The simplest fix is to simply install the WWG Happy trigger. Midway sells them for around $80-$90. Definitely on the expensive side, but, IMO, well worth it and you can swap them out yourself. It will leave you with about a 3 lb crisp trigger pull. If you live near a good gunsmith, he should be able to do a trigger job for about half that. I don't know how many rounds you have through your rifle, but another way to smooth out the trigger is to run about 3,000 rounds through it. Time and use does wonders to Marlin triggers.
