This specific designation refers to a .32 caliber revolver, typically a variation of the Smith & Wesson Model 34, known for its compact size and six-shot capacity. These handguns were often chambered in .32 Smith & Wesson Long cartridges and marketed toward law enforcement and civilians seeking a reliable and concealable firearm for personal protection.
Compact revolvers in .32 caliber gained popularity in the early to mid-20th century due to their balance of manageable recoil, adequate stopping power, and ease of concealment. Their relatively simple operation and maintenance also contributed to their widespread adoption. Such firearms played a significant role in the history of personal defense and law enforcement armament, representing a transition towards more compact and readily available handguns.
