Can You Shoot .357 Magnum from a .38 Special Revolver? The Crucial Safety Considerations
The short answer is: yes, but with significant caveats. Shooting .357 Magnum rounds from a revolver chambered for .38 Special is possible, but doing so carries considerable risk and should never be attempted without a thorough understanding of the implications.
This seemingly simple question involves a nuanced understanding of firearm mechanics and safety. Let's break down why it's risky and what you need to know.
Understanding the Caliber Difference
The .38 Special and .357 Magnum cartridges are closely related, both using the same diameter bullet (.357 inches). The key difference lies in the case length and the powder charge.
-
.38 Special: Has a shorter cartridge case, holding a smaller powder charge. This results in lower pressure and velocity.
-
.357 Magnum: Has a longer cartridge case, allowing for a significantly larger powder charge. This leads to much higher pressure and velocity.
The Danger of Mismatched Ammunition
Firing a .357 Magnum round in a .38 Special revolver is dangerous because the magnum round's longer case can potentially cause issues:
-
Increased Pressure: The higher pressure generated by the .357 Magnum round can exceed the design limits of the .38 Special revolver's cylinder and barrel. This could lead to catastrophic failure, such as a burst cylinder, barrel rupture, or the gun splitting apart. These failures can cause serious injury or death to the shooter and bystanders.
-
Cylinder Gap Issues: The cylinder gap, the space between the cylinder and the barrel, might be larger in a .38 Special revolver than is ideal for a .357 Magnum round. This increased gap could lead to excessive gas leakage, resulting in burns and potential damage to the gun.
-
Improper Headspacing: The longer .357 Magnum cartridge might not headspace correctly (align properly) in the .38 Special cylinder. This could cause the round to fire out of alignment, increasing the chance of malfunctions and potential damage to the firearm.
When It Might Be Safe (with Extreme Caution)
Some .38 Special revolvers are marked as being able to fire both .38 Special and .357 Magnum. This marking is crucial. However, even with this marking, proceed with extreme caution. Regularly inspect your firearm for any signs of wear or damage after firing magnum rounds.
Best Practice: Always Check Your Revolver's Markings
Before firing any ammunition in your revolver, always:
- Carefully inspect your revolver's cylinder and barrel for any signs of damage.
- Check the manufacturer's markings on the gun itself. This should clearly state if it's safe to fire both .38 Special and .357 Magnum rounds.
- If unsure, consult a qualified gunsmith. They can definitively determine the firearm's capabilities.

Always follow safe firearm handling practices, and consult with qualified professionals before handling any firearm. This is not a recommendation to fire .357 Magnum rounds in a .38 Special revolver. The risks far outweigh any perceived benefit.
