This is a Sig Sauer MPX Essentials Kit with three (3) 20-round magazines and a triple mag pouch
No MPX kit is complete without a few spare magazines (and a way to carry them around).
Sig Sauer’s MPX Essentials Kit gives you exactly that; with a specially-designed mag pouch and three (3) compact 20-round magazines that provide the perfect balance of firepower and maneuverability. Ideal for target shooting, cover shooting, and suppressor-friendly loadouts.
Featuring translucent polymer construction and reinforced feed lips, each magazine is secured with a special retention strap on the low-profile pouch.
Note: Generation 1 magazines will usually work in Generation 2 guns. But for optimal performance we strongly recommend purchasing the magazine that matches your gun. Just check an existing mag if you’re not sure (Black follower = Gen 1, Green follower = Gen 2).
