please be extremely careful
many triggers and sears are made from scintered metal...this means a very hard outer 1-3 thousandths of an inch and very porous internal crystalline structure.
You would be better off getting a new savage with the accu-trigger system or buying replacement parts from a reputable aftermarket company that you know are made from machined steel instead of scintered castings.
Here is the rub...if you break through the scintered surface the least little bit, it will continue to degrade over time and become more "sticky" than when you started...I learned my lesson on this subject the hard way...Granddad was a gunsmith and taught me well...but he also let me make a few mistakes along the way as a learning tool...provided the goofs were on my equipment and not his or a customers.
