I picked up a chief's special tonight with a low 300XX serial number. Can someone please tell me when this gun was made. Thank you. It has a flat latch and serrated front ramp. Everything is matching on it and it is in very good shape. I kinda bought it on the spur of the moment not really knowing much about it except it was probably relatively old with the serial number. The gun is in very good shape other than a little blueing wear on the cylinder and one grip has a slight nick in it. I got it for $195. How did I do?
