Description
The P365-RAINBOW 380 is a compact, optics-ready pistol chambered in .380 ACP, featuring a durable PVD rainbow finish. It’s built for shooters who prioritize a lightweight, reliable carry gun with a distinctive look. Since we started stocking this model in spring 2025, it has consistently been a top choice for repeat customers. The slide’s coating is notably resilient; our staff has noted it held up perfectly through multiple cleaning cycles with Hoppes No. 9.
Why This One?
- Optics-Ready Platform: The slide is cut for a Sig Sauer ROMEOZero footprint, allowing for easy red dot mounting without the need for an adapter plate.
- Proven Reliability: Built on the trusted P365 FCU (Fire Control Unit), this model delivers the same consistent performance the platform is known for, now in a softer-shooting .380 ACP format.
- Ultra-Lightweight Build: With a measured weight of just 5.8 ounces, this pistol disappears in a holster, making it an excellent choice for all-day, comfortable carry.
- Durable PVD Finish: The vibrant rainbow finish is more than cosmetic. It’s a Physical Vapor Deposition coating that provides excellent corrosion resistance and has proven tough against solvents and wear in our handling.
- Complete Package: Comes with one 10-round magazine and all necessary paperwork, ready for your FFL transfer upon purchase.

Q & A
Does this come with iron sights installed?
No, the slide is optics-ready and does not come with iron sights pre-installed. The cut is for a Sig Sauer ROMEOZero red dot footprint. You can mount a compatible optic directly, or aftermarket iron sights can be installed by a qualified gunsmith.
Is the rainbow finish just for looks, or is it durable?
The PVD (Physical Vapor Deposition) finish provides functional durability alongside its distinctive appearance. It offers strong corrosion resistance. In our shop, the finish has shown excellent resilience, handling multiple cleanings with common solvents like Hoppes No. 9 without any degradation in the coating’s integrity or color.
What is included in the box?
