Go with the KKM, I have used 3 of them and use a 40 cal match barrel in my G-20. Have been very pleased with the results.
jim..,
The G20 is a 10mm, right? Can you put a 40S&W barrel on it and get it to run? How about .357SIG?
Reason I ask is, I've been thinking about the 10mm but would also like to shoot the cheaper 40S&W - if it will work.
