The nickel plating provides superior corrosion resistance compared to blued steel magazines, extending operational life in humid conditions. Heat-treated carbon steel construction maintains dimensional stability under repeated loading cycles, while the anti-tilt follower design prevents nose-diving malfunctions common with worn factory magazines.
