Compatibility:
This barrel is from the Smith & Wesson K Frame Military & Police 1st Model, one of the earliest iterations of the legendary M&P revolver series. The 1st Model M&P was produced from 1899-1902 and featured a 4-screw frame design (later models used 5 screws). This barrel is chambered in .38 Colt ctg., which was the original chambering before .38 Special became standard. The pinned barrel design was used in early production and is highly collectible. This is an old style barrel suitable for restoration projects or as a collectible piece.

About the M&P 1st Model:
The Smith & Wesson Military & Police revolver (later designated Model 10) is one of the most iconic and widely produced revolvers in history. The 1st Model, introduced in 1899, was the first swing-out cylinder .38 caliber revolver from S&W and became the foundation for the K Frame series. Early production guns like Serial #3312 are highly collectible and represent an important piece of firearms history.

Condition:
This is a used factory barrel removed from Serial #3312. The barrel shows light pitting consistent with age and use, adding to its historic character. The blue finish shows typical wear from over a century of existence. This is a collectible part suitable for restoration projects or display. The pinned barrel design is a desirable feature among collectors.

Installation:
Professional gunsmith installation is strongly recommended. This is a historic part that requires proper fitting and headspace verification. Given the age and collectible nature of this barrel, it is best suited for restoration projects or as a collectible piece rather than heavy use. Knowledge of early Smith & Wesson revolver mechanisms is essential.
