I just purchased a used Model 60 at an auction. It was advertised as a 'Pro' model. How do I tell if that's correct?

The serial number is DAT4527. What is the year of manufacture?


The grips are Uncle Mike's (came on the gun). I've put 100 rounds of Winchester 125 gr FMJ .38 Special and 50 rounds of Winchester 110 gr JHP .357 magnums through it so far.

I used the first two cylinders of .38 Special to adjust the sights for a center hold 21 foot target, then shot for groups, getting to 2 1/2 inches, two hand hold. I then shot two cylinders of .357's for groups but essentially got a foot long vertical string on center.

The grips made the .357's tolerable, but I'm going to try some Winchester 125 gr JHP .38 Special +P's to see if the vertical string can be eliminated. I think I can get to acceptable accuracy with the .357's if I can tolerate them to practice. So far, the grips appear to make that possible. We'll see. If not, the +P's should work ok.
