There is a thread around here that shows how to tune a 2 or three screw trigger. If you have a 2 screw you can drill and tap the hole for a three screw. It isn't easy but can be done with a home drill press. Does make it easier for very fine adjustments. If you happy with the trigger as a two screw then don't worry about it. Definitely do your research and pay attention to what your doing. Again this isn't a easy mod as the trigger is quit hard to drill and tap. Occasionly you will see a three screw on ebay in a pile of parts you can pick up pretty cheap. My older Savages all have three screws on them and I like them a lot better than the accutrigger models. So well in fact I'm not going to pay $100 to improve them. I will get around to replacing the accutrigger though.

Good luck....Floyd
