Questor - yes I do. I have found the Chip McCormick trigger group parts require the least amount of fitting (actually, just beveling the edges on the trigger bar for smoother travel and filing/grinding off a bit of the plastic off the top/bottom of those triggers get them fitted nicely. They also carry a trigger adjustment screw and have worked very well for me. One other aspect of the plastic triggers by McCormick that I like is the ease of which I can contour the face of the trigger to my particular tastes. All in all I feel the Chip McCormick trigger, or hammer and trigger groups parts are pretty inexpensive and pretty easy to work with. HTH. Mikey.
