Question 1

Is the Glock 23 Gen4 suitable for concealed carry?

Accepted Answer

Yes, the Glock 23 Gen4 is widely regarded as one of the best compact handguns for concealed carry due to its ideal balance between firepower, size, and reliability. It is designed to offer users a powerful .40 caliber option in a compact platform that’s easy to conceal under everyday clothing or tactical gear.


 	
Compact Frame Size for Daily CarryThe Glock 23 Gen4 maintains a compact profile similar to the Glock 19, with a shorter grip and barrel that make it easy to carry without printing.

 	
Lightweight Yet PowerfulAt just 23.65 ounces (unloaded), the Glock 23 Gen4 delivers manageable weight for all-day carry while still chambering the more potent .40 S&W round.

 	
Rough Textured Frame for Secure GripThe Gen4's Rough Texture Frame (RTF) ensures that even when carried inside the waistband or in humid conditions, your grip remains firm and reliable.

 	
Modular Backstrap System for ComfortIt includes interchangeable backstraps that allow customization to your hand size, improving draw control and carry comfort over extended periods.

 	
Compatibility with IWB and AIWB HolstersThe firearm fits most major holster styles, including popular inside-the-waistband (IWB), appendix carry (AIWB), and hybrid holsters for maximum concealment.

 	
Balanced Muzzle Rise and RecoilThanks to the dual recoil spring system, follow-up shots remain accurate and controlled, which is critical in defensive encounters.

 	
Trusted by Off-Duty Law EnforcementMany off-duty officers choose the Glock 23 Gen4 as their go-to concealed firearm, underscoring its dependability in life-critical situations.

Question 2

What type of ammunition does the Glock 23 Gen4 use?

Accepted Answer

The Glock 23 Gen4 is chambered for .40 Smith & Wesson (S&W), a powerful intermediate cartridge commonly used in both law enforcement and civilian defensive applications. It is designed to feed, fire, and cycle reliably with high-quality factory-loaded .40 S&W rounds.


 	
Standard .40 S&W CartridgesThe firearm is designed to safely use standard-pressure .40 S&W ammo in both full metal jacket (FMJ) and jacketed hollow point (JHP) formats.

 	
Recommended Grain WeightsOptimal performance is typically achieved with 165-grain or 180-grain bullets, providing consistent expansion and penetration for defense or training.

 	
Avoid Reloads and Overpressure RoundsIt’s advised to avoid using reloaded ammunition or +P+ variants unless verified for safe use, as they can increase wear and compromise safety.

 	
Wide Availability.40 S&W remains widely available in most markets, both in bulk training loads and premium defensive rounds such as Federal HST, Speer Gold Dot, and Hornady Critical Duty.

 	
Ballistic VersatilityThe .40 S&W round offers more energy than 9mm and a flatter trajectory than .45 ACP, providing strong terminal performance in varied scenarios.

 	
Clean-Burning Ammunition PreferredUsing high-quality, clean-burning cartridges will reduce fouling and make post-use cleaning easier and faster.

Question 3

How does the recoil of the Glock 23 Gen4 compare to other calibers?

Accepted Answer

The recoil from the Glock 23 Gen4 is sharper than that of 9mm pistols due to the increased power of the .40 S&W round, but it is still very manageable for most shooters, especially with the enhancements introduced in the Gen4 platform.


 	
Dual Recoil Spring System Reduces Felt RecoilOne of the key upgrades in the Gen4 is the dual recoil spring, which helps absorb recoil force and improve control during rapid fire.

 	
Moderate to Snappy Recoil ProfileCompared to the Glock 19 (9mm), the Glock 23 has a more pronounced recoil impulse, though still easier to manage than larger calibers like .45 ACP or 10mm.

 	
Controllable for Experienced ShootersThose with moderate handgun experience typically adapt quickly to the Glock 23's recoil pattern and can maintain excellent accuracy.

 	
Grip Texture Enhances StabilityThe rough-textured frame ensures a non-slip grip even when hands are sweaty or gloved, aiding in recoil management.

 	
Recoil Management Improves with Proper StanceA proper two-handed grip and shooting stance significantly mitigate recoil and allow for faster, more accurate follow-up shots.

 	
Aftermarket Modifications AvailableAccessories like compensators or heavier guide rods are available to further reduce muzzle rise if desired.

Question 4

What are the key differences between Glock 23 Gen3 and Gen4?

Accepted Answer

While both generations are reliable and proven, the Gen4 introduces several meaningful upgrades that enhance comfort, recoil control, and modularity. These improvements make the Gen4 a more modern and user-friendly platform.


 	
Dual Recoil Spring AssemblyThe Gen4 features a dual recoil spring that reduces felt recoil and improves spring life compared to the single-spring Gen3 system.

 	
Interchangeable BackstrapsGen4 models come with multiple backstrap sizes, allowing shooters to customize the grip for hand size and reach to the trigger.

 	
More Aggressive Grip TextureThe Gen4 uses a rough textured frame (RTF) to improve grip retention, especially under wet or sweaty conditions — a significant upgrade over the smoother Gen3 surface.

 	
Reversible Magazine ReleaseThe magazine release button on the Gen4 is enlarged and reversible, providing enhanced ergonomics for both right- and left-handed users.

 	
Slightly Modified InternalsSome internal parts such as the trigger bar and recoil assembly differ, which can impact compatibility when using aftermarket parts.

 	
Improved Durability for Duty UseThe Gen4 was designed with high-round-count environments in mind, such as law enforcement training or tactical use, making it more resilient in the long term.

Question 5

Does the Glock 23 Gen4 come with night sights or are they optional?

Accepted Answer
