Inspired by the light strike fix in the FAQ, I did something similar with my Mark II this evening. I hope to get to the range and try it tomorrow. I’ve also had plenty problems with mine.
I simply carefully removed about 1/10 millimeter in the two spots that would stop the firing pin from continuing forward.
the flat top that meets the breech of the barrel, and the front of the protruding part on the side of the firing pin which contacts inside the bolt. So now the theory is the striker part will travel about 1/10 mm further into the rim of the cartridge. We’ll see if it is enough to make a difference or I might take another 1/10 mm. I used my dremel and it went really fast, so be careful not to overdo it.
Of course it might be the cartridge is not properly seated in the chamber, which might cause the case to slide forward when hit by the firing pin and thus cause it to not fire. But I felt I needed to grind something, so now I did that.
I’ll try post a drawing.
