There was a thread on this gun awhile back. It’s a 29-3 with a 3” slim barrel that the consensus was that is not original to the gun. Gun has a spot where the finish looks funky on the cylinder and a couple of spots on the right hand side as shown in the pictures. Gun is very accurate, no functional issues at all.
Looking for $700 shipped to your FFL. I’m easy on payment methods.
