Are There 9mm Revolvers? The Surprising Answer
The short answer is: yes, but they're rare and often not what you expect. While the image of a revolver typically conjures up images of .38 Special or .44 Magnum, the 9mm cartridge can be chambered in a revolver, although it's less common than other calibers. Let's delve into why this is the case and explore the nuances of 9mm revolvers.
Why 9mm Revolvers Aren't as Common
The relative rarity of 9mm revolvers stems from a few key factors:
-
Cartridge Design: The rimless design of the 9mm cartridge presents challenges for revolver mechanisms. Revolvers traditionally rely on the rim of the cartridge to facilitate extraction and reloading. The lack of a rim in 9mm requires specialized mechanisms to ensure reliable function.
-
Established Calibers: Revolvers have a long history with cartridges specifically designed for their action. Calibers like .38 Special and .357 Magnum have been optimized for revolver use for decades, offering proven reliability and performance. The established market for these calibers has limited the demand for 9mm revolver development.
-
Semi-Automatic Dominance: The 9mm cartridge has found its niche primarily in semi-automatic pistols. These firearms offer higher capacity magazines and are generally more efficient for firing the 9mm round. This has further reduced the incentive for manufacturers to invest heavily in 9mm revolvers.
Types of 9mm Revolvers (or Close Cousins)
While dedicated 9mm revolvers are scarce, you might encounter these variations:
-
Converted Revolvers: Some custom gunsmiths specialize in converting existing revolvers to fire 9mm ammunition. This typically involves modifications to the cylinder and sometimes other internal components. These are not factory-produced and often come with a higher price tag.
-
Moon Clips: A more common workaround involves using moon clips. These are thin metal clips that hold the 9mm cartridges, providing a rim-like structure for easier extraction. This allows some revolvers (often those designed for other calibers) to fire 9mm rounds with a degree of modification. However, using moon clips adds an extra step in reloading and can potentially impact reliability if not used correctly.
-
Rare Factory Models: A handful of manufacturers have historically produced limited runs of 9mm revolvers. These are often collector's items and can be difficult to find on the market. Researching specific manufacturers and their historical catalogs might reveal some examples.
Considerations for 9mm Revolver Owners (or those considering one)
Should you find yourself considering a 9mm revolver, remember these points:
-
Reliability: Due to the cartridge design, you should prioritize reliability when choosing a 9mm revolver, whether it's a conversion or a rare factory model. Test it thoroughly before relying on it for self-defense or other critical applications.
-
Availability: Ammunition for 9mm revolvers (particularly those using moon clips) might be less readily available than for more standard revolver calibers.
-
Maintenance: Proper maintenance is crucial for any firearm, but especially for those with specialized mechanisms or adaptations. Regular cleaning and inspection are essential for ensuring continued reliable operation.
In conclusion, while not prevalent, 9mm revolvers do exist. They're often unique, specialized firearms for niche markets or custom builds. Before purchasing one, carefully consider the practical implications of their rarity, the potential challenges in finding ammunition and parts, and the importance of ensuring reliable operation.
