If you want to buy a mag check out "cheaper than dirt" thats where i bought my mags for my savage. i just looked and they have the 10rd mags for 13.50 for the mark II and thats a factory savage mag,
i have bought non factory mags for mine and the extra 2-5 bucks is definately worth it. the lips broke off the cheapo mag i bought and now its just a piece of junk laying in my ammo container i guess the spring is still ok and the follower looks decent but that still doesnt make up for the fact i had to buy a real mag that will never need those spare parts.
