It's only my opinion, but I would value an SD9 at least $150.00 more than a model 10. 10's are common as dirt, & a snub 10 never made any sense to me. But I wouldn't pay $75.00 for a new mod 10 when they sold new for that, I ponied up a little more & bought the much nicer model 15 in a 4" barrel, or looked a little harder to find a Chief's Spl if I wanted a snub.
