This is the ProMag Taurus PT92, PT99 9mm 20-round magazine. 

Upgrade the capacity of your Taurus PT92 or PT99 with this 20-round extended magazine from ProMag! 

High-quality and affordable don’t typically go hand in hand, but in this case, they do. A heat-treated steel tube houses a chrome silicon wire spring and an injection-molded polymer follower, delivering superior durability and reliability. 

And if anything ever goes wrong with them, they are backed by a lifetime replacement warranty! Whether your PT92/PT99 is used for competition, home defense, or plain old fun at the range, these 20-round extended magazines are sure to please. 

Why not pick up a few extended magazines and stay prepared for anything?!
