Sig Sauer P320/P250 Full Size Magazine - .40 S&W/.357 Sig, Steel Matte Finish
A Sig Sauer P320/P250 full size magazine in .40 S&W/.357 Sig is a factory-original accessory that belongs in every P320 or P250 owner's kit. Whether you're building out a duty loadout, stocking spares for the range, or keeping backups for carry, genuine Sig magazines are engineered to the same tolerances as your pistol—they feed reliably and cycle consistently, without the feeding hiccups or reliability questions that come with off-brand alternatives. If your Sig ever shows hesitation feeding or cycling, swapping in a factory magazine is often the quickest diagnostic step before assuming anything else is wrong.
This full size magazine ships with Sig's hardened steel body, finished in matte to resist corrosion and wear through years of use. The removable base plate lets you take it apart for cleaning, and the black polymer follower sits inside, guiding rounds smoothly into the mag well. Whether you're running this at the local range, in a defensive context, or for hunting where reliability matters, you're working with the same magazine your P320 or P250 was born to use.
Build redundancy into your carry or range setup with a spare or two. Factory magazines are the foundation of a trustworthy defensive or duty pistol—they're inexpensive insurance against the one thing you don't want to happen when you need your gun to work.
