Sig Sauer Magazine 9MM 10 Rounds Extended Base Plate Fits Sig P211 P320 Steel Black 8902289 UPC 798681752461
Product Description
The Sig Sauer Factory 10-Round 9mm Magazine with Extended Baseplate (8902289) is a genuine OEM replacement magazine engineered for Sig Sauer P211 and P320 subcompact and compact 9mm pistol configurations. Manufactured to Sig Sauer's strict defense-grade specifications, this 10-round compliant magazine combines high-tensile internal spring geometry with an ergonomic extended floorplate to deliver maximum firing grip control and zero-fail feeding performance.
Constructed from heavy-gauge stainless steel with a high-friction black anti-corrosion coating, the 8902289 features precision-punched visual witness holes along the rear spine for quick round verification. The extended baseplate adds critical pinky support for shooters with larger hands or those seeking improved recoil management on compact frame models without altering the 10-round capacity mandate.
Equipped with a lubricious, anti-tilt polymer follower and a heavy-duty steel wire spring, this factory magazine ensures smooth cartridge elevation into the chamber and reliable slide lock-back after the final shot. Whether needed for state-compliant concealed carry, home defense, or spare range training, Sig Sauer factory magazines deliver uncompromised reliability in critical moments.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Sig Sauer P211 and P320 subcompact/compact 9mm frames (Note: Designed with the extended floorplate footprint; will not seat in full-size or X-Large grip modules without baseplate adjustments).
- Perform a complete firearm safety check: drop the existing magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Inspect the new magazine feed lips, follower tension, and extended baseplate seating prior to loading.
- Load up to 10 rounds of 9mm ammunition into the magazine, tapping the rear spine gently against your palm to seat cartridges against the back wall.
- Insert the magazine firmly into the pistol grip cavity until the magazine catch locks with an audible click.
- Depress the magazine release button to verify smooth, drop-free operation under gravity when empty or loaded.
