Considering all the unrestricted
interchangeable parts that can be shipped without an FFL; the P365 design is very flexible.
*Two grip frames: short 10 and XL
*Three Slides: one with X-Ray-3 sights, SAS with flush mount FT fiber-tritium, and XL with optic-ready
*Two Triggers: Curved or Flat
*Three Mag sizes 10, 12 or 15 round with flat base or pinkie base
Only restricted part that requires an FFL is the drop-in FCU that has the serial number.
The only thing I could hope for personally is an Optic-ready Short Slide with the optic cut in front of the X-Ray 3 rear sight to use them as lower 1/3 BUIS. Really, the optic negates any advantage of the longer slide's sight radius; and it would be a more concealable package.
Oh Well....That's the combo that Fabricated Arms is milling for me right now.
