Description
The P365 changed the concealed carry world when it packed 10+1 rounds into a truly pocketable frame, and the P365-380 brings that same formula to folks who want less recoil in their hands. Chambered in .380 ACP, this version shoots noticeably softer than its 9mm sibling and takes less effort to rack, which makes a real difference for anyone with smaller hands, reduced grip strength, or just a preference for a gun that is pleasant to practice with. This model adds an ambidextrous manual thumb safety for those who want that extra layer of deliberate control in their carry routine.
Why the P365-380 Works So Well for Everyday Carry
At 15.7 ounces with a 3.1 inch carbon steel barrel and a 5.8 inch overall length, this pistol disappears under a t-shirt without giving up a usable grip or real sights. And these are real sights: SIGLITE night sights come standard, so you get a glowing sight picture in low light instead of the plastic bumps a lot of micro pistols ship with. The slide is cut for optics too, accepting the ROMEOZero Elite or any red dot sharing that RMSc-style footprint, and the dovetailed irons let you set up a co-witness in the right configuration. The Nitron-finished stainless steel slide and redesigned two-piece captured guide rod are built to hold up to serious round counts.
One Platform, Endless Support
Here is the part that makes this pistol such an easy choice: it shares its grip module and fire control unit with the standard 9mm P365. That means it drops into the same massive ecosystem of holsters, flat triggers, XSeries grip modules, FOXTROT lights, and just about every other P365 accessory on the market. You are not buying into an orphan platform.
What Ships With the Sig P365-380
Sig includes two 10-round steel magazines, one flush-fit for maximum concealment and one extended for a full-hand grip at the range. Whether this is a first carry gun, a step down in recoil from a 9mm, or simply a pistol you will train with more because it is comfortable to shoot, the P365-380 earns its spot in the lineup.

Frequently Asked Questions
Will the P365-380 fit in my existing P365 holsters?
Yes. The P365-380 uses the same grip module and overall dimensions as the standard 9mm P365, so it fits all existing P365 holsters. It also works with the same accessory ecosystem, including XSeries grip modules, flat triggers, and FOXTROT lights.
What red dot optics fit the Sig P365-380?
The slide is cut for the Sig ROMEOZero Elite and any micro red dot that shares that RMSc-style footprint, such as the Shield RMSc or Holosun 507K with the right plate setup. The dovetailed front and rear night sights can also give you a co-witness in the proper configuration.
Is the P365-380 easier to shoot than the 9mm P365?
That is the whole point of this model. The .380 ACP chambering produces noticeably lighter recoil, and the lightened slide takes less force to rack. It is a great fit for people with smaller hands, less grip strength, or anyone who finds a 9mm micro-compact snappy to shoot.
Does this P365-380 model have a manual safety?
Yes, this specific version (MPN 365-380-BSS-MS) includes an ambidextrous manual thumb safety, which is what the MS in the part number stands for. Sig also makes a version without one, so double-check the part number if you have a preference either way.
