Smith And Wesson Serial Numbers N Frame Jun 2026

Starting in 1980, S&W abandoned six-digit numbers for three letters followed by four digits. This is critical for identifying modern N-frames.

N-prefix guns are very common but desirable. The pinned barrel and recessed chambers (P&R) were phased out in 1982 (Model 29-3, 27-3, etc.). Most N-prefix guns below N900,000 are P&R; above that may be non-P&R.

Early N-frames (beginning with the .44 Hand Ejector "New Century" in 1908) used numerical sequences that often overlapped with other frame sizes. en.wikipedia.org Post-War "S" Prefix: Following WWII, S&W began using an "

Serial numbers in this era usually follow an "N" followed by six digits (e.g., N2142xx). 3. Modern Triple-Alpha System (1980s–Present) smith and wesson serial numbers n frame

To get an exact year (not just a range), you need the (4th Edition) by Supica and Nahas. However, here is a condensed cheat sheet for popular N-frames:

Smith & Wesson serial numbers are a unique identifier assigned to each firearm produced by the company. These numbers are used to track production, monitor inventory, and verify authenticity. Serial numbers typically consist of a combination of letters and numbers, which provide valuable information about the firearm, including its model, production date, and manufacturing facility.

For N-frames, a dash 2 is the most desirable for pre-1982 collectors. A dash 5 or higher indicates modern metallurgy but fewer handmade touches. Starting in 1980, S&W abandoned six-digit numbers for

: Shared chronological ranges. The first N-frame was the .44 Hand Ejector 1st Model (Triple Lock) introduced in 1907. 2. The "S" Serial Era (1946 – 1969)

In 1983, S&W switched to a system of three letters followed by four digits. These are much harder to date precisely without a factory letter.

In 1969–1970, S&W ran out of S-prefix numbers and switched to . This marks the late classic and early modern N-frame period. The pinned barrel and recessed chambers (P&R) were

For any three-letter prefix N-frame made after 1983, a factory letter (from S&W Historical Foundation) is the only sure way to get month/year.

Understanding Smith & Wesson serial numbers on the N-frame is the key to unlocking a gun's manufacturing date, engineering changes (dash numbers), and historical context. This guide provides a deep dive into the chronology, location, and nuances of N-frame serial numbers.

After WWII, S&W used an prefix on all N-frames. This indicated the new hammer block safety. The S prefix is the most common marking on classic post-war N-frames.
