SIG SAUER | MPX Gen 2 Magazine | 9mm | Black

SIG builds the MPX magazine from a metal‑and‑polymer hybrid design -⁠- metal feed lips for genuine long‑term durability, a lightweight polymer body that holds its shape under recoil -⁠- the result of a two‑year design project specifically to meet SIG's own reliability standard rather than a quick adaptation. Available in 10, 20, 30, and 35‑round capacities in 9mm, all supporting the MPX's last‑round‑hold‑open function and compatible across every MPX generation. The factory magazine built to the exact tolerances the platform's engineers actually specified.
