Opinions on the trigger seem to differ wildly. The people who seem to like the trigger seem to be folks (like Bane) who were at special showings, and may have gotten ringers. Guns pulled out of the dealers case seem to not have such good triggers.
One person compared the SR9′s trigger to a Mosin-Nagant revolver, which is not a compliment. The best thing you can say about a lot of Ruger’s triggers is that the guns are popular enough and the triggers bad enough to inspire good aftermarket replacements.
