i originally posted it under general gunsmithing, george huening. ive know him for a while and since ive been shooting again i knew he was planning on doing some new parts and other work. he told me about this roller ball trigger he was having made a couple of months ago so i ordered one. its really pretty nice. it has the roller in it instead of just flat metal on metal and since its stainless i dont think longevity will be an issue and its comes as a unit, with the roller part, the shaft, and the spring. gh2custom.com is the site, kinda bare bones but his contact info is there.
