My issue with the Ruger trigger is the two click reset. So far, this actually has not been a problem under live fire conditions, just dry fire. So it could be a non-issue itself, but since no one seems to be talking about it I thought I would mention it. Here is a video to show what I am talking about.
For someone who has put a lot of trigger time in behind a Glock where it is generally taught to use the trigger reset, this causes havoc. For other people used to shooting other types of guns with less defined trigger resets, maybe not so much.
