Sights

The P365 is offered with Tritium XRAY3 Day/Night Sights and two 10-round magazines; one flush fit and the other with an extended finger tab, and a stainless steel frame with polymer grip module. The sights are green tritium three-dot night sights that are made of steel and are capable of being used to cycle the slide in the case of one handed use being necessary. Aiming is by combat sighting.

Attachments

A proprietary rail is located below the barrel. Both red and green lasers and a light will be offered as accessory items for this proprietary rail. Adapters to convert the proprietary rail to a standard rail for use with standard rail accessories are also available.

Disassembly

Disassembly requires no tools and does not require that the trigger be pulled.

Comparisons

The grip encloses a stainless steel fire control unit (FCU) similar to that in the SIG Sauer P320. The striker firing system is nearly identical to that in the P320. The short recoil locking system is the SIG Sauer system created by SIG Sauer in 1975 for a Swiss Army contract by the then-existing Swiss Industrial Group (''Schweizerische Industrie Gesellschaft'', SIG). The SIG Sauer system improved upon the Petter–Browning system used in the French Modèle 1935A, which SIG had licensed from SACM in 1937 and used in the SIG P210 handgun design, but is not the same system, having been considerably improved upon. Compared to the SIG Sauer P290, the P365 is slightly larger and has a lighter striker trigger pull of versus the P290 at . The P290RS has a restrike capability, but also has a long double-action only trigger pull. The takedown system is similar to that of the P320, in that a lever is turned down with the slide locked back to release the slide from the frame. A P365 with its optional 15-round magazine is ''taller'' than a

with its standard 15-round magazine.

Variants

P365 XL

In June 2019, the P365 XL was released. The P365 XL utilizes the same fire control unit (FCU) as the P365, while having a larger grip module that accepts 12-round flush magazines, a flat trigger, and a longer slide and barrel. The rear sight on the P365 XL slide is removable, to allow a red dot sight to be attached. The slides and frames of the variants are interchangeable; for example, the longer slide (and barrel) of a P365 XL can be used on a P365 frame and vice versa.

P365 SAS

In October 2019, a SIG Anti-Snag (SAS) version of the P365 was released. The SAS variant has an optional ported barrel and slide, no front sight, flush takedown and slide catch levers on the frame, and an embedded and flush fiber optic sight at the rear. Other than a slight reduction in height, the SAS variant has the same dimensions and weight as the original P365.

P365X

In 2021, SIG released the P365X, which incorporated many of the features of the P365 XL, including a flat trigger, a removable rear sight which can be substituted for an optic mount, and a longer hand grip which accommodates flush fit 12-round magazines, but without the longer slide. At launch it was only being sold with the RomeoZero red dot sight preinstalled.

P365-380

In February 2022, SIG announced a variant chambered in .380 ACP, available both with and without a manual safety.

P365-XMACRO

During 2022, SIG introduced a larger variant of the P365, branded as XMACRO, with a 17-round capacity and measuring high and long and a barrel.

P365 AXG

In October 2023, SIG announced a "Legion" variant of the P365, featuring a grey finish, grip module with grip panels, and pre-installed magazine well (magwell). It also features a removable plate on the slide (allowing installation of a red dot sight) and ships with three 17-round magazines (where legal).

Specifications

P365XL Spectre

SIG has introduced "Spectre" branded variants of the P365 XL through SIG Custom Works. The first P365XL Spectre was introduced in June 2021 featuring a distressed finish and an X-shaped cutout on top of the slide. A revised version was introduced in October 2021 that added a gold-colored barrel and skeletonized the flat trigger. In February 2022, the P365XL Spectre Comp was introduced with an integrated compensator; it also has a gold-colored barrel, but its flat trigger is not skeletonized.

P365-FUSE

In June 2024, the P365-FUSE was released. Designed to bridge the gap between compact and full-size carry pistols, the P365-FUSE has an overall length of 7.2" and a 4.3" barrel. The FUSE also comes with two 21-round and one 17-round steel magazines. The P365-FUSE is currently the newest P365 variant to be released.
