Sig Sauer MAGMODF921 P320/P250 9mm Luger 21-Rd Extended Blued Steel Magazine

The Sig Sauer MAGMODF921 is a factory extended 21-round magazine built for 9mm Luger chambering in the Sig Sauer P320 full-size pistol, the P320 X-Five, and the legacy P250 line. Engineered as an OEM replacement or spare, this extended magazine adds four additional rounds over the standard full-size capacity, giving competition shooters, range users, and duty pistol carriers a meaningful boost in on-board firepower.
