I heard of firing pin problems and feeding problems back 25 plus years ago when I first purchased my Reising M50. Recently I took my M50 out of the closet and noticed I had two extra new firing pins and a new set of springs that I purchased along with three 30 rd. mags way back when. After disassembly, I noticed the original firing pin was slightly bent. I completed the above firing pin mod, as it seemed so logical. I'm now eager to go out and shoot a gun I haven't fired in a long long time. Thanks again. I just wish I had read this years ago.
