I would expect it to be about the same as my 686-8, which was ~12 lbs DA, and ~5 lbs SA.
Dry firing like a maniac for a couple weeks knocked off a half lb.
I recommend pulling side plates to check for oil on new S&Ws. Some ship fairly dry, or oil could've seeped out if it sat for a long time before sale. Just use appropriate driver bits and be careful not to scratch that finish.
FYI, if you use a Wolff Power Rib mainspring, even the 'carry' weight one will require a longer strain screw in modern S&W revolvers for reliable DA ignition, especially with harder primers. I also don't like lighter than 15 lb rebound springs; reset feels mushy to me.
