This is the Tyrant CNC Sig P320, P250 +5 magazine extension. 

Instantly increase your Sig P320 capacity by five rounds with this high-quality magazine extension from Tyrant CNC. 

Precision machined from aerospace-grade aluminum, they are incredibly durable and, let’s be honest, some of the best-looking extensions on the market! The additional weight will cause your magazine to drop quicker and allow you to reload even faster. 

A new power spring is included and no tools are required for installation, so you can have a completely upgraded magazine within seconds. Did we mention it’s made in America? What more can you ask for?

*Compatibility notes: the magazine extension works with the 15 and 17-round factory magazines but not the 10, 12, or 21-round factory magazines.

Add a couple of mag extensions to your cart and upgrade your magazines ASAP!
