The official serial number for all Smith & Wesson revolvers is stamped on the . While numbers may appear on the barrel, cylinder, or inside the yoke, these are often assembly numbers used for factory fitting and do not indicate the manufacturing date. Smith & Wesson Serial Numbers
Before we dive into serial numbers, let’s clarify the anatomy. The "screw count" refers to the visible screws holding the revolver together, primarily on the sideplate and frame.
A mismatched serial number (e.g., a frame from 1948 with a cylinder from 1952) can cut a gun’s collector value by 50% or more. Conversely, a pristine 5-screw with a correct, verifiable serial number can be worth thousands. smith and wesson 5 screw serial numbers
In 1957, S&W eliminated the uppermost sideplate screw (the one at the top rear of the sideplate). This created the configuration. However, the frames were already stamped, so you will find "transition" guns.
In the world of S&W collecting, the fifth screw might be small, but the history it represents is immense. The official serial number for all Smith &
For revolver enthusiasts and collectors, few phrases evoke the golden age of American firearm manufacturing like Before the age of CNC machines, drop-safe redesigns, and cost-cutting measures, Smith & Wesson built their revolvers with a distinct five-screw sideplate configuration. These guns, produced primarily from the late 19th century until the late 1950s, represent the pinnacle of hand-fitted craftsmanship.
Because 5-screw S&Ws are valuable, fakes exist. The serial number will expose a "fake" 5-screw immediately. The "screw count" refers to the visible screws
This is the most common 5-screw revolver. Millions were made. Serial numbers are typically found on the butt.
Serial numbers for 5-screw models are most often found on the . While specific ranges vary by model (K-frame, N-frame, etc.), these general periods cover the transition out of the 5-screw era: Pre-1955 : Most standard revolvers featured five screws.
Some 4-screw guns from 1957-1958 still have serial numbers that overlap with late 5-screw ranges. The only way to verify is physical inspection. If your gun has a serial number indicating 1957 but lacks the cylinder stop screw on the front strap, it is a 4-screw.
If you own a Smith & Wesson revolver with five screws visible on the frame, you have a classic example of the company’s pre-1957 engineering. The "5-screw" designation refers to the sideplate and cylinder stop screw configuration, and the serial number is key to identifying its production era.
