What am I doing wrong? I got the grip screw issue resolved and took her out for a test drive. After about 24 rounds down range I noticed that I could see daylight (yes, the sun was actually visible here.) where I shouldn't have daylight. the blue dot is what apparently ejected itself. The manual say's it's the slide stop plunger retaining pin. What does this do? .... I get that it retains the slide stop plunger... I just don't really see it's purpose. I'm hoping that someone can explain the reason why that piece would fail so catastrophically. I was firing reloads, 4.7grn of power pistol, 95grn sierra fmj, new magtech brass. Am I loading too hot for my pistol?
