Factory 8-Round Magazine for the SIG SAUER P239
This SIG SAUER P239 magazine is a factory replacement or spare magazine for P239 pistols chambered in 9mm Luger. It holds eight rounds in the compact single-stack format associated with the 9mm P239 and is identified by manufacturer part number MAG23998 and UPC 798681111237.
A dedicated magazine is an important part of maintaining a reliable range or defensive setup. Keeping multiple magazines available allows a shooter to separate training magazines from carry equipment, replace a damaged or worn magazine, or spend more time practicing before stopping to reload individual magazines.
Purpose-Built P239 Compatibility
This magazine is designed specifically for the SIG SAUER P239 in 9mm Luger. The P239 was offered in multiple chamberings, so matching both the pistol model and caliber is essential. This eight-round version is for the 9mm pistol and should not be confused with magazines intended for .357 SIG or .40 S&W P239 variants.
SIG SAUER identifies the magazine as a single-stack design sized for the subcompact P239 platform. Side witness holes help the user check the approximate loaded condition without unloading the magazine. The compact body is intended to fit the P239 grip without converting the pistol to a different magazine pattern.

- Eight-round capacity: Provides the standard compact capacity for the 9mm P239.
- 9mm Luger compatibility: Intended only for P239 pistols chambered in 9mm.
- Single-stack configuration: Matches the slim magazine well of the P239 platform.
- Steel construction: Provides a durable body for repeated insertion, loading, and range use.

Range and Maintenance Use
Magazine-related problems can result from accumulated debris, worn springs, damaged feed lips, or a compromised follower. Each magazine should be inspected regularly, especially after being dropped during reload drills. Keep the body and follower clean and dry, and follow SIG SAUER’s guidance before disassembling the magazine for maintenance.
When loading, use only the correct 9mm Luger ammunition and do not force additional cartridges beyond the listed eight-round capacity. Before relying on any new magazine, verify fit, insertion, retention, feeding, slide-lock operation, and release in the specific unloaded pistol under safe range conditions.
