357 Sig: Old Ammunition Has Value

Compact .357 SIG with ammunition

SIG SAUER and Federal Premium Ammunitions introduced  .357 SIG ammunition in 1994. The cartridge has a rimless, bottlenecked case. The companies wanted to have the same power as the .357 Magnum, but designed it for use in a semi-automatic pistol. The ammo was launched four years after the .40 S&W, a round created for the FBI.  The .40 S&W has the stopping power of a .45 ACP and ease of use of the 9mm parabellum. Although the .357 SIG performed better than the .40 S&W, it never became as popular with law enforcement or the public.

.357 SIG Design

The designers took a .357 bullet and pared it down to .355-inch to make it easier to handle. The .357 SIG was the first commercial bottleneck ammunition sold since the 1960s. The cartridge base diameter is .424-inch, the case is .864-inch in length. The full length of the cartridge is 1.140-inches.  It uses a bullet with 125-grains, the same as a .357 Mag. It has a velocity of 1,350 feet per second (fps), and muzzle energy of more than 500 foot pounds (ft·lbs). The round is also referred to as the .357 SIG, .357 Sig, and 9x22mm.

.357 SIG vs. .357 Magnum

Although the .357 SIG never became popular, it remains a favorite of some law enforcement agencies, as well as target shooters and those who are in range training or carry for self-defense. Unlike other small rounds, the .357 SIG has the ability to cause hydrostatic shock, immediately disabling or fatally wounding its target upon impact. While the .357 Magnum remains more popular, the .357 SIG still packs a punch. The smaller casing makes it optimal for self-defense.

Popular Firearms

Because of its lack of popularity, the .357 SIG has a limited number of firearms chambered for the ammunition. They include the full size SIG SAUER P226 (combat pistol), the compact 229, the 320 (designed for concealed carry), as well as a traditional 1911. Glock models include the full-size G31, compact G32, and G33, designed for concealed carry. S&W has discontinued their .357 SIG pistol from their M&P line.

Uses for the .357 SIG

Law enforcement agencies prefer the 9mm, but many still use the .357 SIG as a standard issue ammunition for the SIG SAUER and Glock pistols. The Texas Highway Patrol took it on in 1995, followed shortly by The Texas Department of Public Safety (DPS). The DPS used the .357 SIG as standard issue from 1998-2013. Other notable agencies include the Bureau of Industry and Security, Federal Air Marshal Service, The United States Secret Service, Pennsylvania Game Commission, and the Texas Rangers. It is also used by several state police troops and highway patrol units, including Mississippi, Montana, New Mexico, North Carolina, Oklahoma, Rhode Island, South Dakota, Tennessee, and Virginia.

Many experts refer to the .357 SIG as being obsolete but the fact that it is still used by so many law enforcement agencies shows that it has its place in the market.

 

 

 

.40 Cal S&W Replaced the .38 Special

.40 Cal S&W comparison

Designers from Smith & Wesson and Winchester introduced the .40 Cal S&W cartridge in 1990. The ammunition was designed along with Smith & Wesson’s Model 4006 pistol, months after receiving a request from the FBI for a new type of ammunition.  However, one week before the ammo went to market, Glock introduced the Glock 22 and Glock 23, chambered in .40 cal.

Development of .40 Cal S&W

The Federal Bureau of Investigation requested that S&W create a new ammunition to replace their standard issue sidearms. The request came after a 1986 shootout in Miami. Two bank robbers confronted FBI agents and a shootout ensued. During the standoff, agents realized that they could not reload and fire fast enough to take down the criminals. The bank robbers killed two FBI agents and wounded five. Agents killed the bank robbers.

The FBI stated that the .38 Special revolvers were no longer sufficient for their agents. They requested to replace them with semi-automatic pistols. Agents asked Smith & Wesson to develop a new type of ammunition that could be retrofitted into 9mm semi-automatic handguns. S&W and Winchester developed the .40 Cal, based on 9mm and .45 ACP ammunition. The new medium-velocity round had the same accuracy as a 9mm while using the specs of a 10mm load. The FBI approved the ammo and hoped it would prevent another catastrophe like the one in Miami. Shortly after the FBI adopted the round, law enforcement agencies across the country switched to the new ammo. Although the FBI no longer uses the .40 Cal S&W, it endorses the Sig Sauer P226 and P228, both of which can be chambered in 9mm and .40 cal. The U.S. Coast Guard uses the .40 Cal S&W as a standard issue sidearm.

Specifications

The .40 Cal S&W is a medium velocity cartridge ideal for concealed carry and self-defense. It uses a 0.40-inch diameter lead bullet that can range from 105 to 200 grains. The casing measures .85 inches long, .424-inch at the base. The cartridge has an average pressure of 35,000 psi. The muzzle energy is higher than the standard pressure of a .45 ACP, with 350-500 foot-pounds of energy. Ballistics performance tests in the 1980s and 1990s prompted experts to refer to the .40 Cal as “the ideal cartridge for personal defense and law enforcement.”

Use for Self-Defense

Civilians choose the .40 Cal for the fact that it is easy to use. It has a light recoil, which makes it an accurate round. Self-defense and home defense situations require accuracy and adequate stopping power. Consumers can choose a variety of options for design and bullet weight. Shooters choose the .40 Cal S&W for the same features that were required by the FBI and law enforcement, including a high magazine capacity, light recoil and high muzzle energy. Although the .40 Cal S&W isn’t a highly sought after ammo, most firearms manufacturers offer compact and sub-compact models chambered for the round.
