I recently acquired a 4 in h 29-2 in 44 mag. SN starts with an N143. It is pinned and recessed. However someone says it has been modified because the trigger and hammer are not color case hardened. There is the slightest turn ring on the cylinder and the faintest ring around each cylinder. They also say that the pistol has been buffed and polished to look like new. Any hep you folks could share with me would be awesome.
