Month or two Magguts released their +2 kit for the extended xl mags for the p365.
I got one, by my fault ordered the standard and had to swap it with them for the extended floor plate.
The standard will not fit the xl frame.
All is well now.
Finally got around to shooting it some today.
Put a box through. No problems.
Adds very little to the length of the grip.
Now the p365x / xl has 14+1 capacity.
