I had a Tri-Glide trigger system in my SV. A couple of months back when I had to install a new fire control system in my gun, I went with a trigger bow without the tri-glide ball, but stuck with SV hammer, disconnector and Tri-glide sear spring. Both trigger jobs were done by the same gunsmith, and I haven't notice any difference in the "feel" of the trigger pull between the 2.
