Don't need a reference. As stated it was an opinion. As to your first two questions I never said anyone had. The point is whether its reloaded ammo or a fundamentally modified gun you are needlessly exposing yourself to product liability and to potential evidence that could sway a juries opinion. If you shoot someone your gun will be analyzed in a lab and the trigger pull will be measured. If I have to shoot someone and go to criminal and/or civil court I want the evidence in my favor. For my carry gun I will let any product liability remain in the hands of S&W and Winchester.
