What's the Difference Between .38 and .38 Special?
The terms ".38" and ".38 Special" are often used interchangeably, leading to confusion among firearm enthusiasts and newcomers alike. While seemingly similar, these cartridges possess key distinctions impacting their performance and application. Understanding these differences is crucial for safe and informed handling of firearms.
Caliber vs. Cartridge: A Fundamental Distinction
Before delving into the specifics, it's important to clarify a fundamental concept: caliber refers to the diameter of the bullet, while cartridge encompasses the complete unit—bullet, casing, primer, and propellant. The ".38" designation initially referred to the caliber – approximately 0.38 inches – of a bullet. However, the term has evolved, often being used synonymously with the ".38 Special" cartridge.
The .38 Long Colt: The Precursor
The story begins with the .38 Long Colt cartridge, introduced in the late 19th century. This cartridge, with its relatively long case, provided a significant amount of power for its time. However, its long case presented challenges in revolvers designed for shorter rounds.
The .38 Special: A Standardized Improvement
To address these shortcomings, Smith & Wesson developed the .38 Special in 1898. The .38 Special cartridge retained the same .38 caliber bullet as its predecessor but featured a shorter case, allowing for greater versatility in revolvers. This shorter case was a significant advantage, enabling revolvers to cycle more smoothly and reducing the risk of malfunctions.
Key Differences Summarized:
| Feature | .38 Long Colt | .38 Special |
|---|---|---|
| Case Length | Longer | Shorter |
| Power | More powerful (generally) | Less powerful (generally) |
| Revolver Compatibility | Limited to revolvers designed for it | More widely compatible with revolvers |
| Modern Usage | Less common; primarily historical | Widely used and readily available |
Practical Implications:
-
Ballistics: The .38 Long Colt generally delivers a higher muzzle velocity and greater stopping power compared to the .38 Special, due to its longer case and ability to hold more propellant.
-
Revolver Choice: Many modern revolvers chambered for .38 Special can not safely fire .38 Long Colt rounds. Attempting to do so can result in serious damage to the firearm and injury to the shooter. The reverse isn't typically true, though it's generally recommended to avoid firing .38 Special rounds in revolvers specifically designed for .38 Long Colt to ensure optimal performance and longevity of the weapon.
-
Ammunition Availability: .38 Special ammunition is widely available in various loadings, including target rounds, self-defense rounds, and specialized rounds for law enforcement. .38 Long Colt ammunition is less common and generally more difficult to find.
Conclusion:
While the terms ".38" and ".38 Special" are frequently used interchangeably, understanding the subtle but significant differences between the .38 Long Colt and the .38 Special cartridges is paramount for firearm safety and responsible gun ownership. Always verify the specific cartridge your firearm is designed to handle before firing. Consult your firearm's manual and seek expert guidance if you have any doubts.
