Can You use 380 bullets in a 9 mm gun?

The Straightforward Answer

No, you cannot use.380 bullets in a 9 mm gun. The reason is that they are not designed to fit and operate within the 9 mm pistol or revolver. Both calibers have distinct design differences, and firing.380 bullets in a 9 mm weapon is unsafe and potentially catastrophic.

What is the difference between 380 and 9mm

Here is a summary of the differences:

• Cartridge diameter:.380 cartridges have a diameter of 9.02mm (0.355 in), while 9mm Parabellum cartridges have a diameter of 9.92mm (0.391 in). The 9 mm has a larger diameter and requires a different design in the weapon’s barrel.
• Case length:.380 cartridges have a case length of 17.30mm (0.680 in), while 9mm Parabellum cartridges have a case length of 20.55mm (0.808 in). This means the 9mm requires a longer and deeper chamber to accommodate its slightly longer and thicker casing.
• Bullet seating depth: Due to the size differences, the seating depth for the bullet in a 9 mm cartridge is also different from the.380. Proper seating depth is essential to ensure reliable ignition, firing, and accuracy.
• Chamber throat design: The design of the chamber throat (where the cartridge is fed) also varies between the two calibers. The throat on a 9mm chamber is broader to accommodate the wider casing, while a.380 chamber has a narrower throat.
• Expansion ratios:.380 cartridges cannot generate the same amount of expansion as 9mm cartridges. 9mm bullets can achieve up to 400 meters per second (1,312 ft/s) while.380 bullets max out at around 200 m/s (656 ft/s). This expansion rate can cause issues if attempted in a 9 mm gun.

Safety Considerations

Using.380 bullets in a 9 mm gun can have devastating consequences, including:

• Catastrophic failures: The misshapen or expanded casing may not extract properly from the chamber, potentially jamming the weapon and risking accidental discharges.
• Accidental ignition: With a larger chamber designed for 9mm rounds, there is a heightened risk of accidental ignition caused by misaligned or offset cartridges.
• Malfunctions: The incompatibility between the two calibers can lead to jams, stovepipes, and misfires, rendering the weapon unusable and dangerous to handle.
• Gun damage: Using a different caliber in an ill-advised manner can compromise the weapon’s mechanical integrity, leading to expensive or potentially fatal repairs.

Conclusion

In conclusion, using.380 bullets in a 9 mm gun is not safe. The differences in size, design, and intended operation make it unsuitable and potentially dangerous to try to fire.380 ammunition in a 9mm pistol or revolver. If you own a weapon for either caliber, make sure to only use compatible ammunition to avoid damaging the gun, causing injury, or worse. Remember, it’s essential to always prioritize safety when handling firearms and follow manufacturer recommendations.
