476 .357 Magnums were shipped to the Kansas City Police Department in 1939/1940. 70 of those guns have surfaced in collections known to this community. Out of those 70 guns only 3 originally surfaced with serial number matching grips, and now this gun makes 4 with matching grips. Most of the KCPD guns went through multiple refinishing cycles. Most were refinished by the KCPD armorer, who apparently paid little attention to grip serial numbers, and many others were also refinished at the factory where new non-serialized grips were often installed. So finding a Pre-war KCPD .357 Magnum with serial number matching grips is the exception.
