Technical Specifications

Key Features – The .40 S&W, Perfected for Gen5

The .40 S&W Caliber – The Balanced Choice

The .40 S&W occupies a unique position in the handgun caliber spectrum.

First, this caliber bridges the gap between 9mm Luger and .45 ACP, offering more stopping power than 9mm while providing higher capacity than .45 ACP . Therefore, it represents a balanced compromise for shooters who want both power and capacity.

Second, the caliber gained widespread adoption by the FBI and major law enforcement agencies throughout the 1990s and 2000s. Consequently, .40 S&W ammunition remains widely available and battle-proven.

Third, the G23 Gen5 delivers this power in a compact, controllable package. The GLOCK polymer frame absorbs much of the .40 S&W’s recoil impulse, making follow-up shots faster than many expect.

Fact: The .40 S&W was developed in 1990 as a joint project between Smith & Wesson and Winchester. GLOCK was among the first manufacturers to offer pistols in this caliber, and the G23 quickly became a law enforcement standard.

Compact Frame – G19 Size, .40 S&W Power

The GLOCK 23 shares the same dimensions as the legendary GLOCK 19.

To begin with, the overall length measures 185mm (7.28 inches) – identical to the G19 . Therefore, the pistol fits comfortably in holsters and hands alike.

In addition, the height measures 129mm (5.08 inches) – also matching the G19. Consequently, the pistol conceals well under a jacket or in an inside-the-waistband holster.

Despite the compact dimensions, the magazine holds 13 rounds of .40 S&W – substantial firepower in a concealable package .

For shooters who own a G19 in 9mm, the G23 offers the same ergonomics and feel with the added power of the .40 S&W cartridge.

MOS (Modular Optic System) – Optics Ready for Duty

The MOS configuration comes standard on the G23 Gen5.

First, the slide features precision machining for popular optic sights. Therefore, you can mount miniature red dot sights without aftermarket milling .

Second, the system includes adapter plates for various footprints. The pistol accepts Trijicon RMR, Holosun 407C/507C, Leupold DeltaPoint Pro, and other popular optics.

Third, the MOS system is factory-engineered. Consequently, the optic sits at the correct height and maintains zero under the .40 S&W’s recoil.

For professionals, the MOS system allows for a red dot sight – proven to improve target acquisition speed and accuracy in defensive scenarios .

Front Serrations (FS) – Enhanced Slide Manipulation

The Front Serrations provide a distinct practical advantage.

To start, they offer an additional gripping surface at the front of the slide. Therefore, press checks, malfunction clearances, and slide manipulations become easier and more secure .

Additionally, the serrations prove particularly useful when you have a mounted optic. Consequently, you have a grippy surface that the red dot sight does not block.

Furthermore, the front serrations complement the existing rear cocking serrations. Together, they provide a complete slide manipulation package.

nDLC Finish – Extreme Durability for Duty

The nDLC (non-Diamond Like Carbon) finish represents GLOCK’s most advanced surface treatment .

To begin with, it provides tougher and more durable protection than previously used finishes. Therefore, rust and scratch resistance improves significantly .

Additionally, the finish offers self-lubricating properties to some degree. Consequently, the pistol functions reliably even when you lubricate it less frequently.

Above all, the nDLC finish helps the pistol work in adverse conditions – from sweat and rain to dust and dirt .

GLOCK Marksman Barrel (GMB) – Enhanced Accuracy

The GLOCK Marksman Barrel comes standard on all Gen5 pistols .

First, the barrel features enhanced rifling based on the proven polygonal barrel design. Therefore, it delivers improved accuracy compared to previous generations.

Second, the cold hammer-forging process ensures consistency and durability. This process produces barrels that last for tens of thousands of rounds.

Third, independent testing has confirmed the GMB’s accuracy potential. In various evaluations, the Gen5 barrels have produced groups under 40mm at 25 meters – exceptional for a factory duty pistol .

Flared Magwell – Faster Reloads Under Stress

The flared magwell represents a significant Gen5 improvement.

First, the larger opening funnels the magazine into the grip, especially during high-stress situations where fractions of seconds matter . Therefore, reloads become faster and more positive.

In addition, the enlarged front of the floor plate makes pulling the magazine free easier during a malfunction or reload .

Third, the orange follower provides high visibility, allowing you to clearly see when the magazine is empty .

No Finger Grooves – Universal Fit

The Gen5 frame removes the finger grooves that characterized earlier generations.

To begin with, the grip now fits a wider range of hand sizes comfortably. Therefore, shooters with small, medium, or large hands can all achieve a comfortable grip .

Second, the RTF (Rough Textured Frame) texture provides excellent grip traction without feeling too aggressive against skin or clothing.

Third, the reversible magazine catch is enlarged and can be switched for left-handed shooters .

Fourth, the ambidextrous slide stop lever makes manipulation easy for both right and left-handed operators .

Modular Beavertail Backstrap System (MBS)

The Gen5 frame includes GLOCK’s Modular Beavertail Backstrap System .

First, the system includes multiple backstraps in different sizes. Therefore, you can customize the grip circumference to fit your hand size perfectly.

Second, the beavertail design prevents slide bite and promotes a high, consistent grip.

Third, you can quickly and easily interchange the backstraps without special tools.

Safe Action Trigger System – Consistent from First Shot to Last

The GLOCK Safe Action System serves as the heart of every GLOCK pistol.

First, the system incorporates three automatic safeties – a trigger safety, a firing pin safety, and a drop safety. These safeties disengage sequentially as you pull the trigger and automatically reengage when you release it .

Second, the trigger pull feels the same from the first shot to the last. Therefore, no confusing transition exists from a heavy double-action pull to a light single-action pull.

Third, the system requires no manual safety lever – you simply draw, aim, and pull the trigger. The three automatic safeties prevent accidental discharge when you use a proper holster .

Dual Recoil Spring – Durable Performance

The Gen5 .40 S&W models feature a dual recoil spring assembly.

First, the dual spring system absorbs the .40 S&W’s recoil impulse effectively. Therefore, the pistol remains comfortable to shoot even during extended range sessions.

Second, the system is extremely durable, designed to last for thousands of rounds without replacement.

Third, the dual springs contribute to the pistol’s reputation for reliability across various ammunition types and conditions .

What’s Included

GLOCK 23 Gen5 MOS FS vs. Other GLOCK Models

Verdict: The GLOCK 23 Gen5 MOS FS is the ideal choice for shooters who want the power of .40 S&W in a compact, concealable package. It shares the same dimensions as the beloved G19 but chambers the more powerful .40 S&W cartridge. For those who prefer 9mm, the G19 remains an excellent choice. For duty use with a full-size frame, the G22 Gen5 MOS offers higher capacity. For deep concealment, the G27 Gen5 serves as the subcompact option .

For shooters who own a G19 in 9mm, the G23 offers the same ergonomics and holster compatibility with the added power of .40 S&W.

Who Is This Pistol For?

For Concealed Carry (with license)

The GLOCK 23 is specifically designed for discreet, comfortable all-day concealed carry. The compact dimensions (same as G19) make it easy to conceal under a jacket or in an inside-the-waistband holster. Additionally, the .40 S&W provides more stopping power than 9mm in a still-manageable package .

For professionals who work undercover, the G23 remains the top choice .

For Duty / Law Enforcement

Store it alongside your rem 700 rifle for hunting or benelli m4 shotgun for home defense – the G23 covers your handgun needs with .40 S&W authority.

For Shooters Upgrading from Older G23s

Carry the G23 Gen5 MOS FS as a backup to your rem 700 bolt action rifle. The .40 S&W cartridge is powerful enough for finishing shots on wounded game. Moreover, the 13-round capacity provides peace of mind in the field.

The .40 S&W Caliber – A Brief History

The .40 S&W cartridge has an interesting origin story.

Fact: In 1986, the FBI experienced the infamous Miami shootout, where a 9mm round failed to incapacitate a subject. This incident led the FBI to seek a cartridge with more stopping power. The result was the development of the 10mm Auto. However, many agents found 10mm recoil too harsh.

In 1990, Smith & Wesson and Winchester collaborated to create the .40 S &W – effectively a shortened, lower-pressure 10mm cartridge that fit in 9mm-sized pistols . It offered more power than 9mm and higher capacity than .45 ACP.

GLOCK was among the first manufacturers to produce pistols in .40 S&W, beginning with the G22 (full-size) and G23 (compact). The G23 quickly became a standard-issue firearm for law enforcement agencies across the United States .

Today, while many agencies have returned to 9mm due to advances in bullet technology, the .40 S&W remains a respected and effective defensive caliber. The G23 Gen5 MOS FS represents its most refined platform.

MOS Adapter Plate Compatibility

The MOS system includes adapter plates for the following optic footprints:

Note: The G23 MOS uses the same MOS system as other GLOCK Gen5 MOS pistols. A red dot sight significantly improves target acquisition speed and accuracy at distance .

Ammunition Recommendations

The GLOCK 23 Gen5 MOS FS performs reliably with all SAAMI-spec .40 S&W ammunition.

For practice: .40 S&W FMJ from S&B, Geco, Magtech, Fiocchi, or Federal. The GMB barrel handles all standard pressure loads without issue.

For defense: Premium hollow points such as Speer Gold Dot 165gr or 180gr, Federal HST 165gr or 180gr, or Hornady Critical Duty 175gr. The .40 S&W has a proven track record in defensive use.

For duty / law enforcement: Many agencies issue 165gr or 180gr bonded hollow points – these loads offer excellent penetration and expansion.

For training: Consider a .22lr conversion kit for affordable practice alongside your G23. However, .40 S&W ammunition generally costs more than 9mm but less than .45 ACP.

Holster note: The slide width of .40 S&W Gen5 models (27.5mm) is slightly wider than 9mm models. Please consider this when choosing your holster .
