Sig Sauer P365-380 Micro-Compact, .380 ACP, 3.1 in, 2x10rd

Description

The Sig Sauer P365-380 Micro-Compact, .380 ACP, 3.1 in, 2x10rd is a purpose-built concealed carry pistol that shrinks the proven P365 platform into an even lighter, lower-recoil package. Chambered in .380 ACP, it pairs a 3.1-inch Nitron-finished barrel with a modular polymer grip and ships with two 10-round magazines. Factory night sights and an optic-ready slide make it ready for low-light or dot-equipped carry right out of the box. Per Sig Sauer specs, this model weighs just 15.7 ounces unloaded, making it one of the lightest micro-compacts in its class. Last updated: April 2026.

Key Features

• Optic-Ready Slide — Why it matters: You can mount a red dot without sending the slide to a machinist, cutting setup time and cost for a faster sight picture.
• Factory Night Sights — Why it matters: Tritium inserts let you acquire your sights in total darkness, which is critical for a carry gun that might be used at night.
• Two 10-Round Magazines — Why it matters: You get a spare mag out of the box, doubling your capacity to 20 rounds without an extra purchase.
• .380 ACP Chambering — Why it matters: Lower recoil than 9mm means faster follow-up shots and easier control for shooters with smaller hands or reduced hand strength.
• Modular Polymer Grip — Why it matters: You can swap grip modules to change texture, size, or color without buying a whole new gun, letting you tailor the fit to your hand.

Who It’s For

This pistol is built for daily concealed carriers who prioritize lightweight, low-recoil performance. It suits new shooters transitioning from .22 to a defensive caliber, experienced carriers wanting a backup or summer gun, and anyone who prefers .380 ACP for its manageable snap. If you carry in shorts and a t-shirt or need a deep-concealment option, the P365-380’s 15.7-ounce weight and 3.1-inch barrel make it disappear under light clothing.

Pros & Cons

• Pro: Extremely lightweight (15.7 oz unloaded) — easy to carry all day without fatigue.
• Pro: Optic-ready from the factory — saves you $50-100 in milling costs.
• Pro: Factory night sights included — no immediate upgrade needed.
• Con: .380 ACP has less terminal performance than 9mm at longer ranges — stick to defensive loads designed for short barrels.

FAQ

Is the P365-380 compatible with standard P365 holsters?

Yes, most P365 holsters will fit the P365-380 because the external dimensions are nearly identical. However, confirm with the holster maker that the .380 model’s slide profile matches your holster’s retention system.

Can I use +P ammunition in this pistol?

Sig Sauer does not recommend +P .380 ACP ammunition in the P365-380. Stick to standard-pressure loads to avoid excessive wear and potential reliability issues. Per Sig Sauer specs, the barrel is rated for standard-pressure ammunition only.

Does the P365-380 come with a manual safety?

No, the standard P365-380 ships without a manual safety. Some SKUs include one, so check your specific model. The trigger safety and striker block are the only passive safeties.

What red dots fit the P365-380 slide?

The optic cut is designed for the Sig Sauer ROMEOZero, but it also accepts the Holosun 407K/507K and other micro red dots with the same footprint (RMSc pattern).
