The six-shot Colt Detective Special was the standard issue sidearm of Crime Wing inside Hong Kong Police Force, only to be replaced by SIG Sauer P250 after multiple years of use. The Colt Detective Special was the first revolver issued to French customs agents, meant to replace the old Browning 10/22 and MAB D pistols.

Colt 1917 Revolver Serial Numbers

  • The.38 S&W and.38 Colt New Police rounds were quite stubby (about 1⅛ inches overall length), so they were a perfect fit in the short cylinders of the compact, small-framed Colt Police Positive and S&W’s Regulation Police revolver, though because of the S&W’s tiny cylinder, it could only hold five rounds to Colt’s six.
  • Note, in the mid 1960's Colt started to add letters to the serial number. The 60's Cobra and Agent should have the letters 'LW' on the end of the serial number, but many did not.: Thank you so much the serial # is 262XX LW so im assuming 60's model.
