I have two spare red-blade target triggers taken off precision target actions (PTA). While on the PTA I could adjust the pull weight down to about 8 ounces and maintain reliability. However, when I put one of the precision triggers on a standard Model 10 (with Accu-trigger) it won’t adjust below 1.5 pounds. The spring is fully bottomed out against the lever arm and the tiny protrusion at the top of the spring is in the proper hole in the frame.
Any thoughts on why it doesn’t have the same adjustment range as it would on the precision action?
