Description
Here at Indiana Gunshop, we’ve had the P365-RAINBOW 380 on our shelves since January 2026, and it’s been a solid mover. Low return rate — customers generally get exactly what they expect from this product. This is a slim, optics-ready 380 ACP carry piece that gives you the proven P365 platform in a lighter-recoiling caliber. Staff note: ‘Had a customer drive 3 hours to pick this up instead of waiting for shipping. That says something.’ It’s for anyone who wants a reliable pocket pistol with a unique look.
Key Highlights
- Rainbow Titanium Nitride Finish: Distinctive, corrosion-resistant slide coating that stands out from the usual black or FDE.
- Optics Ready Slide: Cut for the RMSc footprint — mount your preferred micro red dot without additional milling.
- 380 ACP Chambering: Lower recoil than 9mm, making it ideal for new shooters or those with hand strength issues, while still offering 10+1 capacity.
- True P365 Grip Angle: Same ergonomics and pointability as the 9mm version, with a 10-round flush-fit magazine.
- Flat Trigger: Crisp, short reset trigger that helps with accuracy in rapid fire.

What Buyers Ask
Does this use the same holsters as the 9mm P365?
Yes — the P365-RAINBOW 380 has the same external dimensions as the standard P365 9mm, so any holster molded for the P365 9mm will work.
Can I use standard P365 magazines in this?
No — the 380 version uses its own specific magazines because of the different feed geometry. It comes with one 10-round flush-fit mag.
Is the finish as durable as a standard PVD coating?
Rainbow TiN is a PVD coating — it’s hard, corrosion-resistant, and holds up well with normal carry wear. It will show holster wear over time, but that’s true of any finish.
