The Glock 22 ships with plastic sights.
That is not a knock on Glock’s engineering priorities. The pistol is built to be a reliable, durable duty gun at a competitive price, and plastic sights keep that price reasonable.
But plastic sights break, fade, and scratch in a way that quality aftermarket options do not. Every serious Glock 22 owner replaces them.
The Glock 22 is a .40 S&W duty pistol.
It has been the most issued law enforcement sidearm in the United States for decades, chambered in a cartridge that hits harder than 9mm but fits in the same frame size as a full-size service pistol.
The sight choice for a duty gun differs from a range toy: durability under hard use, performance in low light, and robustness to patrol conditions matter as much as target accuracy.
Sight options for the Glock 22 span three categories.
Fixed iron sights: tritium night sights, fiber optic, or blacked-out tactical. Adjustable iron sights for precision range work. And optics-ready setups using a red dot with appropriate backup sights.
The Glock 22 uses standard Glock sight dimensions.
The front sight post is the standard Glock dovetail and the rear is the standard Glock rear dovetail, which means the enormous aftermarket for Glock pistol sights applies to the 22 without modification.
These five picks cover duty, carry, range, and optic-equipped applications.

#1 Trijicon HD XR Night Sights – Best Overall
The Trijicon HD XR Night Sights are the standard by which duty pistol night sights are measured.
They solve the core problem of duty gun sighting in one coherent design: visible in daylight, visible in low light, and durable enough to handle years of holster wear, training, and patrol use without degrading.
The orange photoluminescent outline around the tritium front vial is the defining feature.
In daylight the orange ring draws the eye to the front sight faster than a plain black post or a green tritium vial alone.
In true darkness the tritium takes over. The result is a front sight that is fast and visible across the full range of lighting conditions a duty gun encounters.
The rear sight is a black serrated tritium unit.
The serrations reduce glare in bright conditions. The tritium dots at the rear are smaller and less bright than the front, which is intentional: the rear sight should register without competing with the front for the shooter’s attention.
The steel construction handles the hard use that a duty Glock 22 encounters.
Holster wear, vehicle carry, and the repeated cycling of training do not degrade the Trijicon HD XR over time.
The tritium vials are rated for 12 years of glow, which covers a typical police service pistol’s issue lifetime.
Key Features
| Feature | Specification |
|---|---|
| Front Sight | Tritium with orange photoluminescent outline |
| Rear Sight | Tritium, black serrated |
| Construction | Steel |
| Tritium Life | 12 years |
| Fit | Standard Glock dovetail |
Pros
- Orange outline front is the fastest day/night combination in a fixed duty sight
- Steel construction handles years of duty carry and hard use
- Front-rear brightness balance keeps focus on the front sight
- 12-year tritium rating covers a full service pistol lifespan
Cons
- Price is above basic iron sight options
- Tritium vials require factory replacement after 12 years
- Not adjustable for elevation or windage
Our Take
The Trijicon HD XR is the right duty sight for a Glock 22. The orange outline front, steel construction, and 12-year tritium rating cover every condition a law enforcement or duty-use Glock 22 encounters from day one.
#2 AmeriGlo Hackathorn Sights – Best for Carry
The AmeriGlo Hackathorn sights were designed in collaboration with firearms trainer Ken Hackathorn to address a specific carry pistol problem: the rear sight that catches on clothing during a draw.
The rear sight is flat-topped and serrated with no snag points.
It presents a clean, non-reflective rear notch that indexes under stress without giving a concealed carry draw anything to catch on.
The front sight is a tritium vial that gives low light visibility without the complexity of an orange-outline system.
The design philosophy is deliberate minimalism. Carry sights need to be snag-free, visible in low light, and simple enough to index under stress.
The Hackathorn sights deliver all three without unnecessary features.
The steel construction handles the wear of carry. For a Glock 22 used in a plainclothes law enforcement or duty carry role where the pistol lives in a holster and draws must be clean and fast, the Hackathorn sights are the purpose-matched choice.
Key Features
| Feature | Specification |
|---|---|
| Front Sight | Tritium |
| Rear Sight | Black, flat-top, serrated, snag-free |
| Construction | Steel |
| Fit | Standard Glock dovetail |
Pros
- Flat-top rear sight eliminates snagging on clothing during draw
- Tritium front provides low light visibility
- Minimalist design indexes under stress
- Steel construction handles carry wear
Cons
- No orange outline on the front for faster daylight acquisition
- Rear tritium is minimal compared to the Trijicon HD XR system
- Not the right choice for a range-focused or precision application
Our Take
The AmeriGlo Hackathorn sights are the right choice for a Glock 22 used in a concealed carry or plainclothes duty role. The snag-free rear and tritium front prioritize the two things that matter most for a carry gun: a clean draw and low light visibility.
#3 Dawson Precision Adjustable Rear / Fiber Optic Front – Best for Range
The Dawson Precision adjustable rear with fiber optic front is the right combination for a Glock 22 used for range work, competition, or precision training.
Fiber optic sights pull ambient light into a colored rod that creates a bright, visible aiming point in normal shooting conditions.
Under range lights or outdoor daylight, a fiber optic front is faster and more visible than any tritium sight in the same conditions.
The trade-off is performance in darkness, where fiber optic provides no active illumination.
The adjustable rear sight is the feature that earns its place on a range gun.
Glock 22 pistols often have point of impact variance between individual guns and individual loads.
An adjustable rear allows a shooter to dial the point of impact to match their specific combination of gun, load, and shooting distance.
On a duty gun fixed sights are the reliable choice for field conditions. On a range and competition gun the adjustable rear provides precision that fixed sights cannot. Dawson Precision machines these sights in the US to tight tolerances.
Key Features
| Feature | Specification |
|---|---|
| Front Sight | Fiber optic |
| Rear Sight | Adjustable, blacked-out |
| Construction | Steel |
| Fit | Standard Glock dovetail |
Pros
- Adjustable rear allows precise zero for specific loads and distances
- Fiber optic front is the fastest and most visible option in daylight range conditions
- US-machined steel construction to precise tolerances
- Ideal for competition shooters who need point of impact adjustability
Cons
- Fiber optic front provides no illumination in darkness
- Adjustable rear is more fragile than a fixed duty sight under hard field use
- Not the right choice for a duty or carry gun
Our Take
The Dawson Precision adjustable rear with fiber optic front is the right sight system for a Glock 22 used for range work, competition, or precision training. The adjustable rear and fiber optic front maximize what the pistol can do in optimal shooting conditions.
#4 Trijicon RMR Type 2 with Suppressor Height Sights – Best Red Dot Setup
The Trijicon RMR Type 2 is the standard by which pistol red dot sights are measured.
It has been adopted by US military special operations units, multiple law enforcement agencies, and more competition shooters than any competing red dot.
The housing is milled from 7075 aluminum and is the most impact-resistant pistol red dot available.
The 3.25 MOA dot size is the most versatile option for a duty Glock 22.
A smaller dot is more precise but slower to find under stress. A larger dot is faster to acquire but covers more of the target at distance. The 3.25 MOA split balances acquisition speed with precision for a duty pistol application.
The RMR Type 2 on a Glock 22 requires either a factory MOS slide or a milled slide from a quality gunsmith.
Suppressor height backup iron sights co-witness through the RMR’s window, providing a backup aiming system if the optic fails or the battery dies.
For a duty gun, backup irons are not optional when running a red dot.
The RMR’s battery compartment is accessible from the top without removing the optic from the slide, which allows battery replacement without losing zero.
Key Features
| Feature | Specification |
|---|---|
| Dot Size | 3.25 MOA |
| Housing | 7075 aluminum |
| Battery Life | Up to 4 years at setting 4 |
| Mount | RMR footprint (MOS or milled slide) |
| Backup Sights | Suppressor height required |
Pros
- Most impact-resistant pistol red dot available with proven duty track record
- Top-loading battery allows replacement without losing zero
- 3.25 MOA dot balances acquisition speed and precision for duty use
- Military and law enforcement adoption validates its field reliability
Cons
- Requires slide milling or MOS Glock for correct mounting
- Price is a significant investment above iron sight options
- Backup iron sights are an additional purchase requirement
Our Take
The Trijicon RMR Type 2 is the right red dot for a Glock 22 duty pistol where the optic must handle hard use, maintain zero, and never fail at a critical moment. Pair it with suppressor height backup sights and it is the most capable sighting system available for this pistol.
#5 XS Sights DXT2 Big Dot – Best for Fast Acquisition
The XS Sights DXT2 Big Dot is the fastest-acquiring iron sight design available for the Glock 22. The large tritium front dot is wider than any standard sight post.
In express sighting philosophy, which the Big Dot uses, the front sight is large enough that finding it is instantaneous under stress.
The shooter does not need to search for the sight under adrenaline. The large dot is already there.
The shallow V rear notch frames the front dot without requiring precise alignment.
The Big Dot philosophy accepts some sacrifice in precision at distance in exchange for maximum speed at close range.
For a duty or defensive Glock 22 where most shooting happens inside 15 yards under high stress, that trade-off is rational.
The tritium in the front dot provides low light visibility. The rear sight has a white line that provides a reference for the V notch in daylight.
This system is not appropriate for a precision range gun. It is designed for defensive and duty use where speed of first shot at close range is the priority.
Key Features
| Feature | Specification |
|---|---|
| Front Sight | Large tritium dot |
| Rear Sight | White stripe shallow V notch |
| Construction | Steel |
| Fit | Standard Glock dovetail |
Pros
- Fastest iron sight acquisition available on a Glock platform
- Large tritium front is visible and fast in all lighting conditions
- Shallow V rear does not require precise alignment for close range work
- Steel construction handles duty and carry use
Cons
- Precision at distances past 15 yards is sacrificed for speed
- Not suitable for competitive or accuracy-focused range use
- Express sighting system requires adjustment for shooters trained on conventional three-dot sights
Our Take
The XS Sights DXT2 Big Dot is the right choice for a Glock 22 owner who prioritizes close-range speed above all else. For duty and defensive applications where the first shot inside 10 yards is the primary concern, no iron sight acquires faster.
Did You Know? The Glock 22 in .40 S&W was developed in 1990 in response to FBI adoption of the 10mm Auto cartridge. The FBI found the full 10mm load too powerful for many agents, and the .40 S&W was created as a compromise: a shorter case with reduced powder charge that produced similar terminal ballistics in a cartridge that fit in a 9mm-sized frame. The Glock 22 became the most issued law enforcement pistol in the United States and held that position for over two decades.
Frequently Asked Questions: Best Sights for Glock 22
Do I need to replace the factory sights on my Glock 22?
Yes, if you use the pistol for duty, carry, or serious training. The factory plastic sights are adequate for casual range use but are not durable enough for sustained duty carry and do not provide low light visibility.
What is the best night sight for a Glock 22 duty pistol?
The Trijicon HD XR is the standard recommendation for duty use. The orange outline front and 12-year tritium rating cover every lighting condition a duty pistol encounters and hold up to years of field use.
Can I put a red dot on a standard Glock 22?
You need either a Glock 22 MOS model or a slide milled by a gunsmith. A standard Glock 22 slide does not have a mounting platform for a red dot. The MOS version has an adapter system; a milled slide provides a more direct mount.
What sight height is standard for the Glock 22?
The Glock 22 uses standard Glock sight dimensions. Most aftermarket Glock sights are compatible without modification. The front sight post uses a standard Glock front dovetail and the rear uses the standard Glock rear dovetail.
Are Glock 17 sights compatible with a Glock 22?
Yes. The Glock 17 and Glock 22 share the same sight dimensions. Any sight listed as compatible with the Glock 17 will fit the Glock 22 and most other full-size Glock pistols.
Verdict
The Glock 22 is a duty pistol that deserves duty-grade sights. The factory plastic is a starting point, not a permanent solution.
For a duty or law enforcement application, the Trijicon HD XR Night Sights are the right answer. The orange outline front, steel construction, and 12-year tritium rating are the standard for a reason.
For a carry or plainclothes duty gun where snag-free draw matters, the AmeriGlo Hackathorn sights are the purpose-matched choice.
The Dawson Precision adjustable rear with fiber optic front maximizes the pistol’s accuracy capability for range, competition, or precision training use.
For a complete duty optics upgrade, the Trijicon RMR Type 2 with suppressor height backup sights is the most capable sighting system available on this platform.
And for maximum close-range acquisition speed in a duty or defensive role, the XS Sights DXT2 Big Dot is the fastest iron sight available.
Upgrade the sights. The Glock 22 earns better than factory plastic.
