Taurus repair status page says my revolver headed back to me... 
Wonder if they will send my snap caps back to me. Wonder what caused the dang thing to lock up so totally. Hope they send me a note.
From what others say - you will likely get no info. Just a note that says "repaired." If they changed parts, they MIGHT mention the biggest part they changed (but usually not a list of everything)... at least that's what I have seen others say when they get their Taurus back from repair...
I've actually seen people say they have sent the same gun in 3-4 times, and sometimes get it back 1x with NOTHING done to it all.
