If they are like the Sacramento P.D. Commemoratives they are standard off the line guns that are engraved the S.P.D. guns were all 1 of 200 in both 4 & 6 inch.I got 2 of each and gave them to my Sons and kept a 4 & 6 for myself in 1984 they were $400.00 each and they are shooting guns for me I have no queens in my safe. The only thing I had done was a Combat Tune by Bill Davis Co.
