If you shoot a Ruger Mark III 22/45, you know that reliable magazines are as important as the pistol itself. The Mec-Gar 10-round steel blue magazine for Ruger Mark III 22/45 .22LR gives you a dependable, well-built alternative to factory mags—the kind of spare that serious .22 shooters keep on hand for range days, competition, or plinking sessions. Mec-Gar has built a reputation manufacturing OEM magazines for major firearms makers, and this magazine brings that same engineering to the aftermarket.
Built from heat-treated carbon steel with a blued finish, this magazine is made to last. The high-tensile music wire spring ensures consistent feeding cycle after cycle, and the polymer follower and flush-fit floorplate are engineered to work smoothly with your Mark III's design. Ten rounds gives you a practical capacity for most shooting scenarios without excessive bulk.
Whether you're stocking up on spares, replacing a worn mag, or just want the peace of mind that comes with a quality backup, this Mec-Gar magazine delivers the reliability you'd expect from a brand that supplies to the firearms industry. It's the kind of thing you buy once and never think about again—until you're glad you have it.
