The SIG SAUER MPX Copperhead is a revolutionary small arms platform, bringing a combination of modern design and cutting-edge materials to the semiautomatic handgun and carbine markets with its revolutionary features. It is a highly maneuverable, accurate, and reliable weapon with a design that has been proven across the board in professional, law enforcement, and sport/competition shooting circles.

The SIG SAUER MPX Copperhead is built around a gas-operated operating system with closed-bolt direct impingement, providing excellent accuracy and reliability when fed from its box-style magazine. As a relatively lightweight and compact firearm, the MPX Copperhead weighs just 6.85-lbs and measures a total length of 35.5-inches, making it perfect for use in personal defense and close-quarters combat. The frame of the MPX Copperhead is made from high-strength, corrosion-resistant stainless steel, which is finished in a black anodize coating for added durability.

The SIG SAUER MPX Copperhead is chambered in 9x19mm and is capable of firing in semi- or full-automatic mode, allowing it to be used in both recreational and tactical scenarios. The MPX Copperhead includes a 16-inch, cold-hammer-forged barrel with a protective coating to give it a durable and erosion-resistant finish. The barrel is fitted with a silent captured spring recoil system to reduce noise and felt recoil, and it is also threaded to accept the use of a sound or flash suppressor.

The Copperhead includes four Picatinny rails for easy customization—a 13" upper rail, 4" side rails and a 5" integrated rail—allowing users to mount compatible accessories such as weapon lights, optics, and grips to the firearm. It is also equipped with an adjustable AR-style pistol grip, with the triggerguard being compatible with aftermarket customizations.

Finally, the MPX Copperhead utilizes SIG’s unique Enhanced Trigger Geometry (ETG) technology— utilizing a flat-faced trigger designed to reduce user fatigue over extended periods of use, while its crisp break and short reset provide quick and precise follow-up shots.

In conclusion, the SIG SAUER MPX Copperhead is an exceptional, high-performance small arms platform that is capable of making excellent use of a variety of ammunition in any environment. Its ergonomic design, durable construction, and reliable gas-operated operating system make it a perfect choice for both recreational uses and tactical scenarios, while its customizability and enhanced trigger geometry technologies spend it above and beyond the competition. With a price tag of around $1850, the Copperhead is certainly not a cheap firearm, but it is certainly a worthy investment and will provide shooters of all level productivity and reliability time after time.
