I just shot 100 rounds thru my shadow 2 kadet with no malfunction. I have a question for you, when cleaning the barrel, do you just tilt it to clean while leaving in the slide. That seemed to work good doing it that way. I could not see another way to do it without removing the plastic piece in front of the slide. User manual instructions did not say much about it? Heard spare mags are expensive. PO9 has same sights I think?
