We shot 28 self-defense loads of 40 S&W ammo into ballistic gel

Smith and Wesson and Winchester partnered to develop 40 Smith and Wesson ammo or the "40 cal" cartridge as a round for law enforcement. Their hope was to create a caliber that could mimic the performance of the FBI's reduced-velocity 10mm automatic round with rounds small enough in physical size to be carried with a medium-frame pistol.

40 S&W quickly caught on and remains a popular caliber for personal protection and range training today. Range shooters will likely opt for full metal jacket (FMJ) rounds with a non-expanding bullet while those seeking a round for protection will want to look at jacketed hollow point (JHP) ammo. In terms of ballistic performance, expect the lighter 40 cal rounds (155-grain) to leave the muzzle at about 1,205 feet per second and the heavier rounds (180-grain) to bring a muzzle velocity of about 1,050 feet per second.

Look for a wide selection of 40 S&W ammo for sale from trusted manufacturers like Federal, PMC and Hornady in the most common bullet types out there today, like full metal jacket (FMJ), jacketed hollow point (JHP) in the categories listed below:

More About 40 S&W Ammo

When Was the .40 S&W Created?

In the world of firearms, the .40 S&W is actually a fairly new cartridge. It was created in 1990 after an infamous shootout between two bank robbers and eight FBI agents. Two agents lost their lives in a gun battle that saw the law enforcement personnel heavily outgunned. Despite being hit by the agents, the bank robbers were able to continue fighting, although they were eventually killed by law enforcement. In the aftermath, the FBI commissioned the production of a powerful cartridge with manageable recoil, giving law enforcement stopping power while allowing for accurate secondary shots. With this goal in mind, the .40 S&W was born.

What Does the “S&W” Mean?

“S&W” stands for Smith & Wesson, the company that was primarily responsible for creating the cartridge. It is common practice, dating back to the 1800’s, to have companies put their names on ammunition. This is seen in rounds like the .223 Remington, .270 Winchester, and 9mm Luger.

How Does the .40 S&W Compare to the 9mm Luger?

While these two cartridges are often compared, due mostly to the overall popularity of both, they are distinctly different products. The biggest difference is size: .40 S&W is noticeably larger than 9mm Luger ammo and has a wider bullet and neck diameter. They do, however, have similar overall lengths. Because of the wider diameters, the .40 S&W generally has higher stats for power. Head to our blog for more on how 40 S&W compares to 9mm.

Is a 10mm Auto the Same as a .40 S&W?

No. While these two cartridges are similar in diameters, they are different in overall length. They both have bullet diameters of .4 inches, but the 10mm Auto has a longer overall length. The result is that the 10mm Auto generally fires at a faster speed and has more power compared to the .40 S&W, assuming the cartridges are loaded with similar bullets. The .40 S&W, however, has lighter recoil. In fact, it was designed to have a forceful impact with lighter recoil, which makes for accurate followup shots.

What Type of .40 S&W Ammo Should I Purchase?

That depends on the purpose for your ammunition. If you are using the cartridges for target practice or competition, you will likely want full metal jacket rounds, which cycle with greater ease and leave less fouling in the barrel. On the other hand, if you are loading your weapon for self defense, you will want expanding rounds, such as jacketed hollow points or jacketed soft-nose bullets.
