Sig Sauer P365 Series Compared: Models, Specs, and Differences

The P365 name covers several SIG SAUER pistol configurations, not one set of specifications. This guide compares the original P365, X/XL, SAS, XMacro, AXG, FUSE, ROSE and specialty variants using manufacturer references. A shared family name does not establish ammunition, holster, magazine or optic compatibility.

Editorial specification review: October 23, 2026. Each model section identifies the exact reference SKU. This is a factual comparison, not a new hands-on test or a ranking of defensive effectiveness. Listing a model does not establish current stock, legal eligibility or suitability for an individual.

P365 Models Compared at a Glance

Read the model names as configuration labels. The table below groups the main differences; the model sections provide exact specifications and direct manufacturer sources. This selection is not an exhaustive catalog of every finish, dealer edition or restricted-capacity package.

Model group	Main distinction
P365 / P365-380 / SAS	Short format; caliber and sight system differ. SAS is not optic-ready in the reference.
P365X / XL / XL Spectre	XSeries grip; 3.1-inch X versus 3.7-inch XL/non-Comp Spectre references.
XMacro / Tacops / Comp	Standard and Tacops: 3.7-inch barrels. Comp: 3.1-inch barrel and slide expansion chamber.
AXG Legion / Equinox / LUXE / DH3 AXG	Metal grip-module variants with different dimensions, calibers and magazine packages.
FUSE / FUSE COMP / XF DH3	Distinct long-slide configurations; do not share one barrel or weight figure across them.
ROSE / XL COMP .380	ROSE is a package family; XL COMP .380 is a separate model from 9mm XL Comp ROSE.
MACH3D	Announced configuration; SIG still labels it coming soon on the review date.

Before you carry: plan for the legal side. A self-defense incident can bring legal costs even when you acted lawfully. Carry insurance and legal-defense memberships differ a lot in what they cover, when they pay, and whether they cover criminal and civil defense. Compare them in our concealed carry insurance guide before you choose.

How to Read These Specifications

Magazine capacity below means rounds held in the magazine. It excludes the chamber. “12+1” elsewhere means a 12-round magazine plus one chambered round; it is capacity notation, not loading guidance. Different included magazines and restricted-capacity SKUs must be identified separately.

Dimensions are overall length × height × width in inches unless stated otherwise. They are SIG-listed values, not measurements of our own samples. Installed optics, controls and magazine configuration can affect dimensions. A barrel length is not a slide or overall length.

Weight is the manufacturer’s listed ounces field. Where SIG explicitly says “with magazine,” that wording is retained. Other rows do not consistently define the measurement basis, so they should not be treated as standardized loaded weights. Conflicting values are flagged in the relevant model section.

About the P365 Series

The family includes different calibers, grip modules, slide designs and factory packages. The serialized fire control unit is part of its modular design, but that does not make every component or caliber interchangeable. Use the applicable manual and manufacturer compatibility information; this guide does not provide conversion or modification instructions.

P365 Series: Model Breakdown

Each table describes one identified configuration. Manual-safety status and included magazine capacities refer only to that SKU. Product photos are illustrations and may show a different production version or factory package.

P365 (The Original)

Reference SKU	365-9-BXR3P
Caliber	9mm Luger
Magazine capacity	10 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	17.8 oz
Dimensions (L × H × W)	5.8 × 4.3 × 1.1 in
Manual safety	No

The optic-ready reference has a polymer grip module, curved trigger and XRAY3 sights. Earlier non-optic-ready P365 slides also exist; the family name alone does not identify the slide version.

P365-380

Reference SKU	365-380-BSS
Caliber	.380 ACP
Magazine capacity	10 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	15.7 oz
Dimensions (L × H × W)	5.8 × 4.2 × 1.0 in
Manual safety	No

This is the .380 ACP configuration, not a 9mm conversion of the reference above. SIG lists SIGLITE sights and a polymer grip module. Do not infer ammunition or component interchangeability from external similarity.

P365 SAS

Reference SKU	365-9-SAS
Caliber	9mm Luger
Magazine capacity	10 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	17.8 oz
Dimensions (L × H × W)	5.8 × 4.1 × 1.0 in
Manual safety	Not listed in reference row

The flush-mounted FT Bullseye sight and flat controls distinguish the SAS. SIG lists this reference as not optic-ready. Its sight system is different from conventional front and rear sights; no sight-acquisition or defensive-performance advantage is established here.

P365 X

Reference SKU	365X-9-BXR3P-MS
Caliber	9mm Luger
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	17.8 oz
Dimensions (L × H × W)	5.8 × 4.8 × 1.1 in
Manual safety	Yes

The P365X combines a 3.1-inch barrel with the taller XSeries grip and a flat trigger. This reference has a manual safety; other P365X SKUs differ. It shares the selected XL’s listed height, not its barrel or overall length.

P365 XL

Reference SKU	365XL-9-BXR3
Caliber	9mm Luger
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	20.7 oz
Dimensions (L × H × W)	6.6 × 4.8 × 1.1 in
Manual safety	Not specified in reference row

The XL has a 3.7-inch barrel and XSeries grip. Its selected height matches the P365X, while its overall length is greater. Production-era optic cuts and package contents can differ.

P365 XL Spectre

Reference SKU	P365V001
Caliber	9mm Luger
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	20.7 oz
Dimensions (L × H × W)	6.6 × 4.8 × 1.1 in
Manual safety	Not specified in reference row

The non-Comp Spectre reference has a distressed slide finish and laser-engraved grip texture. The XL Spectre Comp is a separate configuration: do not apply this 3.7-inch barrel specification to it.

P365 XMacro

Reference SKU	365XCA-9-BXR3
Caliber	9mm Luger
Magazine capacity	17 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	22 oz (with magazine)
Dimensions (L × H × W)	6.6 × 5.2 × 1.1 in
Manual safety	No

The standard XMacro reference has a 3.7-inch barrel, polymer Macro grip and M1913 rail. It does not have the integrated slide compensator of the XMacro Comp.

P365 XMacro Tacops

Reference SKU	365XCA-9-TACOPS
Caliber	9mm Luger
Magazine capacity	17 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	22.8 oz
Dimensions (L × H × W)	6.6 × 5.2 × 1.4 in
Manual safety	No

The reference package includes four 17-round magazines, an enhanced slide catch and detachable magwell. Its 3.7-inch barrel is not the XMacro Comp configuration. The listed 1.4-inch width should not be replaced by the standard XMacro’s 1.1-inch figure.

P365 XMacro Comp

Reference SKU	365XCA-9-COMP-MS
Caliber	9mm Luger
Magazine capacity	17 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	21.5 oz
Dimensions (L × H × W)	6.6 × 5.2 × 1.1 in
Manual safety	Yes

An integrated slide expansion chamber distinguishes this model from the standard XMacro and Tacops. The reference uses a 3.1-inch barrel despite having the same listed overall length as those selected models. Manufacturer recoil-reduction marketing is not an independently measured result in this article.

P365 AXG Legion

Reference SKU	365AXGCA-9-LEGION-10
Caliber	9mm Luger
Magazine capacity	10 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	26 oz
Dimensions (L × H × W)	6.6 × 5.2 × 1.4 in
Manual safety	No

The alloy AXG grip, G10 panels, magwell and integrated slide expansion chamber distinguish the Legion. This explicitly identified reference is the three-10-round-magazine SKU; 17-round and optic-equipped packages also exist and are separate configurations.

P365 FUSE

Reference SKU	365XF-9-BFO
Caliber	9mm Luger
Magazine capacity	17 / 21 rounds; chamber excluded
Barrel length	4.3 in
SIG-listed weight	23.1 oz
Dimensions (L × H × W)	7.2 × 5.1 × 1.1 in
Manual safety	No

The standard FUSE reference has a 4.3-inch barrel, laser-textured polymer grip and fiber-optic front sight. It includes one 17-round and two 21-round magazines. The FUSE COMP below is a different model, not the same barrel specification.

P365 XL Comp ROSE

Reference SKU	365XL-9-ROSE-MS
Caliber	9mm Luger
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	20.7 oz
Dimensions (L × H × W)	6.6 × 4.8 × 1.1 in
Manual safety	Yes

The 9mm ROSE reference has an XL-style polymer grip and integrated slide expansion chamber. ROSE also includes educational material and a storage package; verify contents for the specific edition. A bundled case does not establish compliance with every storage law.

P365-380 ROSE

Reference SKU	365-380-ROSE-MS
Caliber	.380 ACP
Magazine capacity	10 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	Withheld: source discrepancy
Dimensions (L × H × W)	5.8 × 4.2 × 1.1 in
Manual safety	Yes

SIG’s table lists 36.9 oz for this manual-safety SKU, but 15.7 oz with magazine for 365-380-ROSE without the manual safety. The listing does not explain the large difference. We withhold the reference weight pending manufacturer clarification rather than treating either figure as universal.

P365-LUXE .380

Reference SKU	365AXG-380-COMP-LUXE
Caliber	.380 ACP
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	22.1 oz
Dimensions (L × H × W)	6.75 × 4.65 × 1.24 in
Manual safety	No

The LUXE combines an XL AXG grip module with a pearlescent black finish. Its reference includes three 12-round magazines. It differs from the polymer P365-380 and from ROSE; optic-equipped LUXE packages have separate specifications.

P365-XL COMP .380

Reference SKU	365XL-380-COMP
Caliber	.380 ACP
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	18.4 oz (with magazine)
Dimensions (L × H × W)	Length 6.6 in; width 1.24 in; height withheld
Manual safety	No

This .380 ACP model uses an XSeries polymer grip and an integrated slide expansion chamber. SIG’s table lists height as 6.6 inches, the same as overall length. We have not independently confirmed that value and omit it rather than substitute an assumed height.

P365-FUSE COMP

Reference SKU	365XF-9-COMP
Caliber	9mm Luger
Magazine capacity	17 / 21 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	25.4 oz (SIG-listed)
Dimensions (L × H × W)	7.2 × 5.7 × 1.4 in
Manual safety	No

This reference uses a 3.7-inch barrel and integrated slide expansion chamber. SIG publishes 25.4 oz alongside 703.1 g, which are not equivalent. We reproduce the ounces field with that discrepancy disclosed; weight and dimensions have not been independently measured.

P365-DH3 AXG

Reference SKU	365AXGF-9-DH3
Caliber	9mm Luger
Magazine capacity	17 / 21 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	25.3 oz (with magazine)
Dimensions (L × H × W)	7.2 × 5.2 × 1.4 in
Manual safety	No

The Daniel Horner signature AXG model has a metal grip module and Coyote finish. Its reference includes one 17-round and two 21-round magazines. Do not substitute standard FUSE or Legion weights for this configuration.

P365-XF DH3

Reference SKU	365XF-9-DH3
Caliber	9mm Luger
Magazine capacity	17 / 21 rounds; chamber excluded
Barrel length	3.7 in
SIG-listed weight	22.9 oz (with magazine)
Dimensions (L × H × W)	7.2 × 5.2 × 1.4 in
Manual safety	No

The XF DH3 uses a polymer grip rather than the AXG module. It shares the selected DH3 AXG’s listed dimensions and barrel length but has a different listed weight. These manufacturer specifications do not establish a performance ranking.

P365-AXG EQUINOX

Reference SKU	365AXG-9-COMP-EQ
Caliber	9mm Luger
Magazine capacity	12 rounds; chamber excluded
Barrel length	3.1 in
SIG-listed weight	22.1 oz (with magazine)
Dimensions (L × H × W)	6.8 × 4.7 × 1.2 in
Manual safety	No

This Custom Works reference has an AXG grip module, G10 panels and Equinox finish. SIG lists three 12-round magazines. AXG denotes a grip family, not identical dimensions or capacity across Equinox, Legion, LUXE and DH3 models.

P365 Snakebite and P365-XL Snakebite

The Snakebite pistols are retailer editions of the standard P365 and P365-XL, sold through Bass Pro Shops and Cabela’s. They change the finish and sights, not the core pistol. Specifications below are from the Bass Pro Shops listings, checked October 28, 2026; SIG does not list them as separate catalog models.

Retailer model number	365-9-TXR3P-C
Caliber	9mm
Barrel length	3.1 in
Finish (as listed)	Bronze/coyote PVD slide accents; black grip module
Sights	SIG X-Ray3 day/night
Optic-ready	Yes
Magazines included	One 10-round and one 17-round extended (per listing)
Listed price	$549.99

Retailer model number	365XL9RTXRPCVPX
Caliber	9mm
Barrel length	3.7 in
Finish (as listed)	Black slide; coyote grip
Sights	SIG X-Ray3 day/night
Optic cut	RMSc footprint
Trigger	SIG X flat trigger
Magazines included	Two
Listed price	$649.99
Retailer note	Listed as a Bass Pro Shops and Cabela’s exclusive

Because the frames and slides match the standard P365 and P365-XL, holsters made for those models should fit, but confirm sight, optic and light configuration with the holster maker before buying. Our SIG P365 holster guide covers P365 and P365 XL options. Concealed Carry Society does not earn a commission from Bass Pro Shops or Cabela’s.

P365-MACH3D — Coming Soon

Reference SKU	365XCA-9-BXR3P-M3D
Caliber	9mm Luger
Magazine capacity	17 rounds; chamber excluded
Barrel length	3.4 in
SIG-listed weight	23 oz (with magazine)
Dimensions (L × H × W)	7.2 × 5.25 × 1.4 in
Manual safety	No

On October 23, 2026, SIG’s page still labels MACH3D “COMING SOON.” The specifications describe an announced configuration, not verified retail availability. We have not handled or tested this model, and the listing does not establish a delivery date.

What This Comparison Does—and Does Not—Establish

The tables establish published configuration differences, not which model is “best.” Handling comfort, perceived recoil, reliability and accuracy require clearly identified samples and documented testing. A compensator’s presence alone does not establish a measured benefit for a particular user or ammunition.

This revision involved source checking and editing; it did not include new firing, endurance or handling tests. The version reviewed did not contain model-specific first-person test passages or supporting test logs. The original owner’s broader experience should not be read as proof that every variant listed here was personally tested. No new firsthand experience has been invented.

Accessories for the P365 Series

The P365 family has a range of factory and aftermarket accessories. The categories below are an overview; compatibility varies by model and configuration.

1. Holsters: Fit listings depend on the exact pistol model and any installed accessories.
2. Magazines: Capacity, included magazines, and compatibility vary by model and state-compliant configuration.
3. Optics: Check the exact slide’s optic footprint and the optic manufacturer’s compatibility listing.
4. Grip Modules: Grip-module options differ across the P365 family; confirm compatibility with the specific configuration.
5. Lighting and Lasers: Rail type and accessory fit vary by model.
6. Triggers: Factory trigger styles differ across models and production versions.
7. Magazine Extensions and Adapters: Compatibility and capacity depend on the exact magazine and pistol configuration.
8. Custom Works and Cerakote Finishes: Some factory variants differ in finish, grip panels, and package contents.

Accessory compatibility depends on the exact model, production version, and installed equipment. Check the accessory manufacturer’s fit listing.

For holster options for the P365, P365X, P365 XL, and P365 SAS, see our P365 holster guide. Confirm the manufacturer’s fit listing for your exact model and any installed accessories; do not assume these options fit an XMacro, AXG Legion, FUSE, or ROSE configuration.

P365 Accessory Links

These existing accessory links are not exact-model fit certifications. Check the manufacturer’s current compatibility information. Any discount is subject to current merchant terms and exclusions; this review did not verify coupon eligibility.

Responsible Ownership and Storage

Read the current SIG SAUER manual and safety warnings applicable to the exact model before handling it. A manual safety is not a substitute for safe handling. Keep fingers away from the trigger when not firing and keep the muzzle directed safely. Seek qualified instruction rather than treating a comparison article as operating training.

SIG’s P365 operator’s manual directs secure storage of an unloaded, cleared firearm in a locked location inaccessible to children and unauthorized people. Store ammunition separately and follow current local storage and transport requirements. Consult official legal sources for possession, magazine and carry rules; a manufacturer’s state-compliant label is not an individual legal determination.

P365 Comparison Questions

Are the P365X and P365 XL the same size?

No. The selected references are both 4.8 inches high, but the P365X is 5.8 inches long with a 3.1-inch barrel; the XL is 6.6 inches long with a 3.7-inch barrel. The exact SKUs are identified above.

Does every XMacro have a compensator?

No. The standard XMacro and Tacops references have 3.7-inch barrels without the integrated slide expansion chamber. The XMacro Comp reference has a 3.1-inch barrel and the chamber. The shared XMacro name does not make their slides and barrels identical.

Does ROSE mean one specific pistol?

No. This article separates the 9mm XL Comp ROSE from the smaller .380 ACP ROSE. Their caliber, dimensions and magazine configurations differ. The ROSE name also covers educational and storage-package elements; it is not one universal specification.

Are P365 holsters and optics interchangeable across the family?

Do not assume so. Exact slide version, grip module, rail, optic footprint and attached equipment matter. Confirm explicit manufacturer fit information for the specific configuration. A shared P365 label is insufficient evidence of compatibility.

Is MACH3D available now?

SIG’s product page still says “COMING SOON” as of October 23, 2026. We have not verified retail stock or a delivery date. The announced model’s specification table is not proof of availability.

Sources and Review Notes

Direct manufacturer links accompany every model table. Figures were checked October 23, 2026 and remain subject to manufacturer changes. Known source issues are disclosed for .380 ROSE weight, XL COMP .380 height and FUSE COMP ounce/gram equivalence. We do not silently correct manufacturer data or infer undocumented measurements.

The five-model dimensions graphic predates this review and represents only its identified configurations. It does not depict the full lineup. Retail listings, affiliate descriptions and photos may refer to different SKUs; manufacturer specifications and the exact product identity take priority.
