I have been able to safely reduce trigger pull weight on original Savage 110 rifles down to 4 LB pull. Several will safely adjust to 3LB pull but be very cautious when going to this light weight pull. When properly adjusted, the savage trigger provides a very dependable and crisp hunting trigger.
If looking for a lighter pull weight on Savage 110 rifle, you need go to aftermarket . Not to hard to install but will cost over $100.
