Thanks for the info. I didn't realize they could be taken down to 2-3lbs, I figured if I was lucky they could get it to 4.5-5lbs.
That also depends on who does the work.
I did mine including the trigger stop. It worked out well.
But, I’ve done a few, felt comfortable tackling this project.
Unless one has confidence, I’d say find a professional to do the work.
Triggers aren’t something to be messing with.
