Description
The P365 changed what people expect from a carry pistol, and this version takes that proven platform and makes it softer to shoot and easier to handle. Chambered in .380 ACP, the P365-380 keeps the same grip module and fire control unit as the 9mm version but uses a lightened slide and barrel, which translates to noticeably less recoil and an easier slide to rack. For anyone with reduced hand strength, or who just prefers a gentler shooting experience without giving up capacity or quality, this one makes a lot of sense. And the Robin's Egg Blue grip module with the stainless slide and nickel-finished controls gives it a look you will not find on the average gun counter.
What the P365-380 Robin's Egg Blue Brings to the Table
You get a 3.1 inch barrel, a 5.8 inch overall length, and a weight of just 15.7 ounces with the magazine in, so it disappears under a t-shirt without a fuss. Sig includes XRAY3 day/night sights that glow in low light and pick up fast in daylight, plus a frame-mounted manual safety for anyone who wants that extra step in their carry routine. The slide wears front and rear serrations and comes with a removable sight plate cut for RomeoZero optics and anything sharing the RMS-C footprint, so adding a micro red dot is a simple job.
Same P365 Ecosystem, Softer Recoil
Because this pistol shares its fire control unit and grip module with the standard P365, it works with the huge range of existing P365 holsters and accessories, from flat triggers to X-Series grip modules and Foxtrot lights. Two 10-round steel magazines come in the box, one flush fit for deep concealment and one extended for a fuller grip at the range. If you have been eyeing the P365 but wanted something with less snap and a bit more personality, this is the one to put your hands on.

Frequently Asked Questions
What red dot optics fit the P365-380 Robin's Egg Blue?
The slide has a removable sight plate cut for Sig's RomeoZero series and any micro optic using the Shield RMS-C footprint. The optic cut sits separate from the rear sight dovetail, so you keep your XRAY3 night sights even with a dot mounted. Popular options include the RomeoZero Elite and Shield RMS-C.
Is the P365-380 easier to shoot than the 9mm P365?
Yes, that is really the whole point of this model. The .380 ACP chambering paired with a lightened slide gives you noticeably softer recoil and a slide that is much easier to rack. It is a popular pick for newer pistol owners and anyone with reduced grip strength who still wants a serious carry gun.
Will my existing P365 holsters and accessories work with this pistol?
They will. The P365-380 uses the same grip module and fire control unit as the standard 9mm P365, so it drops into existing P365 holsters and accepts accessories like X-Series grip modules, aftermarket flat triggers, and Foxtrot lights. Keep in mind this version has a manual safety, so make sure your holster accommodates it.
How many magazines come with the Sig P365-380 Robin's Egg Blue?
It ships with two 10-round steel magazines, one flush fit and one extended. The flush mag keeps the grip as short as possible for deep concealment, while the extended mag gives larger hands a full purchase for range days. Standard P365-380 magazines are available separately if you want spares.
