I called KKM and spoke to a gentleman and purchased a standard length G20 barrel. KKM has a good reputation for both improved accuracy and chamber support, both important to me, an accuracy minded hand-loader. I could not have had a better interaction with any company...the guy was a well-informed & great representative for his company. Next week the barrel should show up then I'll have to try it out. In the mean time I must say that KKM is a great place to work with. MyTime Wanna kill these ads? We can help!
