To tell how old a Smith & Wesson Model 15 revolver is, start with the serial number on the gun, not the model name alone. For S&W revolvers, the serial is usually on the bottom of the grip frame and may also appear on the butt or under the grips; if you’re seeing a number on the yoke/crane area, that may be an assembly number instead of the serial number.

What to check

  • Remove the grips carefully and look at the grip frame for the serial number.
  • Note any prefix letters before the number, because those often help place the gun in a production range.
  • Check the barrel and frame markings for the exact model designation; the Model 15 name was not used on early guns, so older examples may be marked differently.

Best way to date it

The most reliable method is to match the serial number to Smith & Wesson reference tables or ask Smith & Wesson / the Smith & Wesson Historical Foundation for a factory letter or date estimate. Community forums also help, but official records are better when you need a firm answer.

Quick example

If the gun has a serial prefix and the grips are off, that prefix can place it in a broad era; without the serial number, you can usually only narrow it down by features like screw count, sight style, and barrel markings.

Important caution

Avoid assuming the gun’s age from the model number alone, because Model 15 revolvers were made over many years and small design changes can indicate different production periods.

If you want a precise estimate, send the serial number exactly as stamped, plus clear photos of the barrel, frame, and grip area.
