Sss - sharp shooter supply I believe. Ive seen a couple places where they are highly recommended. Can tune them down to a very low trigger pull.

However, I went to their website and found that the trigger they offer is discontinued?

And this will be going into a hunting rifle. So stock 3 screw will likely work for me unless upgrading the trigger is close to the same price.
