This replacement magazine is a factory original from Ruger. Designed to fit the Ruger SR45 Centerfire pistol.
Built to hold (10) rounds of ammunition. Will only hold .45 automatic colt pistol rounds. Constructed of blued steel to avoid corrosion and to surpass all the adversified torture test in it's way. This magazines also comes equipped with a hi-tensile compression steel spring to assure this magazine has minimal to no friction, and smooth feeding responses.
Keeping a few extra factory magazines around is never a bad idea; extra magazines save loading time at the range and also serve as a backup for those days when you simply cannot remember where you put your primary magazine.
