Prior to 1975 you are not able to determine the date of manufacture by the serial number. Prior to 1992 we have information that, while missing some years, may be helpful to you in determining the age of your gun.
If your gun was manufactured in or after the year 1992 then the first 3 or 4 digits of the serial number will allow you to determine when your gun was manufactured. If the first 3 or 4 digits of your serial number are 1294 or D94, then your gun was made in December of 1994. The charts below will help you determine when your product was manufactured.
