PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Warne built this magazine extension for the Sig Sauer P320 to give you a clean +3 capacity boost, better magazine handling, and a more useful base pad for reloads. This black extension is designed for 9mm P320 factory magazines and gives you extra rounds without turning your setup into a goofy oversized brick.
Fitment
Fits Sig Sauer P320 9mm 17-round factory magazines.
Does NOT fit
Does not fit every P320 magazine blindly. Verify you are using a compatible factory Sig Sauer P320 9mm 17-round magazine before ordering. This is not a universal handgun mag extension.
What it does
This extension adds 3 rounds to compatible Sig Sauer P320 9mm magazines while also giving the magazine a larger, more ergonomic base for better insertion and easier stripping if needed.
Why it’s worth it
If you want more capacity and a better magazine footprint without overcomplicating things, this is a clean upgrade. More rounds are useful. Better handling is useful. Nice when a part actually earns its keep.
