Depending on the model you might go and look into a *Rifle Basix trigger. If they have one for your model and the 22 cal bolt gun? They are nice triggers not expensive and easy to install! Or call Marlin Tech Support. I know a few years ago after giving them a tough time at the shot show over their little Model 917 17 HMR Trigger. They advised they were going to have a new and nicer trigger out for the 917. So it is possible they might have some insight on one to fit your model rifle.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
-- John F. Kennedy
