I was a stupid idiot who didn't know any better until recently about now dropping the slide on on an empty chamber. When inspecting the sear with my naked eye, I can see a little ridge on the hammer and a small one on the sear. It looked kind of like it was being banged hard which is actually what happened. I'm probably being too anal, cause I haven't had any problems yet. But compared to the other hammer and sear, the "bad" one had some worn ridges on it. The others were smooth and crisp.
