Since it appears your M1doesn't have any real collector value and is going to be used to shoot at competitions, why not dress her up? There are services out there that will reparkerize it and perform a trigger job so everything will look uniform and your trigger will perform better in your competitions. Drop it in a nice new stock and you will have a real beauty that performs as good as it looks. I have never used this service, but for about $200 plus S&H, you can get the trigger job and reparkerizing done. Maybe someone else here can recommend a good place to have those services done also. Good luck!
