What A Cutie! SIG Sauer Unveil The Ultra-Compact MPX Copperhead

Sig Sauer MPX Copperhead

With SBRs and compact AR-style guns being the rage nowadays in real steel and airsoft, SIG Sauer just went even more ultra-compact. Their MPX line, which they revealed a few years ago, already feature compact versions, but with the announcement of the MPX Copperhead, they have a very compact 9mm that we sure would like to see an airsoft version.

The SIG Sauer MPX Copperhead is 8 inches in height and has an overall length of 14.5 inches. The company says it features a monolithic Elite Series Cerakote finish upper receiver that has an integrated stock knuckle lower. The barrel is 3.5 inches with integrated muzzle brake. It comes with the new SIG SAUER Pivoting Contour Brace (PCB) installed with the aim of giving pistol users a brace. This brace easily adapts to the movement of the shooter’s arm with a patented swivel operation for rapid deployment.

“The MPX Copperhead considerably reduces the length, width, and size of the MPX platform making it the most compact addition to the MPX family of firearms,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc., in a press release. “The Copperhead is the perfect combination of the features and performance our consumers expect from a SIG MPX in a compact package.”

Back to the stabilizing brace found in the rear of the MPX Copperhead. It rides on two rails and can be adjusted for just two positions: fully extended or fully retracted.  It has full ambidextrous controls and can accept current MPX magazines. This gun operates from a fully-closed and locked rotating bolt, providing enhanced reliability and is safer to use. The  short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve.

Here are the specs of the MPX Copperhead:

  • Total length: 14.5”
  • Barrel length: 3.5”
  • Barrel Twist: 1:10”
  • Weight: 4.5lbs
  • Finish: Cerakote E190
  • Caliber: 9mm Luger
  • MSRP: $1835.00
