So I recently purchased a savage axis in .350 legend for whitetail hunting in the lower half of Michigan. For the money it puts down deer and is a blast to shoot. My only gripe is the trigger pull is painfully stiff. I found the MCarbo trigger kit and purchased it only to find out it won’t work with my style of trigger due to the spring retainer hole not being threaded. After looking for a solution online I put a few ideas I saw together and did some brainstorming and found a solution I think is pretty good! I bought a 5/32 x 3/4” roll pin and hammered it into the hole. It fits real snug (definitely not coming loose) and is almost the perfect length! I trimmed mine down about 1/16” after getting it hammered flush with the bottom of the hole just to be safe, but I’m sure you could just hammer it farther instead of trimming.I have to say I’m pretty happy with the outcome!
