SIG SAUER P220 .45 ACP 8-Round Magazine

SIG SAUER P220 .45 ACP 8-Round Factory Magazine

Equip a compatible P220 with a magazine made for its single-stack .45 ACP operating system. The SIG SAUER P220 8-round magazine is a factory replacement built for P220 pistols chambered in .45 ACP. Manufacturer part number MAG-220-45-8 and UPC 798681118205 identify this specific stainless-steel, eight-round configuration.

The P220 is known for combining a full-size service-pistol format with a single-column .45 ACP magazine. This replacement follows that dedicated layout instead of using a generic or multi-model body. It is a practical choice for adding range magazines, replacing a magazine that has been damaged or heavily worn, or keeping an additional factory-pattern spare with the pistol.

Correct Fit for the P220 Platform

This magazine is intended for SIG SAUER P220 pistols in .45 ACP. Its body dimensions, feed geometry, follower, and spring system are designed around that pistol and cartridge combination. Because SIG SAUER has produced several pistol families and caliber variants over time, buyers should verify the model and caliber markings on their firearm rather than selecting a magazine by appearance alone.

The eight-round capacity gives the magazine a standard P220 configuration suitable for routine range use and replacement service. The stainless-steel body provides strength and corrosion resistance, while the smooth silver-colored exterior makes this version easy to distinguish from blued magazine bodies in a mixed range bag.

Use and Maintenance

Extra magazines allow more time shooting and less time reloading between drills. They also make it easier to maintain separate training and reserve sets. Numbering magazines with a removable marker can help isolate one that causes repeated stoppages, while routine visual inspection can reveal bent feed lips, cracks, dents, or base-area damage before the next range session.

Keep the magazine reasonably clean and dry, and avoid applying excess oil where it can collect grit or contaminate ammunition. Follow the P220 owner’s manual when disassembling a magazine for cleaning. Before live fire, confirm that the unloaded magazine locks into the pistol and drops free as expected. Load only .45 ACP ammunition appropriate for the firearm, follow all manufacturer safety instructions, and observe applicable magazine-capacity laws.
