This is the ProMag Smith & Wesson M&P 22 Compact .22LR 10-round magazine. 

Even your rimfire rounds deserve an extremely durable magazine, and this one from ProMag is one of the toughest!

The heat-treated steel body features a black oxide finish that delivers superior corrosion and scratch-resistance. At the same time, the chrome silicon wire spring is designed to last repeated and constant pressure. 

Side-facing load-assist tabs make reloading a breeze, and the tracks double as witness windows. An impact-resistant polymer follower and floorplate finish off the magazine—what else is there to ask for?!
