If you are looking for a good round to use for duty and protection functions, the .357 SIG cartridge is definitely the best cartridge to go for. The .357 SIG cartridge has remarkable ballistic performance when compared to other cartridges on the market. 

To be able to fire the .357 SIG cartridge, you will need a good pistol to bring out the full potential of the .357 cartridge. Before we go through the list of some of the best .357 SIG pistols, it is helpful to understand some things about the .357 SIG cartridge and what to look for when choosing the best pistols for the .357 SIG. 

Definition: The .357 SIG Pistol

The .357 SIG cartridge is one of the products of the famous manufacturer, SIG Sauer, back in the early 1990s. This round was a collaboration between SIG Sauer and Federal Premium Ammunitions or was known as Federal Cartridge. It was made to be an alternative to the .357 Magnum round but the time that it was released was not the best time even though the .357 SIG cartridge performed better than the .40 S&W and 9mm. 

How good is a .357 SIG Gun?

The .357 SIG cartridge does deliver some exceptional ballistics, but some may wonder just how good it is and we are going to take a dive into it. The muzzle velocity of a round of 125-grain .357 SIG is able to reach up to 1475 feet per second. As for the muzzle energy of a 125-grain .357 SIG bullet, it can reach up to 620 foot-pounds of energy.

The muzzle velocity and energy that is recorded is consistent throughout standard chamber pressure and a 4-inch barrel. When in comparison with the .357 Magnum revolver with a 4-inch barrel, the performance of the .357 SIG is on par. If you were to compare the power of a 9mm round or a .40S&W round to a .357 SIG round, the .357 SIG round with its 4-inch barrel is significantly more powerful. 

Let’s Be Real: The Disadvantages of .357 SIG Pistol

While the .357 SIG cartridge can achieve a good velocity of up to 1475 feet per second, there are still a number of drawbacks of this cartridge when compared to other common cartridges like the .40 S&W, 9mm and .45 ACP. 

Firstly, due to the high chamber pressure of 40,000 psi, the wear and tear of your pistol are very high. Both .40 S&W and the 9mm round, and also the .45 ACP has a significantly lower chamber pressure that causes less wear on your pistol. Another disadvantage of the .357 SIG  cartridge is the price of it. Besides,  unlike .45 ACP with a smaller round and obviously, you can’t easily find it at the store shelves of a gun store, you will have to pay much more to access this handgun round. 

Important Factors of The Best .357 SIG Pistol Options

In order for you to be able to pick the right pistols, there are some things that you need to look out for when browsing through some of the best pistols on the market. Here are the things to look for in a .357 SIG pistol. 


The most important criteria when looking for .357 SIG pistols is that it has to be able to handle the .357 SIG ammunition. If the guns are not made for this caliber then it’s not really a .357 SIG pistol. Not all guns are made for this type of ammunition and it is very likely that guns that are made for other types of ammunition cannot handle the .357 SIG ammunition. 

Because of the differences in design by different manufacturers, not all the guns are able to handle the pressure that is required to fire this round. On the bright side, .357 SIG pistols have barrels that can be customized to handle other types of ammunition. 


Using different ammunition will change the size of magazines and the impact of that is the change in the capacity of your pistol. How many rounds a person would like to have in their pistol is a personal preference, there is no good or bad capacity for your mag so it will have to depend on what application you are using it for. 

Having a higher capacity means you can fire off more rounds and can give you more oomph when firing at the range and can also give you the confidence knowing that there are many rounds in your pistol. The trade-off of having more ammo is the weight of the pistol will be increased so make sure you find a good balance. 

Accessories Availability

The availability of parts for guns is also an important factor in deciding whether it is a pistol that is worth your money. Some things that you should take into consideration is how easily you can gather parts like a different length of the barrel or barrels that can handle different ammunition. If you are unable to get the accessories that you want easily, then you should go for other options. 

Size and Weight

The overall size and weight of pistols can affect comfort when you are using it. An unloaded pistol and a fully loaded one can give you a different feeling when you hold it. Which is why it is important to have guns that you can hold comfortably in your hand and doesn’t make you feel uncomfortable after using it. The size and weight of pistols is also an important factor, especially if you are planning to use it as a concealed carry.

Trigger Pull

The final thing that you should keep an eye out for is the trigger pull of the pistol. Even if you have just bought it, you will still need some time to get used to it. A good way of making sure that the trigger is the right for you is to just test it out before buying it. Some may prefer a lighter pull while some may want the pull weight to be on the heavier end.

Frequently Asked Questions (FAQs)

Is .357 SIG better than 9mm?

Depends. When comparing a 9mm projectile to a .357 SIG, the 9mm rounds have more magazine capacity and lesser recoil. In comparison to .357 mag, the 9mm projectile generally produces less muzzle blast and flash compared to a .357 SIG round. However, an advantage that the .357 SIG rounds have is that it is usually 125-grain bullet that is designed to expand at higher velocities and can travel faster than a 9mm+P of similar bullet weight. 

Is the .357 SIG worth it?

If you are looking for something with more power than the 9mm, the .357 SIG will be a great pick. The .357 SIG is also a good pick if you do not want to carry a large-frame pistol around or a revolver with .357 Magnum. However, there are some drawbacks for the .357 SIG round so it’s up to you to decide if the .357 SIG is worth it or not. 

Why is .357 SIG ammo so expensive?

The. 357 SIG is a niche cartridge and delivers similar ballistics as a .357 Magnum. Unlike the .357 Magnum, the .357 SIG is like a premium cartridge that gives good ballistics in a shorter package and that is the reason why the .357 SIG ammo is so expensive. 

Is it safe to fire .357 SIG rounds out of a gun made for .40 S&W or 9mm?

Many manufacturers have addressed this question before and it is the safest to shoot guns that are made for the recommended cartridges. But that doesn’t mean you can’t shoot a .357 SIG in handguns made for .40 Smith & Wesson or 9mm, it just means that the manufacturer is not held responsible if anything were to happen. 

Luckily, there hasn’t been any cases where something bad happened from shooting a .357 SIG out of firearms made for the .40 S&W or 9mm round. However, it is still highly recommended by us and all the manufacturers to shoot the caliber that firearms are made for. 

What are the Difference Between .357 SIG and Magnum?

The .357 SIG round was designed to mimic and replace the ballistics performance of the 357 Magnum for semi automatic pistols. Hence the 357 SIG uses the same bullet sizes as a 9mm but it is in a cartridge casing that resembles the .40 caliber options. The .357 SIG has a sleek bottleneck design which allows easy load into the barrel chamber of your SIG pistol and you’d experience higher velocity.
