The SIG Sauer P365 Product Line Review

The SIG Sauer P365 Product Line Review

Described as a revolution in the world of subcompact pistols, SIG Sauer first revealed the P365 Nitron Micro Compact at SHOT Show 2018.

Described as “America’s #1 selling pistol”, the P365 has been the best-selling concealed carry pistol in the United States in 2018, 2019, and 2020.

The company has since introduced new variants, creating an all-new line of highly-successful handguns, each with distinctive features.

SIG Sauer P365

Sig Sauer P365

The original SIG P365 was introduced to the market in February of 2018, quickly becoming a runaway success. This handgun is a polymer-framed, striker-fired, modular subcompact pistol chambered in 9x19mm Parabellum, primarily intended for concealed carrying.

What distinguished it from other pistols in the same category was its magazine capacity. Similar products only offered a magazine capacity of 6 or 7 rounds (plus one in the chamber). The P365 comes with a 10-round flush-fit magazine without compromising on dimensions, allowing for a total capacity of 11 rounds (when including a round in the chamber); an unprecedented amount of firepower for a pistol of its category. An extended 12-round magazine is also available, raising the capacity to staggering 13 rounds.

The SIG P365 received several awards since its introduction. Most notably, it won an Industry Choice Award for Handgun of the Year 2018 and an NRA Golden Bullseye Award for Handgun of the Year 2019.

Even though competing manufacturers have since introduced products to try and rival the P365, it remains a highly attractive option for concealed carrying. It offers the capacity of a mid-size pistol in a subcompact package, with all of the reliability and dependability you expect from SIG Sauer.

SIG Sauer P365 Specifications:

  • Cartridge: 9x19mm Parabellum
  • Overall length: 5.8 inches
  • Height: 4.3 inches
  • Width: 1.06 inches
  • Barrel length: 3.1 inches
  • Weight: 17.8 ounces
  • Magazine capacity: 10 rounds (flush-fit magazine), 12 rounds (extended base plate magazine)
    • 15-round XL extended magazines also compatible

SIG Sauer P365 XL

Sig Sauer P365 XL

First introduced in 2019, the SIG P365 XL is also a subcompact pistol. It features slightly enlarged dimensions compared to the original pistol and several changes to improve shootability, particularly for shooters with larger hands.

Despite the XL moniker, the P365 XL isn’t that much larger; half an inch taller, almost one inch longer, and nearly the same width. With that said, these dimensional differences are enough to offer significant changes in shooting comfort and performance.

Most notably, with the flush-fit magazine inserted, this pistol can carry a total of 12+1 rounds. Interestingly, it also sits at the same height as the original P365 with its 12-round magazine, with a virtually identical grip profile. Shooters used to the way the P365 feels in their hands with its 12-round magazine find the P365 XL very familiar.

Other significant changes include an extended beavertail, a longer sight radius, a red dot ready slide, and a SIG X-series flat trigger, with a reduced pull weight compared to the original P365’s curved trigger.

The P365 XL was designed for those who loved the P365 but wished it was a little more comfortable to shoot. If 12 shots is not enough, extended magazines intended for the P365 XL are also available, increasing the capacity to a staggering 15+1 rounds.

SIG Sauer P365 XL Specifications:

  • Cartridge: 9x19mm Parabellum
  • Overall length: 6.6 inches
  • Height: 4.8 inches
  • Width: 1.1 inches
  • Barrel length: 3.7 inches
  • Weight: 20.7 inches
  • Magazine capacity: 12 rounds (XL flush-fit magazine), 15 rounds (XL extended base plate magazine)

SIG Sauer P365 XL ROMEOZERO

Sig Sauer P365XL Remeozero

The SIG P365 XL ROMEOZERO is the P365 XL name when fitted from the factory with SIG’s own ROMEOZERO red dot sight.

The SIG ROMEOZERO sight is an always-on, mini red dot sight designed for pistols and, in particular, the P365 XL. This handgun still features the SIG XRAY illuminated night sights that the P365 and P365 XL models possess.

Because it is otherwise identical to the regular P365 XL, you can use the same magazine and swap out many of the same parts. The only thing you may have to account for is a different holster. The attached ROMEOZERO sight requires a holster with a red dot sight cut; otherwise, it will not fit.

SIG Sauer P365 XL ROMEOZERO Specifications:

  • Cartridge: 9x19mm Parabellum
  • Overall length: 6.6 inches
  • Height: 5.5 inches with the ROMEOZERO sight, 4.8 inches without
  • Width: 1.1 inches
  • Barrel length: 3.7 inches
  • Weight: 20.7 inches
  • Magazine capacity: 12 rounds (XL flush-fit magazine), 15 rounds (XL extended base plate magazine)

SIG Sauer P365 SAS

SIG Sauer P365 SAS

Introduced in October of 2019, the SIG P365 SAS is the latest model in the P365 line of pistols. The P365 SAS is nearly identical to the original P365, including overall dimensions and magazine capacity. However, there is one significant difference: There are no traditional iron sights, leaving a completely smooth, snag-free top end.

Even though it does not have iron sights, that doesn’t mean the P365 SAS is a point-shooting, phone booth distances (4-5 yards max) handgun. The SAS features the innovative FT Bullseye sights. This unique, fiber optic, illuminated sighting system sits flush, embedded directly into the slide.

Although the lack of traditional iron sights means the SAS is precisely 0.2 inches shorter than the regular P365, it otherwise possesses virtually identical dimensions. It should fit without problems in a holster designed for the original P365.

Two sub-variants of the P365 SAS are available. One comes with a ported barrel and slide, reducing muzzle flip, and one without, for those who would prefer not to have the additional muzzle flash.

SIG Sauer P365 SAS Specifications:

  • Cartridge: 9x19mm Parabellum
  • Overall length: 5.8 inches
  • Height: 4.1 inches
  • Width: 1 inch
  • Barrel length: 3.1 inches
  • Weight: 17.8 ounces
  • Magazine capacity: 10 rounds (flush-fit magazine), 12 rounds (extended base plate magazine)
    • 15-round XL extended magazines also compatible
