Choosing the right cartridge can make all the difference in shooting performance and personal satisfaction. For those considering the 9mm Largo or the .38 Super, understanding their nuances is crucial. This in-depth comparison will explore both rounds, highlighting their strengths and weaknesses, to help you make an informed decision.
Ballistics: A Head-to-Head Comparison
Both the 9mm Largo and the .38 Super are powerful cartridges, but their ballistics differ significantly.
9mm Largo:
- Caliber: 9mm (.355 inches)
- Case Type: Straight-walled, bottlenecked.
- Velocity: Typically ranges from 1000 to 1200 feet per second (fps), depending on bullet weight and barrel length.
- Energy: Moderate, generally lower than the .38 Super.
- Recoil: Relatively manageable, making it suitable for various firearm platforms.
.38 Super:
- Caliber: .355 inches (same as 9mm Largo, but a different case design)
- Case Type: Straight-walled, rimless bottlenecked.
- Velocity: Typically ranges from 1100 to 1400 fps or higher, offering a noticeable increase in speed compared to the 9mm Largo.
- Energy: Higher than the 9mm Largo, resulting in greater stopping power.
- Recoil: Noticeably sharper than the 9mm Largo due to its higher velocity.
Cartridge History and Availability: Tracing Their Origins
The 9mm Largo and .38 Super boast distinct historical backgrounds, influencing their current availability.
9mm Largo's Legacy:
The 9mm Largo, also known as the 9x23mm Largo, has a rich history originating in Spain. While once widely used, its popularity has waned, making it less common than the .38 Super in modern-day ammunition markets. Finding 9mm Largo ammunition can sometimes be challenging compared to more popular calibers.
.38 Super's Enduring Popularity:
The .38 Super Automatic Cartridge, developed in the early 20th century, gained considerable popularity as a law enforcement and self-defense round. Its higher velocity and energy made it a favorite in semi-automatic pistols. Its sustained popularity ensures better availability of ammunition and a wider selection of firearms chambered in this caliber.
Firearms Compatibility: Finding the Right Fit
Firearm compatibility is a significant factor to consider. Both cartridges are typically used in semi-automatic pistols, but their specific compatibility differs.
9mm Largo's Limited Compatibility:
The 9mm Largo's declining popularity means that fewer modern firearms are chambered for it. You will likely find it primarily in older or specialized handguns. This limited compatibility may impact your choice if you need access to a wider range of firearms.
.38 Super's Broader Appeal:
The .38 Super enjoys broader compatibility, with several manufacturers still producing firearms chambered for this cartridge. This wider compatibility provides more options for shooters, accommodating diverse budgets and preferences.
Conclusion: Making the Right Choice
The choice between 9mm Largo and .38 Super hinges on several key factors. If you're drawn to a historic cartridge with moderate recoil and are willing to work with a narrower selection of firearms, the 9mm Largo might be interesting. However, if ammunition availability, higher velocity, and a wider range of compatible firearms are priorities, the .38 Super presents a more practical and readily accessible option for modern shooters. Ultimately, the "better" cartridge depends entirely on the individual's needs and preferences.
