This is the ProMag Ruger MAX-9 9mm 10-round magazine.

If you’re in need of a compliant magazine for your Ruger MAX-9, look no further!

You will never have to worry about durability or reliability with this magazine, thanks to its heat-treated steel construction and injection-molded polymer follower. On top of it all, you’ll find a black oxide finish covering the entire body, providing superior corrosion resistance.
