The Savage Accu-Trigger is every bit as good as Savage brags it up to be. My 10ML-II has the Accu-Trigger, and it's a good one.

You said that "pump is the only thing I can work well with my bad shoulder," but have you considered going with a semi-auto? I'd think that a Browning BAR ShortTrac .243 would be a perfect addition, and much faster/easier to operate than even a pump gun. Of course, the price is a bit more, but you get a lot of gun for the money with the BAR.
