If I'd have to buy something like the KKM barrel to shoot hot 10mm, seems like I'd be better off converting a G21 and having both calibers as an option...
Back in the day before I bought my G20 frame ( green ) ,that is exactly what I did … however , I purchased an entire factory Glock upper with matched factory barrel and slide , not just the barrel & magazine . Bought the Barsto's after the fact … I do like the factory Glock barrels with moderate plated / jacketed loads .
