CAA MCK for SIG P320

The CAA MCK for P320 brings the popular conversion kit concept to SIG's modular pistol platform. Like the Glock version, the P320 MCK clamps around the complete pistol without permanent modification, providing stock stability and extended rail space. The P320 can be removed quickly when pistol configuration is preferred.

The P320 MCK accommodates full-size, compact, and carry P320 variants in 9mm and .40 S&W, but CAA excludes M17, M18, RX, VTAC, X Series, external-safety, AXG/AXG Pro, threaded-barrel, suppressor, and suppressor-height-sight configurations. The extended Picatinny rail provides ample space for optics, and the integrated sights serve as backup. The folding stock/brace design keeps the package relatively compact when not in use.

For P320 owners who want to try the chassis concept without committing to the Flux Raider's premium pricing, the CAA MCK offers an entry point. While it lacks the Raider's refinement and purpose-built design, the MCK provides genuine stability improvement at significantly lower cost. Many shooters start with an MCK before deciding if they want to upgrade to a dedicated platform.
