Looking for a Colt serial number date?
Start with the Colt lookup app, then use the individual model pages to confirm frame type, caliber, barrel marking, sight configuration, finish, stocks, and production era. A serial number points you in the right direction, but the revolver itself confirms the story.

How to Use This Hub
Start with the model name if you already know it. If you only have a serial number, use the Colt lookup app first, then return to the matching model guide to confirm the physical features. Colt serial numbers can overlap across different families, so the best identification comes from combining the serial range with frame size, caliber, barrel markings, ejector rod style, grip pattern, sight type, and finish.
For collector work, do not rely on the number alone. A refinished revolver, changed barrel, replacement stocks, or altered sight configuration can affect both identification and value. The linked pages are meant to narrow the model and era before comparing condition and originality.

Frame Families
Important Colt Revolver Families
Colt revolvers are often best understood by frame size and intended use. The Python and earlier .357 models appeal strongly to premium revolver collectors. The Detective Special and Cobra belong to the compact carry tradition. The Police Positive and Official Police lines represent decades of service revolver history. Trooper and Lawman models bridge classic Colt craftsmanship with later production-era utility.
