Glock Model

We designed this Glock magazine extended base plate for a simple reason: every shooter, no matter what your use case is, needs more rounds than a stock mag provides.

If you find yourself in a shootout, every moment spent reloading is a moment your enemy has an advantage. When you’re running a course in a competitive shooting competition, swapping mags wastes valuable seconds. Even if you’re just practicing hitting targets at the range, reloading is a waste of time.

That’s why you need our Glock magazine extension for sale. It fits five more rounds to your Glock’s mag. That’s five more shots at the range, in a competition, or when defending your life.

A Glock Magazine Extended Base Plate for the Boys in Blue

Our Glock mag extension isn’t just functional. We’ve engraved the Thin Blue Line flag on the base. With this Glock base plate, you show your support for the men and women who put their lives on the line for our community every single day.

Here’s what makes our Glock magazine extended base plate truly industry-leading quality:

  • Aircraft-grade aluminum with cerakote coating
  • Added 1.2oz weight for rapid mag ejection
  • Ergonomic extension for grip
  • 100% USA-machined parts
  • Custom 0.051” Rocket Wire to ASTM A228 spring with extra coils and retainer spring for select models
  • CNC-milled engraving that lasts for years

Base plates are designed for specific models. Check model compatibility before ordering.
