This fits the SIG P365 factory 10 round magazine, designed to give you the same amount of grip the factory 12 round magazine would give, but without the 12 rounds, for those not able to get that magazine.
Now with 'Comfort Edge' - a slightly larger radius on the edge for a more comforable concealment.
See the Small
Extended Base Pad to add the right amount of pinky room.
Don't like the extension, get a Flush Base Pad
Note: The does not extend the 10 round magazines capacity.
