I took some pictures of the chamber and I realized they're different. Is this completely fine? If I understand correctly the notches don't really need to be in the exact same place (on the chamber) because they are only responsible for bringing the slide back. RacingManiac also said the SD barrels work in the Nova slides, so that's proof work, but I want to know if there's any effect on the performance / function of the slide.

Edit: It turns out thhe notches on the chamber don't line up with the slide's notches and is incomptible. RM, didn't you say they were supposed to be compatible?
Edit EDIT: WOW, on second look, they gave me the wrong chamber. It does not look the same as the one advertised on the site AND this chamber+barrel was USED. Both the inside and outside areas were scratched and the barrel had DIRT in it inside. I'm extremely displeased with these two pieces and I will be demanding some sort of refund or store credit.
