A friend gave me a Win. Model 100, 308, Semi Auto. Great looking gun, shoots well.It is a right hand safety and i would like to switch it to a left hand safety. I don't mind the brass shooting by me, my concentration is good and glasses keep it safe. It is a pain going for the safety and fumbling with it. How hard is it to switch it to left hand. or am i stuck with hand to hand combat with it in the field. Thanks,
