So, I've been putting up with my mosin trigger for some time. Then I bought a Savage MKII with accutrigger and I'm completely spoiled. My 91/30's trigger legitimately feels like a water gun trigger (if there were a marshmellow behind it). Is this normal? I've read about polishing the sear and shortening/shimming a spring to improve it. Has anyone tried this? I'm thinking of finding a guide and giving it a go, as I'm very mechanically inclined (and patient), but I don't want to waste my time if it's still going to feel like a water gun. What about the M39 trigger? Will it fit?
