Short answer: Match the slide length and the grip. A P365XL barrel is not a standard P365 barrel. The flat trigger shoe is listed for any P365 fire control unit. Magwells and recoil kits follow the model in the title.

Trigger and mag release: The True Precision flat trigger is a shoe. The listing says it fits any Sig P365 fire control unit. The extended mag release is titled Sig P365. That listing does not name XL, Macro, or Fuse.

Sights: Night Fision 507K-height tritium sights are titled for the P365 and fit a P-Series dovetail. That is an iron sight, not the optic cut. TruGlo TFX Pro is titled Sig P365 and combines tritium and fiber. Optic-ready P365 slides sit in the K/RMSc family: red dot footprints. Tritium vs fiber.

Barrel and comp: The threaded barrel in stock is titled P365XL. The listing says it fits the P365XL and does not print a thread pitch. The True Precision True-Lock comp is listed for P365, X, XL, and Macro with a 1/2x28 threaded barrel. Radian Ramjet is a barrel and comp together, sold as a P365 3.1 and a P365XL 3.7: Ramjet fit guide. Slide length is the same split as magazines: does a P365 mag fit an XL?

Grip and spring: The True Precision magwell title says Fuse. The listing says Fuse and XMacro, not the standard P365 grip. The 3.1 recoil kit is the short P365. The 3.7 and 4.3 kits are separate: P365 recoil spring guide. Holsters have to clear a comp or a light: P365 holsters.
