This is the factory Taurus TX22 .22 LR 22-round extended magazine. 

Don’t settle for fewer rounds when you can have a 22+1 capacity, thanks to this genuine Taurus magazine!

The polymer body and extension provide a lightweight yet durable ammo delivery system that is kept running smoothly by a high-quality steel spring and polymer follower. 

With the side-facing channels and button, you can load with ease and never lose track of your remaining rounds. The Taurus TX22 is a great training pistol, so the additional rounds provided by the extension will provide a ton of value. 

We don’t know how long these will be in stock, so grab a few while you can!
