Ruger will never worry about improving the trigger pull on the 10/22. Give it up. Lawyers and good sales with the existing triggers being the main causes. If people would stop buying them then Ruger may change things but that ain't gonna happen and I could care less if they did. Why? Because they will never be, even with an honest attempt at improving, as good as you can get with a cheap aftermarket hammer.
If you believe Ruger might change things then Santa is a very real possibility for ya too.
