SIG SAUER 1911-X .45 ACP 8-Round Magazine

SIG SAUER 1911-X .45 ACP 8-Round Steel Magazine

This eight-round magazine is made for full-size SIG SAUER 1911-X pistols chambered in .45 ACP. Produced by MEC-GAR and listed under SIG SAUER part number 8901701, it combines a traditional single-stack 1911 format with a durable black steel body. It is a practical factory-specification choice for replacing a worn magazine, adding a spare to a range kit, or keeping multiple magazines prepared for training.

Full-Size 1911-X Fit

Magazine compatibility matters on any semiautomatic pistol, and the 1911 platform is no exception. This model is identified specifically for full-size 1911-X pistols in .45 ACP. Its single-stack configuration and eight-round capacity match the intended application, helping maintain the fit and cartridge presentation geometry expected by the pistol. Confirm the firearm model and caliber before ordering; this is not a universal magazine for every 1911 size or chambering.

Steel Construction and Capacity Checks

The steel body is designed for the repeated insertion, removal, and loading cycles associated with routine practice and carry preparation. A black finish gives the magazine a subdued appearance, while side witness holes provide a quick visual reference for loaded capacity. The eight-round format offers a familiar balance for full-size .45 ACP 1911 pistols and makes it easy to organize consistent strings during drills or range sessions.

Why Keep a Spare Magazine?

Magazines are working components and can experience wear, contamination, or damage over time. Having a known, model-correct spare allows a shooter to compare function when diagnosing a feeding issue. It also reduces downtime at the range by allowing several magazines to be loaded before a course of fire. Marking individual magazines with a removable identifier can help track performance without altering the pistol.

Maintenance and Safe Use

Keep the magazine clean and dry, and inspect the body, feed lips, follower, and base area periodically. Dirt, deformation, or a weakened internal spring can affect feeding even when the pistol itself is in good condition. Load only serviceable .45 ACP ammunition, follow the firearm manufacturer’s instructions, and comply with all applicable magazine-capacity laws.
