OK, I picked up a used Generation 2 19. The guy I got it from was the first owner and he only shot a few hundred rnds thru it. It was pretty cruddy and I gave it a good cleaning. When I stripped it down I noticed that on the right side plastic frame rail (it kinda narrows to a point, its longer than the one on the left) has some light scratches/gouges on it. I was reading that all these do is act as a guide for reinstalling the slide. Is that true? Would this be something I should be concerned with? I may try to get pics posted of it. Also, would CLP hurt the polymer frame? Havn't used it yet but it needs a good hose down.
