I tend to agree with Tony Wall, a favorite tuner of the Verminhunterstv Youtube channel. A kit is part of a tune. A good tune by one of the top guys is basically blueprinting the gun. Every internal surface is addressed, receiver tube is honed and polished, trigger is normally smoothed, etc. I am sure the V-glide kit is a wonderful product, but not necessarily a replacement for a good tune. Kind of like a brand new engine in a car with a so-so transmition and slightly worn tires.
