38 Special vs 357: Key Differences Explained

If you quickly glance at 38 Special ammo and 357 Magnum ammo, you might not notice any differences and think they were the same round. Although they are close in overall length, the 38 Special and 357 Magnum are extremely different.

In this article, we’ll look at why 38 Special ammo can be fired in a 357 Mag firearm (but not the other way around), as well as compare the two rounds’ recoil, stopping power, self-defense viability, and cost.

Let’s take a deeper dive into these two legendary revolver cartridges and discover what’s so great about wheel guns!

What’s the Difference Between 357 and 38?

The “38” in 38 Special comes from the diameter of its loaded case: .38 inches. Alternatively, the 357 Magnum is named after its bullet diameter, which is the more standard method of cartridge nomenclature.

A cartridge’s caliber often begins its name. Take the 45 ACP, for example, which fires a .45 caliber bullet, or the 40 Smith & Wesson (aka “.40 cal”).

Despite their different names, the 38 Special and 357 Mag both fire identical .357″ diameter bullets.

(The 38 Special is frequently confused with the 38 S&W. See our 38 Special vs. 38 S&W comparison for the key differences between these distinct cartridges.)

The 38 Special and 357 Mag’s case dimensions are identical except in length. The 357 Magnum’s shell is 0.135” longer. That brings A LOT of new shooters to the question:

Can a 38 Special Revolver Fire 357 Magnum Rounds?

NO! You should NEVER fire a 357 Magnum round in a 38 Special revolver or carbine.

A 38 Special revolver is NOT rated to handle the higher pressure 357 Magnum produces. You can safely fire lower-pressure 38 Special in any 357 Magnum firearm, but the opposite is not true.

Which Is Right for You: Use-Case Comparison

38 Special vs. 357 Cartridge Spec Differences

Looking at the spec chart, you’ll notice that the 357 Mag and the 38 Special are almost identical except for two major dimensions. The case length of the 357 Magnum is 1/8 of an inch longer and has a maximum pressure that is twice that of 38 Special. This is the reason that you should never fire a 357 Mag out of a 38 Special revolver because the chamber pressure of the 357 can cause a catastrophic failure that could damage the firearm and/or the shooter.

To prevent this from happening, Smith and Wesson elongated the 357 Magnum case so that it would not chamber in a 38 Special cylinder or in a 38 Special lever-action carbine.

As both cartridges headspace off the rim, you can load 38 Special into a 357 Magnum revolver without issue.

Recoil

The amount of recoil a shooter’s wrists will have to endure will be dependent upon several criteria: handgun weight, muzzle velocity (FPS), and bullet weight.

As the 38 Special and 357 Mag fire the same bullet diameter, the bullet weight that each fires will be the same. Handgun weight is up to the personal choice of the shooter, as a lightweight Taurus 856 snubnose will have more felt recoil than a Smith and Wesson Model 629 6-inch barreled steel hunting revolver.

Therefore, the determining factor when it comes to recoil will be the muzzle velocity. And when it comes to being the King of FPS, the 357 Magnum takes the crown.

Modern 357 Magnum ammo is designed to fire a 158-grain bullet at a muzzle velocity of 1,235 FPS and a target-thumping 535 ft-lbs of muzzle energy. Compare that to the 38 Special, which fires the same bullet weight at 755 FPS and has a muzzle energy of 200 ft-lbs, which is less than a 45 ACP.

The ballistics numbers simply don’t lie – 357 Magnum loads are high velocity and will have considerably more recoil than a 38 Special. Manufacturers like Remington and Hornady offer a wide range of 357 Magnum loads optimized for everything from target shooting to personal defense.

Because of this, many shooters opt to practice using the 38 Special cartridge as it has less recoil and is more comfortable to shoot, then load up for personal defense with jacketed hollow point (JHP) 357 Magnum rounds. For affordable practice ammo recommendations, see our guide to the best 38 Special ammo for target practice.

Recoil is felt hardest in a lightweight snubnose, where there is little gun mass to soak it up. If that’s your carry revolver, our picks for the best 38 Special ammo for snubbies cover the loads that stay manageable out of a 2-inch barrel.

Stopping Power

Stopping power is always a subjective subject as it cannot be quantified. And if you want to talk about controversy, look no further than firearms forums and do a handgun caliber search. You’ll find proponents of each caliber who are willing to come to digital blows to defend their favorite handgun cartridge.

However, when it comes to 357 Magnum vs 38 Special, the ballistics numbers tell the tale. Although it’s not double, 357 Magnum loads simply outperform 38 Special in every category…and it does so by a country mile.

38 Special +P ammo does help close the gap, but even then, it’s still not even close to coming to the raw, unadulterated power offered by the 357 Mag. The 357 simply has more muzzle velocity, energy, and better terminal ballistics compared to the 38 Special.

Does that mean the 38 Special is ineffective? Definitely not!

As mentioned before, 38 Special +P is an excellent personal defense round and it will stop the bad guy so long as you do your part.

However, the 357 Mag will just do it a bit better, so it gets the nod for stopping power.

Trajectory

Trajectory is not something that we often discuss when comparing handgun rounds. However, as the 357 Magnum can be used for longer-range shots, it’s something that should be discussed. As the 357 Magnum has higher muzzle velocity, it has a flatter trajectory compared to 38 Special.

The high velocity allows the bullet to reach its target faster, reducing the amount of time gravity has to pull the projectile towards the earth. This makes 357 Magnum a potent hunting round.

Hunting

The 357 Magnum is an extremely capable hunting round, regardless of if it’s fired from a revolver or a rifle.

It is more than powerful enough to take down a whitetail and even a black bear (though I’d prefer a 44 Magnum for this) with proper shot placement and bullet selection. If your state allows it, you can take your 357 Magnum revolver out into the woods for a different kind of whitetail hunt than you’re used to.

As always, do your research on the ideal hunting round, as you want excellent penetration and expansion to ensure a clean kill.

Self-Defense and Concealed Carry

When it comes to carrying a concealed handgun for personal defense, there are many aspects to consider, including ease of carriage, accuracy, effective terminal ballistics (sorry, 22 LR), and reliability.

Many shooters rank those categories in different orders. However, I believe the most important thing you should prioritize is carrying a handgun that you will actually EDC consistently. Herein lies the problem many shooters don’t like to discuss: the relationship between handgun weight and ease of concealed carry.

And trust me, I get it.

I’m sure there are some hardcore CCW permit holders out there who carry a medium to full-size revolver every day. If that’s you, I salute you. But it takes a lot of planning for your wardrobe and carry system to handle all that weight without printing when you bend over or sit down.

Although I believe the ideal choice would be to carry a 357 Magnum, it isn’t necessarily the better one. If you can’t hit the broadside of a barn due to recoil anticipation, then a weaker round would serve you far better while your life’s on the line.

You need to be honest with yourself about your marksmanship and trigger discipline while firing 357 Mag vs. a 38 Special (or its more powerful variant, the 38 Special +P). If you are more accurate with the +P load – or don’t have the skill to handle a full-power 357 Mag – then you should carry 38 Special +P with confidence.

For specific load recommendations in that role, see our guide to the best 38 Special ammo for self-defense.

For home defense, I thoroughly endorse using a 357 Magnum. When my family’s life is threatened, I want as much power as I can handle to stop the threat as quickly as possible.

Some naysayers might contest that the 357 Magnum has a propensity to over-penetrate. This may be true with lead round nose (LRN), full metal jacket (FMJ), or semi-wadcutter (SWC) ammo. However, with premium hollow point ammo such as Winchester Defender, Remington Golden Saber, or Speer Gold Dot, you will significantly reduce (albeit not eliminate) the risk of over-penetration.

Cost and Availability

When it comes to price, 38 Special is nearly always less expensive than 357 Mag.

357 Magnum ammo prices are about 50-75% higher (if not double) those of 38 Special.

This trend is consistent with handgun prices. Typically, 38 Special revolvers are about 50% cheaper because they have lighter construction (as the 38 is a lower-pressure round). In contrast, the high-pressure 357 Mag requires rigid construction and a stronger frame to handle its strong pressure and recoil.

Any revolver manufacturer should offer at least one model chambered for either cartridge. The 38 Special and 357 Mag are the two most popular revolver calibers. As such, you will not lack for options when it comes to handguns.

Smith and Wesson, Colt, and Ruger are two of the premier revolver manufacturers, and their prices reflect this heritage. For more budget-friendly revolvers, you can look to firearm companies like Taurus, EAA, and Charter Arms.

As for ammo, every manufacturer has multiple lines of 38 Special and 357 Magnum. You will not lack for options when it comes to factory loads for either cartridge.
