My county only allows TWO handguns (by serial number) on a CCW permit. So being able to turn an edc 365XL with 507K into a 365 ankle/pocket gun as needed is a real world advantage.
For the 320 might be nice to swap grips for glove vs summer weather.
This is the only reason I’m switching from G48 & G19 to P365XL & P320.
