Finding information on a ".40 caliber pistol revolver" can be tricky because the vast majority of .40 S&W handguns are semi-automatic pistols. Revolvers, traditionally chambered in larger calibers like .357 Magnum or .44 Magnum, are less common in .40 S&W. However, let's explore this niche area and clarify what options exist, their features, and what to consider if you're interested in such a firearm.
The Rarity of .40 Caliber Revolvers
The .40 S&W cartridge, designed as an intermediate round between the 9mm and .45 ACP, found its popularity primarily in semi-automatic pistols. Its case design and relatively high pressure are better suited to the mechanism of a semi-automatic pistol's slide and recoil operation. Adapting the cartridge to the cylinder and action of a revolver presents design challenges that have historically limited its adoption.
Potential Options and Considerations
While dedicated .40 S&W revolvers are rare, there are a few ways to potentially use .40 S&W ammunition in a revolver:
1. Custom Conversions:
Some gunsmiths specialize in custom revolver work. It might be possible to have a revolver chambered for a similar cartridge (like a .400 Cor-Bon, if one exists that's compatible with the action) or even to have a revolver's cylinder modified, though this is a complex and potentially dangerous undertaking requiring significant expertise. This is not recommended unless you are working with a highly reputable and experienced gunsmith. Modifying a firearm incorrectly can lead to serious injury or death.
2. Moon Clips:
Moon clips are metal devices that hold cartridges in a cluster, allowing them to be loaded into revolvers not originally designed for that specific caliber. While moon clips might theoretically work for .40 S&W in some revolvers (like possibly some larger-framed .357 Magnums), it's not a common practice and could pose challenges in terms of reliable feeding and potentially damaging the cylinder or the firearm itself. Using moon clips requires careful consideration and a thorough understanding of the limitations.
Choosing a Revolver: Alternatives to .40 S&W
If you're looking for a revolver, focusing on readily available calibers will offer a much wider selection and avoid the risks associated with modifications or unconventional ammunition usage. Popular revolver calibers include:
- .38 Special: A versatile and widely available cartridge with a wide range of ammunition options.
- .357 Magnum: More powerful than the .38 Special, offering increased stopping power, but with a more significant recoil.
- .44 Magnum: A very powerful cartridge, typically reserved for larger, heavier-framed revolvers.
- .45 Colt: Another powerful and classic revolver cartridge with a long history.
Before purchasing any firearm, ensure you comply with all applicable federal, state, and local laws and regulations. Seek professional training from certified instructors on safe gun handling, storage, and use.
