How much more accurate are the aftermarket barrels?
I have a G20SF in 10mm. This is my first and only Glock. I have tried half a dozen different factory loads and the accuracy is... how shall I say...less than great.
I'm thinking about putting in a new KKM barrel and see how that goes. What are resonable expectations for an improvement in accuracy?
Also are the KKM drop in barrels really "drop in" ?
