P320 Extended Magazine Release


The Grayguns P320 Extended Magazine Release is a drop-in aftermarket upgrade for SIG Sauer® P320 Standard, X-Series and TXG modules*. The reversible release is manufactured in the United States from tool steel and is properly heat treated for maximum durability and wear resistance.

Along with the extension to make the release more accessible, it features a checkered face and improved ergonomics.

Available in our standard Diamond Like Carbon (DLC) black finish.

Occasionally, you’ll see additional finishes available in Titanium nitride (TiN) Gold, Physical Vapor Deposition (PVD) Blue or PVD Coyote.

Installation requires both the OEM Magazine Catch Stop and Magazine Catch Spring as they are not included.



  • Properly heat-treated tool steel
  • Longer than OEM version
  • Improved ergonomics
  • Checkered face
  • Reversible design for right and left-handed shooters

Fit Guide

Fits all P320 Standard, X-Series and TXG modules. *This mag release will not fit the AXG modules as the AXG grip has a different design.

Installation requires OEM Magazine Catch Stop and Magazine Catch Spring.

Discoloration in the mid-section of the part is normal. It can not be seen when installed and does not affect performance. The discoloration is the result of fixture “pinch points” holding the part during the coating process.
