Three mags came with the Luger I got this week. One has a silver finish (I assume it is nickel-plated), the other two are blued. The first has a wooden bottom that is damaged on one side and bears the number 3447. The other two have pristine wooden bottoms without any markings.The silver-colored mag will take eight rounds. The other two appear to be designed to accept only seven rounds but they are extremely difficult to load. I assume that the blued mags are probably of recent production, while the nickel one is original German. Any comments on seven versus eight round mags and related issues?
