I absolutely love my G20SF and the longer KKM barrel allows me to shoot pretty much anything that I want to put through it. My question is - is the sight radius advantage of a Lonewolf Longslide worth the money to change over to? I thought that if it was "all that". I would sell my stock G20SF and take my KKM barrel, Brass Stacker guide rod and 22# spring. Package them up and send them to LW to let them build and test-fire a complete long slide which I would then use atop my G21SF. Good idea?
