FWIW, I've been shooting, buying & selling S&W revolvers since the early 1960's, and can say that the only bent cranes I've ever come across were the result of holding the gun by the grip only and opening and/or closing a loaded cylinder fast with a flip of the holding wrist.
If you didn't do that, I suggest you send the gun directly back to S&W, instead of to a gunsmith, seller or not.
I just hope that some fool didn't play with that gun at the seller's venue, before you ever saw/bought it, causing S&W to void the warranty.
