Product Description
The Ruger Mark III (MK3) 10-round magazine is the factory-standard steel magazine for one of the most popular rimfire pistols in the world. It is important to note that there are two distinct variations: the Standard MK3 and the MK3 22/45. They are generally not interchangeable due to their different floorplate designs.

| Caliber | .22 Long Rifle |
