Top .40 Caliber Glock Models Reviewed: Buyer's Guide

The .40 S&W caliber offers a balanced middle ground between the stopping power of the .45 ACP and the higher magazine capacity of the 9mm. Despite shifting ammunition trends, many shooters remain loyal to the .40 S&W cartridge. Glock continues to produce some of the most reliable .40 S&W handguns available today. In this guide, we'll highlight the best .40 caliber Glock models to help you choose the ideal handgun for your needs. 

Why Choose a .40 Caliber Glock?

The .40 S&W round hits harder than 9mm, but lets you carry more bullets than a .45 ACP. This balance works great for self-defense and police use. It makes a bigger hole than 9mm and kicks less than bigger calibers when fired.

Glock pistols in .40 S&W stand out for their toughness and simple design. These guns work in bad conditions and need little cleaning to keep running. The injection molded frame keeps them light but strong for everyday carry. The same trigger feel across different models makes it easy to switch between Glock sizes.

Detailed Reviews of Top .40 Caliber Glock Models

Glock 22

Police departments across America trust the Glock 22 as their top .40 S&W pistol. This full-size gun balances recoil and power just right. The larger frame helps spread out recoil forces. This design makes quick follow-up shots easier and more on target.

Most hand sizes fit the grip without problems. Newer models come with swappable backstraps for a better fit. The 4.5-inch barrel delivers tight groups even for shooters who practice just a bit. Hitting targets at distance is slightly easier thanks to the longer sight radius, though seeing them remains the same. 

The G22 holds 15 rounds in its magazine. Officers like having plenty of ammo without needing to reload. Home owners pick this gun for the same reason. The full-size design allows for a longer barrel. This extra length helps the .40 S&W bullet perform better.

Both Gen 4 and Gen 5 models are currently available. The newer Gen 5 offers improved ergonomics and a smoother trigger. For shooters interested in mounting a red dot optic, Glock provides an MOS variant compatible with most popular sights through appropriate adapter plates. These enhancements ensure the G22 remains up-to-date as firearm technology evolves.

Glock 35

The Glock 35 represents the performance-oriented option in the .40 S&W family with its extended 5.3-inch barrel. This longer slide creates a better balance in the hand, and extends the sight radius for improved accuracy potential. Competition shooters gravitate toward this model for its natural pointing characteristics and flat-shooting profile.

This pistol essentially takes the G22 platform and optimizes it for precision shooting. The added barrel length increases bullet velocity, improving terminal ballistics and flattening the trajectory. Muzzle flip feels reduced compared to shorter models, allowing for faster follow-up shots during rapid-fire strings.

The G35 truly shines when equipped with a red dot sight via the MOS system. This combination transforms an already accurate pistol into a targeting machine, especially valuable in competition settings. Though slightly heavier than other models, the weight distribution actually improves the shooting experience rather than hindering it.

Home defenders might find the G35's longer barrel beneficial for maximum performance from defensive ammunition. The increased velocity can improve expansion and penetration characteristics of premium hollow points. Its full-size grip accommodates all fingers comfortably, promoting proper control during high-stress situations.

Glock 23

The Glock 23 finds the sweet spot between firepower and portability as the compact offering in the .40 S&W lineup. Its dimensions strike an excellent compromise for those wanting substantial stopping power in a package suitable for daily carry. The grip remains large enough for a proper shooting grip while still concealing easily under normal clothing.

With a 4-inch barrel, the G23 retains good ballistic performance without the bulk of full-size models. This shorter barrel sacrifices only a small amount of velocity while significantly improving weldability. Shooters with average hand sizes can still get a full grip on the pistol, unlike with smaller subcompact models.

The 13-round capacity provides ample firepower for defensive scenarios without creating printing issues during concealed carry. Many law enforcement officers choose this model as their off-duty weapon, because it mimics the feel of their duty G22 while offering better concealability. This similarity allows for training consistency across platforms.

Available in multiple generations including the Gen 5 MOS, the G23 benefits from Glock's continued refinements in ergonomics and performance. The Gen 5 models feature improved barrels, better triggers, and no finger grooves for broader appeal. These updates make an already excellent platform even more shooter-friendly for both new and experienced gun owners.

Glock 27

The Glock 27 is the smallest pistol in Glock's .40 S&W lineup. It works great for deep concealment when you need to stay armed discreetly. This tiny powerhouse fits easily in pocket holsters or ankle rigs. You can carry it in places where bigger guns would show too much.

The G27 works just as well as its bigger brothers despite its compact size. Tests prove it handles many types of ammo without problems. The 3.5-inch barrel makes bullets fly a bit slower than from larger guns. Modern defense ammo still works great at these reduced speeds.

This small gun holds 9 rounds of potent .40 S&W ammo. Most people can only fit two fingers on the grip comfortably. Magazine extensions can fix this grip issue if needed. You must decide what matters more - easy hiding or better handling.

G27 owners love that they can use bigger G23 or G22 magazines as backups. You can carry the gun with its small factory magazine for best concealment. Larger magazines stay ready when you need extra shots. All Glocks work the same way, so switching between magazines feels natural.

Testing and Reliability

Each Glock model undergoes rigorous testing by professionals before making it to market. The testing protocol for these reviews included firing at least 500 rounds through each pistol at distances of 5 and 7 yards. Both FMJ practice ammunition and JHP defensive loads were used to evaluate reliability across ammunition types.

Reviewers found all four Glock models maintained the brand's reputation for reliability. Malfunctions were exceedingly rare across all platforms, with most testers reporting zero failures in their test sessions. Accuracy proved consistent with expectations for each barrel length, with the G35 naturally producing the tightest groups due to its longer sight radius.

Research data noted that recoil increased predictably as the pistol size decreased, with the G27 producing the most felt recoil and the G35 producing the least. This follows physics: larger, heavier frames absorb more recoil energy before transferring it to the shooter. The difference becomes most noticeable during rapid-fire strings, where smaller pistols require more skill to control effectively.

Buyer's Tips: How to Choose the Right Glock Model

Your primary use case should guide your choice of Glock model. For home defense or duty use where concealment isn't necessary, the G22 or G35 makes the most sense. Their larger frames improve shootability and capacity. The G35 particularly suits those interested in competition shooting or maximum accuracy.

Concealed carriers should focus on the G23 or G27 depending on their clothing style and body type. The G23 works well for those who typically wear jackets or untucked shirts. The G27 serves those needing deep concealment or wearing tight-fitting clothes. Consider your hand size too; smaller hands may struggle with full-size grips, while larger hands might find subcompacts uncomfortable.

Generation choice matters when selecting a .40 S&W Glock. Gen 3 models offer proven reliability and the most aftermarket support. Gen 4 adds interchangeable backstraps and improved recoil systems. Gen 5 features the best factory triggers and barrels but commands higher prices. MOS versions cost more but provide significant value for those planning to add red dot sights. Note that buying MOS options saves you money in the long run, if you would eventually want to try optics on pistols down the road. 

Accessories and Customizations

Holsters represent the most important accessory purchase for your Glock. Kydex options provide excellent retention and durability for outside-the-waistband carry. Leather holsters offer comfort for all-day wear. Hybrid designs attempt to combine these benefits. Match your holster to your specific Glock model for proper fit and retention.

Sights deserve early consideration, as factory plastic sights satisfy few shooters. Night sights with tritium inserts improve low-light capability. Fiber optic sights enhance daylight visibility. Red dot optics mounted to MOS slides or aftermarket cut slides provide the fastest target acquisition but require practice to master.

The aftermarket support for Glock pistols exceeds almost any other handgun platform. Triggers, barrels, slide covers, magazine extensions, and internal parts all come in countless variations. Focus first on reliability-preserving upgrades like sights and grips before considering internal modifications. Extensive modifications may affect reliability, so test thoroughly after any changes.

Conclusion

The perfect .40 caliber Glock depends entirely on your specific needs and preferences. Full-size models deliver better shooting characteristics and capacity at the cost of concealment. Compact and subcompact models prioritize portability while sacrificing some shootability and capacity.

All four models maintain Glock's legendary reliability and simplicity of operation. The consistent manual of arms across the lineup means skills transfer seamlessly between models. This allows owners to choose the right tool for each specific scenario while maintaining training consistency.

Take time to handle and, if possible, shoot different models before purchasing. The feel in your hand matters more than specifications on paper. With proper selection and training, any of these .40 caliber Glocks will serve faithfully for years to come, whether for competition, home defense, or everyday carry.
