Sig Sauer builds this factory magazine (part no. MAG-MOD-F-9-17-COY) for the P320, M17, and M18, holding 17 rounds of 9mm Luger in a black and coyote two-tone steel body that matches the military-contract M17/M18 color scheme. Since the M17 and M18 are the U.S. military’s adopted variants of the commercial P320, magazines are shared across all three, giving owners a common spare-parts pool whether they run a commercial or military-pattern pistol. Manufactured to Sig’s own factory tolerances, it seats and feeds exactly as intended. For Sig Sauer P320, M17, and M18 owners, this handgun magazine is a dependable factory-correct spare.
