SIG Sauer MPX Copperhead 9mm Pistol, 3.5″ Barrel, Coyote, 20-Round

Description

SIG Sauer MPX Copperhead 9mm Pistol, 3.5" Barrel, Coyote, 20-Round

The SIG MPX Copperhead is SIG’s 9mm piston firearm. The MPX runs a short-stroke piston and AR-style controls on 9mm, with magazines that are SIG’s own MPX pattern.

It does not take Glock, P320, or AR-15 magazines. The top rail is optic-ready. A factory optic is not installed. Pistols ship with SIG’s folding PCB. The SBR uses a stock and needs NFA paperwork.

This configuration

If you want more barrel and a 35-round magazine, that is the MPX K. If you want a 16 in. carbine with a stock, that is the PCC. Copperhead is the PDW-size pistol in coyote, with the PCB folded or deployed as you carry it. SIG’s PCB is the folding arm brace that ships on this pistol. This Copperhead ships to a licensed FFL as a pistol. If you want a folding stock on a 4.5 in. MPX, that is the SBR, and it needs NFA paperwork.

What ships
