Geez. This bodes well for the QC even after the fact. You send in a broken, blown up gun, and the repair crew doesn't notice the slide, just because you didn't mention it? Not exactly the attention to detail you should see in a repair technician. You'd think they'd at least have contacted you and asked if you wanted the cracked slide addressed before sending it back.
No offense, but I hope I have a better tech working on my P380 that's been there for a couple weeks.
