SIG SAUER P211/P320 9mm 23-Round Magazine

SIG SAUER P211/P320 23-Round 9mm Magazine

This factory SIG SAUER extended magazine provides a 23-round capacity for compatible 9mm P211 and P320 pistols. Manufacturer part number 8901964 uses a black steel body and an extended base assembly, giving owners a high-capacity factory option for range sessions, training, and compatible duty-size configurations.

Factory Magazine for Compatible SIG Pistols

The magazine is identified for SIG SAUER P211 pistols and compatible full-size or carry-size P320 configurations. Its 23-round capacity extends below the grip, so it is intended for applications where additional ammunition capacity is preferred over a flush-fitting profile. P320 grip modules are available in multiple sizes and generations; compare the pistol model, caliber, and grip-module configuration with this listing before ordering.

Steel Body and Extended Format

A steel magazine tube supplies the rigidity needed to maintain feed-lip geometry and guide the follower through its full travel. The black finish gives the magazine a subdued appearance, while the extended base provides the space required for its 23-round capacity. Visible witness holes allow a quick indication of the ammunition remaining without disassembling the magazine. As a factory SIG SAUER component, it is built around the intended magazine-catch and feed geometry of the specified platforms.

Range, Training, and Replacement Use

A higher-capacity magazine can reduce interruptions during range drills and longer practice strings. It can also serve as a factory replacement or spare for owners whose pistol and local regulations support this capacity. Numbering or otherwise marking individual magazines can help track performance and identify a unit that needs inspection after hard use.

Care and Compatibility Check

Keep the magazine free of dirt, lint, excessive lubricant, and damaged ammunition. Periodically inspect the feed lips, follower, spring movement, witness holes, base assembly, and magazine-catch opening. Follow the firearm owner’s manual for unloading, cleaning, and function checks. Confirm the firearm is unloaded before checking magazine fit, and do not force a magazine that does not seat or release normally.

Magazine-capacity and transfer restrictions vary by jurisdiction. Verify that a 23-round magazine is legal for purchase, possession, and use in your location before ordering.
