40 S&W Ammo

.40 S&W is a handgun round developed by both Smith & Wesson and Winchester as a joint project to create a lower velocity 10mm firearm round. It uses .40-inch bullets in a rimless straight-cased configuration. The round was created in 1990 in an effort to achieve similar performance to the FBI's prior 10mm round but in a 9mm-size gun frame.

There is no difference between .40 and .40 S&W. The two names can be used interchangeably because they refer to the same round. Using .40 instead of saying .40 S&W is just a truncated use for simpler language, much like using auto instead of ACP.

The .40 S&W is often billed as an intermediary round, offering the best of both worlds between 9mm and .45 ACP. This is actually fairly accurate when it comes to the price of the round. The price of .40 S&W rounds are comparable to both calibers and is typically within a few cents of each.

While relatively new to the market, the .40 S&W has become immensely popular in its short lifespan. Because of this, it's very easy to find for purchase across the spectrum of ammo providers. Most retailers will have some in their inventories, especially online vendors.

Numerous guns have been developed to fire .40 S&W since its inception. Many quality manufacturers like Glock, Sig Sauer, and Smith & Wesson all have pistols chambered in the caliber. These models are among the ever-increasing number of firearms being produced to fire the .40 S&W round.

Most definitely. Thanks to its popularity since its introduction, the .40 S&W round is easily found in bulk. Most ammunition retailers and online sellers have plenty of choices for bulk purchases available. Both self-defense and target ammunition are available for bulk here at Ammunition Depot.
