I agree that slow important. When I am working a trigger I'll reassemble and test as many times as necessary to get the desired result but 2-3 is the norm for the Rugers.
Went a different way on one of my ARs. After being cautioned not to even attempt to work on it by knowledgeable shooters here at the fire, I proceeded under the assumption that the worst I could do is further screw up a trigger that truly sucked to begin with.
And further screw it up I did. Got a little aggressive and what I ended up with, because I didn't fully understand the geometry, was a rifle that would fire when the trigger was pulled and again when it was released. It was much smoother, lighter and crisper, though.
Ended up replacing that trigger - a happy ending as far as I'm concerned.
