The slide you have to push down before pushing forward, not sure why. Or pull the trigger, but I've found that's not necessary. I can't really tell from the pics but I don't see anything I woudl be concerned about, but to be safe I would the photos to HK. I don't know if this forum is checked by the actual hk cs team or not? I am surprised no one else responded. Maybe repost in the handgun or range report section..good luck!
