SIG SAUER 1911 9mm 8-Round Magazine

SIG SAUER 1911 9mm 8-Round Magazine

This factory SIG SAUER magazine is designed for compatible full-size 1911 pistols chambered in 9mm Luger. It carries eight rounds in a single-stack stainless-steel body and is identified by manufacturer part number MAG-1911-9-8, also cataloged as MAG191198, with UPC 798681539451. It is suitable as a replacement for an original magazine or as an additional factory spare for range, training, or lawful defensive use.

The magazine follows the traditional slim, single-stack 1911 format. Its dimensions and feed geometry are designed around SIG SAUER’s full-size 9mm 1911 platform, helping maintain the intended relationship between the magazine, frame, magazine catch, feed ramp, and slide stop.

Stainless-Steel Construction

SIG manufactures the magazine body from stainless steel and gives it a matching stainless finish. Stainless construction provides strength and corrosion resistance while allowing the feed lips to retain the precise shape required for dependable cartridge presentation. The steel baseplate protects the bottom of the body and maintains the magazine’s traditional low-profile appearance.

Side witness holes provide a convenient visual reference for the loaded-round count. The follower and spring are factory-matched to the eight-round body, supporting consistent upward pressure as cartridges are fed. One magazine is included.

Full-Size 1911 Fit

SIG lists this magazine for its full-size 1911 pistols in 9mm Luger. It is not intended for .45 ACP, .38 Super, or other chamberings, and it should not be assumed to fit shortened Officer-size frames. Although many 1911 components appear similar, magazine-body length, feed-lip geometry, baseplate shape, and frame tolerances can vary between manufacturers and models.

Before live use, verify that the unloaded magazine inserts fully, locks securely, drops free as intended, and activates the slide stop correctly in the specific pistol. Owners using aftermarket magwells, grips, or frame components should confirm clearance with the manufacturer of those parts.

Factory Replacement for Consistent Fit

A reliable magazine is essential to the operation of any semi-automatic pistol. Choosing a factory SIG SAUER magazine helps preserve the dimensions, spring rate, follower travel, and catch engagement intended for the pistol. It also makes this model a useful choice for replacing a worn magazine or keeping separate magazines for training and defensive ammunition.

Inspect the magazine regularly for dents, damaged feed lips, corrosion, a cracked follower, weak spring tension, or a loose baseplate. Clean it according to SIG SAUER guidance without leaving excess lubricant inside the body, since oil can collect dirt and residue. Use only the correct 9mm ammunition and observe all applicable magazine-capacity, possession, and shipping restrictions.
