Chris, I tend to disagree with you on the handle matter
If we want to have the "perfect" gun, or at least as close to perfect as possible, we shouldn't just put any handle that fits eveyone's hand...
The handle is probably one of the most important pieces in a gun and the precision depends very much on it. Bad angle, bad position, insufficient support are a sure recipe for bad recoil that will seriously impact the precision of the gun. And after all the effort to make enclosed track and make sure the gun will shoot as straight as possible, putting the wrong handle will mess it all up...
That's my 2 cents.
