Design and Ergonomics

The Copperhead’s PDW pistol grip and short 3.5″ barrel create a balance between concealability and control. The Coyote Elite Series Cerakote provides a durable finish suited for regular field use and low-maintenance carry. At a price of $1516.99, it occupies a premium segment where fit, reliability, and parts commonality with other Sig MPX platforms are key selling points.

Controls and Modularity

Controls are intuitive and mirror modern defensive pistols and SBR-style platforms, allowing rapid transition for users familiar with the MPX family. The 20-round magazine capacity extends practical firepower in a compact chassis without sacrificing reload ergonomics.

Ballistics and Practical Use

Chambered in 9mm, the Copperhead leverages widely available ammunition with manageable recoil and proven terminal performance for self-defense and training. The 3.5″ barrel strikes a pragmatic compromise: it shortens overall length for confined-space handling while retaining acceptable velocity for common 9mm loadings. Whether you’re focused on defensive readiness or high-volume range days, this configuration is versatile.
