I was going to shoot my RIA 03 in a M1, Springfield CMP match. When they weighed my trigger I was not able to shoot my rifle because the trigger broke at less than 3.5 lbs. I put in a new sear spring and the trigger still breaks at less than 3.5 lbs. (Around 48 ounces) What would you recommend to increase the trigger pull weight to at least 3.5 lbs? Any advice would be appreciated. Thanks
