeister and it arrived in about 4 days.

I had some FTE problems at first, and ordered a second extractor to play with. After filing off a little bit of material it performs perfectly with both calibres.
