I have a custom .45 rifle with set triggers. I never really liked set triggers anyway, but now mine seems to be malfunctioning. Rear trigger sets OK, but front trigger does not work when pulled. Mainspring seems fine. If you pull the front trigger waaaay back, eventually it will drop the hammer. I have turned the adjustment screw in, out, and everything, doesn't seem to help. I would rather replace the whole thing with a single trigger, BUT I realize the trigger plate is set so far back that a single trigger might not fit in the space, especially since the tang bolt threads into the trigger plate about where the single trigger would need to pivot. Not sure what to do. Set triggers look to be high quality but I am one of those people who can take things apart, but never get them back together again right. Suggestions?
