Model 617-6, original owner, fired less than 1000 rounds. This is the 4" 10-shot model, and it does contain the S&W lock. Price reduced to $575. Contains original box and all paperwork including blank registration card. Beautiful gun, I just don't use it. I'd prefer a straight sale but would consider trading for a Glock 26 Gen 4 with low round count in excellent condition, plus some cash. I'm a Tri-County member so am available to meet there as one option. Oregon State driver's license or (preferably) CHL required as proof of identity for transaction. Also available as an extra: several DS 10 speed loaders and loading block.
