My friend just traded for this older 44 mag blackhawk, 3 screw, 4 number serial number. Hoping to get some help on the value. Has Micro rear sight and a red ramp front sight. Locks up tight and shoots great. The trigger pull feels like less that a pound. The grip frame is shiney, aluminum, stainless steel or nickel plated. Not sure. Rest of the gun is blue. The barrel is 6 1/2 inches long. Does not have the transfer bar.
