I've been playing with my Witness Long Slide over the past week or two, trying to improve the DA trigger.
It had always been kind of heavy toward the rear of the trigger pull range, "stacking" or so it seemed.
I've been progressively taking more and more metal off the side and rear of the trigger bar. It became clear, as I examined the gun, that the trigger bar was just too wide and long for the best trigger pull.
I guess the trigger bar was simply pushing against the frame -- and that might have been why it broke in the first place: internal tension causing a fracture.
After many sessions of filing, sanding and polishing, the double-action pull is now approaching the smoothness and lightness of my 85 Combat and Pre-B 75. (And believe me: there's still PLENTY of metal there...)
I'm amazed. I did NOT expect this dramatic result when I started.
