I want to ask a question. My 1955 99 F model locks up tight. When I squeeze off a round or dry fire the lever drops slighty after the firing pin moves foward. The lever is up and tight with the firing pin in the cocked position. Is that consider normal? I had a trigger job on this rifle years ago by a very good gunsmith in Michigan who works on 99's. I never consider this a problem since after firing I am ready to cock the lever to eject the spent case. However none of my other 99's do this. They are from the 1920's and 1930's. Also the factory triggers back then were much better that the post war factory triggers which I thought needed adjusting for better pull and reduced creep. Your thoughts.
