A friend of mine called me today because he's having trouble locating GSG-9 22lr mags. His GSG is a pre h&k lawsuit gun. I gave my google foo a try and had no luck finding any mags online for him. I see GSG-5 mags and Promag GSG-5 mags and that's all I can find. I'm unsure if those will work in his rifle or if the h&k mp5 22lr mags will work either. I would like to think since GSG lost the lawsuit it was a complete knock off of the h&k and the h&k mags should fit? Any help would be appreciated.
