P320 Extended Magazine Release Fit Guide
The extended magazine release fits the following grip modules
- SIG Sauer’s P320 Standard, X-Series, and TXG modules
- Grayguns’ Laser Sculpted X-Series, Laser Checkered X-Series, and TXG modules
- Wilson Combat Grip Modules sold by Grayguns
We have not tested our extended magazine releases in third-party grip modules other than those sold by Grayguns. We can not tell if or how they will fit in other grip modules, especially the aluminum modules on the market. In short, due to variations in design, they may not fit third-party grip modules.
Important Notes*
- This magazine release will not fit the AXG modules as the AXG grip has a different design
- It will not work with grip modules for .45 caliber P320s
Installation requires OEM Magazine Catch Stop and Magazine Catch Spring.
Discoloration in the mid-section of the part is expected. However, it can not be seen when installed and does not affect performance. The discoloration results from fixture “pinch points” holding the part during the coating process.

Disclaimer
Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.
Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.
Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.
Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.





In my opinion, it is made extremely well and does exactly what I wanted it to do easy install would be better if it came with the spring, but not a dealbreaker
I have a Sage Dynamics/Agency Arms P320 that utilizes an Icarus aluminum grip module, which is thicker than most other grip modules.
The stock Sig mag release just doesn’t stick out far enough.
This GG extended mag release not only sticks out further, without sticking out too far, it also has a much better texture, similar to what comes on the AXG grip module.
Additionally it’s milled out of a solid block of steel, unlike the stock MIM part, and is a nice deep black, instead of the weird brownish color of the stock part.
A welcome addition to what was already my favorite pistol, well worth the money.
Awesome upgrade I wish it came with the spring only downside but still great
Great product! Better than oem. Perfect size for me
Fixed my issue where OEM release was too short to hit without shifting my grip. Was a bit sharp on my thumb, but with a small bit of filing, I took the hard edge off. If I had any suggestions, I’d say taking the edges off the sides of this release would be an excellent improvement. As for me, it works just fine, and is an excellent upgrade for my P320.
