The '''SIG Sauer P365''' is a striker-fired subcompact semi-automatic pistol manufactured by SIG Sauer, intended for everyday carry<ref name="SoldierSystems-P365">{{cite web|title=Introducing the SIG Sauer P365|url=http://soldiersystems.net/tag/sig-sauer/|website=Soldier Systems Daily|accessdate=8 January 2018}}</ref> and is produced in Newington, New Hampshire.<ref name="SIGSauer-P365">{{cite web |title=P365 |url=https://www.sigsauer.com/products/firearms/pistols/p365/ |website=sigsauer.com |accessdate=March 8, 2020}}</ref>

==Features== The P365 is a striker fired, short-recoil handgun with a stainless steel slide, treated with a black Nitron finish, and a stainless steel frame along with a polymer grip module.

The slide has serrations on both front and back for easy slide manipulation.

=== Magazine === It is primarily chambered in 9×19mm Parabellum and is rated for +P (higher pressure) ammunition while utilizing offset double-stack magazines.<ref name="SIGSauer-P365" />

The polymer grip accepts a double-stack 10-round, 12-round, 15-round magazine, or 17-round magazine.

A variant chambered in .380 ACP was introduced in February 2022.

The magazine is released by a triangular button on the grip located at the undercut trigger guard section.

Per SIG Sauer, the P365 has the lowest bore-axis ratio of any handgun currently made.<ref name="shot2018">Live broadcast from the 2018 SHOT Show</ref>

=== 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.{{efn|"the front sight completely covers the bullseye of the target."<ref>{{cite web |url=https://www.sigsauer.com/support/faqs/ |title=SIG Sauer FAQs |publisher=sigsauer.com |accessdate=September 2, 2019 |archive-date=September 21, 2019 |archive-url=https://web.archive.org/web/20190921003817/https://www.sigsauer.com/support/faqs/ |url-status=dead }}</ref>}}

=== Attachments === A proprietary rail is located below the barrel of the P365, P365x and P365xl models.<ref name="SoldierSystems-P365" />

Both red and green lasers and a light will be offered as accessory items for this proprietary rail.<ref name="PDW-LimaFoxtrot">{{cite web|title=SIG Rolls Out Lima365 Laser, Foxtrot365 Flashlight for P365|url=https://www.personaldefenseworld.com/2018/01/sig-sauer-lima365-laser/|website=Personal Defense World|date=24 January 2018 |accessdate=30 January 2018}}</ref>

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.<ref name="OmahaOutdoors-P365">{{cite web|title=Breaking: The New SIG Sauer P365|url=https://www.omahaoutdoors.com/blog/breaking-new-sig-sauer-p365/|website=Omaha Outdoors|date=8 January 2018|accessdate=8 January 2018}}</ref>

== Comparisons == The grip encloses a stainless steel fire control unit (FCU) similar to that in the SIG Sauer P320.<ref name="SoldierSystems-P365"/><ref name="AMR-P365">{{cite web|title=SIG Sauer Announces P365 Pistol|url=https://www.americanrifleman.org/articles/2018/1/8/sig-sauer-announces-p365-pistol/|website=The American Rifleman|publisher=National Rifle Association|accessdate=8 January 2018}}</ref>

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.<ref>{{cite journal|title=Evolution of the SIG P210|journal=Firearms News|date=February 2018|issue=3}}</ref>

Compared to the SIG Sauer P290, the P365 is slightly larger and has a lighter striker trigger pull of {{convert|5.5|to|6.5|lb-f|N|0|lk=on|abbr=on}} versus the P290 at {{convert|9|lb-f|N|0|lk=on|abbr=on}}.<ref name="SoldierSystems-P365"/> 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 {{convert|.46|inch|mm}} ''taller'' than a Glock 19 with its standard 15-round magazine.<ref>{{cite journal|title=SIG Sauer releases 15-round mags for P365 models|url=https://www.militarytimes.com/2019/05/29/sig-sauer-releases-15-round-mags-for-p365-models/|journal=MilitaryTimes|date=May 29, 2019}}</ref><ref>{{cite journal|title=Sig Sauer Announces 15 Round Mag for P365 Series Pistols|url=https://www.guns.com/news/2019/05/29/sig-sauer-announces-15-round-mag-for-p365-series-pistols|website=Guns.com|date=May 29, 2019}}</ref><ref>{{Cite web|url=https://www.sigsauer.com/store|title=SIG Store - Shop Online at the SIG Sauer Web Store|website=www.sigsauer.com}}</ref><ref>{{Cite web|url=https://us.glock.com/en/pistols/g19|title = Glock 19: The all-round talent}}</ref>

==Variants== thumb|right|A P365 XL with manual safety and 12-round flush-fit magazine

===P365 XL=== In June 2019, the P365 XL was released.<ref name=Moss/>

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.<ref name="Moss" />

The rear sight on the P365 XL slide is removable, to allow a red dot sight to be attached.<ref name="Moss">{{cite web |url=https://www.thefirearmblog.com/blog/2019/07/09/sig-sauer-p365-xl-now-shipping/ |title=New SIG Sauer P365 XL Now Shipping |first=Matthew |last=Moss |website=thefirearmblog.com |date=July 9, 2019 |accessdate=September 5, 2019}}</ref>

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.<ref>{{cite web |url=https://www.guns.com/news/2019/10/03/sig-sauer-announces-new-innovative-p365-sas-now-shipping |title=SIG Sauer Announces New, Innovative P365 SAS Now Shipping |first=Chris |last=Eger |website=guns.com |date=October 3, 2019 |accessdate=January 17, 2020}}</ref>

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.<ref>{{cite web |url=https://www.guns.com/news/2019/11/27/sig-365-sas-initial-thoughts |title=The Sig P365 SAS – First 100 Rounds and Initial Thoughts |first=Seth |last=Rodgers |website=guns.com |date=November 27, 2019 |accessdate=January 17, 2020}}</ref>

Other than a slight reduction in height, the SAS variant has the same dimensions and weight as the original P365.<ref name="SASspecs" />

=== 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.<ref>{{Cite web|title=P365X Romeozero|url=https://www.sigsauer.com/p365x-romeozero.html|access-date=2021-04-17|website=sigsauer.com|language=en}}</ref>

===P365-380=== In February 2022, SIG announced a variant chambered in .380 ACP, available both with and without a manual safety.<ref>{{cite news |url=https://www.guns.com/news/2022/02/18/sig-debuts-380-acp-variant-of-the-p365 |title=SIG Debuts .380 ACP Variant of the P365 |first=Chris |last=Eger |website=guns.com |date=February 18, 2022 |accessdate=February 18, 2022}}</ref>

=== P365-XMACRO & XMACRO COMP === During 2022, SIG introduced a larger variant, branded as XMACRO, with a 17-round capacity and measuring {{convert|5.2|in|cm}} high and {{convert|6.6|in|cm}} long and a {{convert|3.1|in|cm|adj=on}} barrel.<ref>{{cite news |url=https://www.americanrifleman.org/content/new-for-2022-sig-sauer-p365-xmacro |title=New For 2022: SIG Sauer P365-XMacro |website=American Rifleman |date=November 12, 2022 |accessdate=November 12, 2022}}</ref> SIG renamed the XMACRO to the XMACRO COMP with the release of the new XMACRO, featuring the 17-round grip module with the slide and barrel from the P365 XL. <ref name=":0" />

=== ROSE P365 === In January 2023, the '''P365-XL COMP ROSE''' and '''P365-380 ROSE''' was released. In collaboration with Lena Miculek, ROSE by SIG Sauer is a program designed to encourage and foster a community of female shooters.

===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).<ref name=AXG/>

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).<ref name="AXG">{{cite news |url=https://osagecountyguns.com/blog/sig-sauer-p365-axg-legion-announced.html |title=Sig Sauer P365 AXG Legion Announced |website=osagecountyguns.com |date=October 2023 |accessdate=October 30, 2023}}</ref>

===P365XL Spectre=== SIG has introduced "Spectre" branded variants of the P365 XL through SIG Custom Works.

The first P365XL Spectre{{efn|SIG styles the Custom Works offerings as P365XL Spectre, without a space before the "XL".}} was introduced in June 2021 featuring a distressed finish and an X-shaped cutout on top of the slide.<ref>{{cite web |url=https://www.guns.com/news/2021/06/21/sig-sauer-shows-off-new-spectre-p320-p365xl |title=SIG Sauer Shows Off New Spectre P320, P365XL |first=Chris |last=Eger |website=Guns.com |date=June 21, 2021 |accessdate=March 12, 2022}}</ref>

=== 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.<ref>{{Cite web |title=Sig P365 Fuse Review |url=https://www.craftholsters.com/sig/guides/sig-p365-fuse-review |access-date=December 6, 2024 |website=craftholsters.com}}</ref> The FUSE also comes with two 21-round and one 17-round steel magazines.<ref>{{Cite web |title=P365-Fuse |url=https://www.sigsauer.com/p365-fuse.html |access-date=December 6, 2024 |website=sigsauer.com}}</ref>

The P365-FUSE is currently the newest P365 variant to be released.

=== Compliance-based variants === For Massachusetts Attorney General compliance requirements, a model with a manual safety and loaded chamber indicator is available.
