What it sounds like that you have is a Model 1640 action
. These were the first Generation seriers of Husqvarna actions marketed by S&W. I have an A-Model 1640 action shown below with the non adjustable trigger. Later on, The Engineer's of Husqvarna revised the 1640 action and called the new revision the Model 1900 action. That one has the adjustable trigger and smooth bolt control feed and a bolt face that completly surrounds the cartridge case. If you have the older 1640 action, there is hope for your stiff trigger.
This company supplies a bolt in trigger that is of Match grade quality for less than $100.00, see the link I have provided. Also, I provided a link to a Husqvarna rifle site that tells much on these rifles, I hope it helps, Hammerdown
