Kimber 9mm mags04/03/2017 ByWilliam Watson I received four SS Kimber mags, they would not seat in my new 9mm Kimber Stainless II. Upon investigation they were stopping at the mag release, the mags have a slight indentation that works as a lead in to the release, there was a burr at the indentation. I benched the burr and created a small radius with a toolmakers file and the mags worked perfectly. Just a small thing but a pain for the cost.
