The Sig Sauer 1911 X 8-round magazine in .45 Auto is a reliable, no-nonsense steel magazine built for full-size 1911 X pistols. This is OEM Sig hardware—the right fit for shooters who want to trust their ammunition supply without guessing or second-guessing. Whether you're running drills at the range, training for defensive readiness, or just keeping spares on hand, a quality magazine is foundational gear.
Built from steel with a polymer baseplate, this magazine handles the recoil impulse and feeding demands of .45 Auto without drama. The side witness holes let you glance down and confirm your round count without breaking your grip or unloading—a small feature that saves time and mental load when you're cycling through magazines on a busy range or in training.
Eight rounds is the standard capacity for a single-stack 1911 platform, giving you a practical balance between control and firepower. The black oxide finish resists rust and blends with your pistol's aesthetics. If you own a Sig Sauer 1911 X, having at least two or three quality magazines in the rotation is smart practice—it gives you fast reload options and lets you maintain each mag without stress.
