Unless you can find someone to replace the drum on the pinion, you will have to buy the pinion w/drum. I assume you have tried tightening the windage screw.
Almost every M-1 I have needs to have the windage screw tightened up from time to time. You should ALWAYS do this before a match. If you can adjust the sight without too much effort, and cannot depress the sight by putting your thumb on the aperture and pressing down with say 5-10 lbs. force, you are good to go. If it will not hold you will have to follow Devil Dog's advice.
