ive got a Bill Springfield modified trigger as well... sitting in a bag.
it was a nice light setup, and shot fairly well - but ive read over and over about them going south if theyre in a high volume setup. seems that after investigation that he's removing too much of the case/surface hardened engagement surfaces on the sear/trigger when he's stoning *some* of them and thus they now will wear out... and then whoopsie you have a runaway trigger.
just not worth it. especially when the 3rd autocomplete on google is this. yea. yikes.
