Was curious as others have metioned if extended barrel either 5 or 6" is worth it in the g20, the factory barrel is 4.6" - so the 5" wuld only be .40" longer and the 6" 1.4" longer is there really that much speed and energy retained, with these? I was also thinking about getting a KKM .40 conversion barrel for the g20 was curious if KKM's stuff have fully suppoerted chambers like jarvis barrels?

The difference between 4.6" and 6" velocities seems to average about 80fps. with 180gr. bullets.
