This replacement magazine is a factory original from Smith & Wesson. Designed to fit the Smith & Wesson M&P compact pistol.
Built to hold (8) rounds of ammunition. Will only hold 45 automatic colt pistol rounds. Constructed of stainless steel to avoid corrosion and to surpass all the adversified torture test in it's way. This magazine 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.
