There are a few things that could be causing your trigger to feel “heavy”. It’s possible that the bolt is not seating all the way forward into the battery, which would put extra tension on the trigger. You can try gently tapping the butt of the rifle on a solid surface to ensure that the bolt is fully seated.
It’s also possible that you have too much gun oil or grease on your firing pin, which can create friction and make it harder for the trigger to move. Try cleaning off as much of the oil or grease as you can, and then see if it feels better. If it doesn’t, you may need to have a gunsmith take a look at it to see if there’s anything else that can be done.
