Hands On – SIG MPX Copperhead

Although it came first to market, the SIG MPX has screamed for an ultra compact treatment like its big brother, the MCX Rattler. And that’s just what SIG did when they created the MPX Copperhead.

I got the chance to take a full auto version of this 9mm to the range last summer. It boasts a 3.5″ barrel within a one-piece upper receiver and an overall length of 14.5″ in its pistol configuration with new proprietary collapsible SIG stabilizing brace. The Copperhead in the photos is fitted with their standard collapsible stock. Additionally, the Copperhead will be offered in a Tan cerakote.

    Wow, looks slick and I dig the one piece upper. Does it retain the barrel change feature?

    This looks like it could be a handy pistol caliber PDW option.

    I just wonder if the pistol grip is replaceable/compatible with AR pattern grips.
