SIG SAUER P365-380 Rainbow Manual-Safety Pistol

The SIG SAUER P365-380 Rainbow brings the compact P365 format to the softer-shooting .380 ACP cartridge while adding a distinctive multicolor slide treatment. This exact manual-safety model is identified by manufacturer part number 365-380-RBT-MS and UPC 798681671618. It features a 3.1-inch barrel, striker-fired operation, an optic-ready slide, XRAY3 day/night sights, and two 10-round steel magazines.

Compact .380 ACP Configuration

The P365-380 retains the familiar proportions and control layout of the P365 family while being chambered for .380 ACP. Its short barrel and compact grip make the pistol easy to transport and convenient to fit into a purpose-built storage or carry setup. The modified polymer grip provides a textured surface, while slide serrations offer defined grasping areas for loading and chamber checks.

The .380 ACP chambering may appeal to shooters seeking a compact pistol with a different recoil character than comparable 9mm models. Ammunition performance, reliability, and point of impact can vary by load, so owners should test their selected ammunition with the pistol before depending on it for any serious purpose.

Rainbow and Black Finish

This model uses a rainbow-finish slide paired with black components for a high-contrast appearance. The multicolor surface can look different as lighting and viewing angles change, making each view more visually distinctive than a standard black pistol. The cosmetic treatment does not change the basic operating layout of the P365-380.

Finish care should follow SIG SAUER’s instructions. Avoid abrasive materials or harsh chemicals unless the manufacturer specifically approves them. Wipe down exterior surfaces after handling, keep the pistol unloaded during cleaning, and use the recommended lubrication points to protect function without unnecessarily affecting the finish.

Manual Safety and Handling

This exact variant includes an external manual safety. That feature is part of the model identity and separates it from P365-380 configurations without the control. Training should include disengaging the safety during presentation, re-engaging it when appropriate, and maintaining consistent trigger-finger discipline throughout loading, unloading, and holstering.

A compatible holster should fit the P365-380, fully cover the trigger guard, accommodate the safety levers, and allow for any optic added to the slide. The manual safety is an additional user-operated control; it does not replace secure storage, safe direction, or familiarity with the owner’s manual.

Optic-Ready Slide and XRAY3 Sights

The serrated slide is factory prepared for a compact reflex sight. Optic dimensions, mounting screws, and installation procedures vary, so confirm exact compatibility with the optic manufacturer before installation. After fitting an optic, verify mounting security, function, and zero at the range.

XRAY3 day/night sights provide a complete factory sighting system when no optic is installed. Their visible daytime layout and luminous elements are designed to give the shooter a useful sight reference across changing light conditions.

Magazine Package

SIG SAUER supplies two 10-round steel magazines with this model. The listed capacity is 10 rounds in the magazine plus one in the chamber when loaded according to the manufacturer’s instructions. A second magazine supports range practice, reload drills, or regular magazine rotation.

Inspect both magazines regularly for damage, contamination, or weakened components, and keep them clean according to SIG SAUER guidance. Function-test each magazine with the ammunition selected for practice or lawful carry, since dependable feeding is a system-level result involving the pistol, magazine, and cartridge together.
