I don't know if an aftermarket trigger is available. One of the most difficult triggers I've ever worked on and a real shame to put such a POS on such a fine turkey gun. Other than polishing all the contact points, you can only bend the coil spring to release some of the tension which necessitates a difficult reassembly after every tweak. When everything is done, you end up w/ a trigger similar to that on some AR's, w/ a soft take-up before the final firm trigger break. I've been able to get several of the triggers to a clean 4 1/2 - 5 lb release after the soft take-up, but I wouldn't undertake another.
