No lock (sorry kitty), rubber grips, nice shape, although a little leady n the forcing cone, but I think it just needs a good cleaning with a tight brush. Had never seen one of these in 4" before; so for $465 including tax, I put down some earnest money for it, and will return when I get my NJ "purchase chit" for it. Serial CEK62xx, no other goodies, but I am REALLY excited about shooting this one. I have a couple of blued 17's in 6", one from the 50's and another from the late 70's, but this one feels really good in the hand. Feels much like my 586 4" from hefting this one in the shop. Will of course post photos when it's in my hot little hands! Love it!
