Hi i just got a marlin bolt action 917v in .17HMR. But the trigger is too heavey for my taste. I want to lighten it up a bit. Any instructions on how? I already zeroed it so if removeing the stock is required would i lose my zero?

Not familiar with that model Marlin, but a slight zero shift is likely when removing it from the stock. If you go to a good auto store, you can get a sheet of 1500 grit polishing paper, and just smooth up the notches that release the striker. You can find the spots you need to polish by watching the trigger operation with the stock removed(and no ammo, of course!). If you stick with the 1500 grit, you can't take off more than one thousandth of metal, so you wont ruin anything. A dab of moly grease on the trigger pins, and sear notch also helps a lot.

Just a suggestion. It has been my experience that trigger-pull weight is often used as a substitute for obtaining a nice crisp trigger release. In other words, the objectional “feel†isn’t the weight of the pull as much as it is the smoothness and crispness of pull and let off. Just reducing the weight doesn’t cure the problem, and it is way too easy to keep going lighter and lighter trying to get that “feel“ only to end up with an unsafe weight of pull...that still feels like crap.

If you're not familiar with firearm triggers and how they work, then you should seek the services of a professional gunsmith who is experienced with tuning these particular triggers.

Unlike other triggers where you might get away with turning a screw or two to improve the pull, these particular triggers require sear angle changes to make them right. Depending on how much change you have to make, you may need to rebuild the safety system for it to work properly afterwards. Save yourself some headaches and potential legal problems and hire this done.

Rifle Basix sells a drop in trigger, check Midway
