There have been a whole bunch of posts on the Ruger trigger in the past..... I tried looking, but all I got was, "Sorry, you can not use the search feature at this time."
Maybe you'll have better luck. If I'm not mistaken, it's called the BX Trigger or something like that.
If memory serves, they were not too bad, but they also weren't very consistent. The packaging allowed you to try it.
Personally, I have a Hornet trigger in my target gun - had it for years before Ruger came out with theirs, and very satisfied with it.
