The Glock 22 in .40 S&W is one of the most widely distributed full-size service pistols in North American field use. Its full-size frame, 15-round capacity, and .40 S&W cartridge make it a capable field hunting sidearm and a practical carry pistol for outdoor professionals.
The factory plastic sights are the one component that Glock engineers left for aftermarket improvement. They are adequate for training and basic field work but are not the sight system a hunter or field carrier should run when the situation demands confident performance in low light.
The Glock 22’s standard dovetail cuts accept the most supported aftermarket sight ecosystem in the pistol market. The selection below covers iron sight upgrades and precision options suited to the .40 S&W’s field applications, with each evaluated on the specific performance requirements of a full-size service pistol used for hunting and outdoor carry.

1. Trijicon HD XR Night Sights – Best Overall
The Trijicon HD XR for the Glock 22 brings the same three-tier aiming system that dominates the law enforcement night sight market to the .40 S&W platform. The XR designation’s taller front post is relevant on the Glock 22’s full-size slide where the longer sight radius amplifies the precision advantage of a clean front sight acquisition.
The Glock 22’s .40 S&W recoil is sharper in character than 9mm, with heavier hunting loads. The Trijicon HD XR’s front post is robust enough to handle the heavier recoil impulse without sight shift over extended use.
The orange photoluminescent ring charges in ambient light and produces a large, visible aiming reference in the partial light of dawn and dusk. At full darkness the tritium vial takes over. The blacked-out rear with its serrated face eliminates glare and keeps the shooter’s focal plane on the front element.
On the Glock 22’s full-size frame the HD XR sight radius amplifies the precision advantage of the clear front-focused sight picture. At 25 yards in good light the Glock 22 with HD XR sights is capable of precise, accurate shot placement that the factory plastic sights cannot support at the same confidence level.
The Trijicon HD XR is the best sight upgrade for a Glock 22 used as a hunting sidearm or field carry pistol. The .40 S&W cartridge makes the Glock 22 a capable field weapon for medium game at close range, and the HD XR’s low light performance matches that capability across the full hunting day. Trijicon limited lifetime warranty. The single most effective upgrade available for a Glock 22 intended for serious field use.
Pros
- Orange ring provides the fastest, most reliable front sight acquisition in every light condition
- Blacked-out rear forces front sight priority for consistent, precise aiming
- Glock 22’s full-size sight radius amplifies the HD XR’s precision advantage over shorter pistols
- Robust front post handles the Glock 22’s sharper .40 S&W recoil impulse over extended use
- Trijicon vial quality is the industry benchmark for brightness and longevity
- Trijicon limited lifetime warranty
Cons
- Premium price tier for iron sights
- Blacked-out rear eliminates rear-illuminated redundancy for partial-light two-dot users
- Taller XR post requires holster clearance check for fitted duty holsters
2. Ameriglo Spartan Night Sights – Best Speed Accuracy Balance
The Ameriglo Spartan is designed around the principle of a front-focused sight picture that is faster than a traditional three-dot without sacrificing the precision reference that the Big Dot’s round front eliminates. The Spartan uses a tritium front with a white photoluminescent ring and a deep, sharp-edged Spartan-notch rear that frames the front post .
On the Glock 22’s full-size frame the Spartan’s wider rear notch improves first-light acquisition speed over a standard narrow notch while retaining the precision reference of a post-and-notch design.
In low light the white photoluminescent ring provides a large, visible front aiming reference between the photoluminescent limits of the TruGlo green ring and the Trijicon orange ring. The Spartan-notch rear is blacked out and provides a wide, clean frame for the front post without a rear tritium element competing for the shooter’s attention.
At 20 yards in field conditions the Spartan delivers a fast, accurate sight picture that covers the Glock 22’s practical field use distances with confidence.
The Ameriglo Spartan is the most balanced speed-and-precision night sight on this list for a Glock 22 used across multiple field applications. The wider notch accelerates first sight acquisition, the white ring is visible in every light condition, and the precision reference is retained for deliberate shots at 25 yards and beyond. One year warranty. A strong mid tier option for the .40 S&W field carrier.
Pros
- White photoluminescent ring provides a large, visible front reference in partial light
- Spartan notch rear is wider than standard for faster first-light acquisition
- Blacked-out rear maintains front sight focus priority
- Speed-precision balance covers both fast field and deliberate precision applications
- Mid tier price for tritium-equipped performance
Cons
- White ring is less visible than Trijicon’s orange in direct sun and low contrast backgrounds
- One year warranty is limited relative to Trijicon’s premium coverage
3. XS Sights DXT2 Big Dot – Best for Fast Field Acquisition
The XS DXT2 Big Dot on the Glock 22 is the most direct close-range hunting sidearm sight configuration on this list. The .40 S&W cartridge at 10 yards on a coyote, hog, or bear that has entered the hunter’s safety margin is the scenario the Big Dot was designed for.
From the draw to a hit on the critical zone at 7 to 10 yards, the Big Dot front is faster than any traditional sight design.
The Glock 22’s full-size frame and longer sight radius are not the primary advantage of the Big Dot configuration; this sight excels at speed, not precision.
For hunters who carry a Glock 22 as a backup for close encounters rather than a primary hunting sidearm for deliberate shots, the DXT2 is a straightforward answer.
The Big Dot’s large tritium insert is visible in near-darkness without a sight search. The V-notch rear keeps all focal attention on the front. In a genuine close-range field emergency scenario, the DXT2 is the fastest sight configuration available for a reliable hit.
At 25 yards the Big Dot bead covers significant target area and the sight picture becomes imprecise for deliberate, fine-placement shots. This is the design’s consistent limitation.
The DXT2 Big Dot is the right sight choice for any Glock 22 carried as a close-range backup hunting sidearm where speed of first shot is the overriding priority and deliberate precision beyond 15 yards is not a primary requirement.
For a Glock 22 used as a primary hunting pistol at varied distances, the Trijicon or Ameriglo options are better answers. One year warranty. The most direct answer for the close-range field backup application.
Pros
- Fastest iron sight to a hit at close range in any light condition
- Large tritium insert is visible in near-darkness without deliberate sight search
- V-notch rear removes rear from the aiming focus
- Purpose-built for the close-range field emergency scenario
Cons
- Large front bead covers target area at 25 yards
- Not suitable for the Glock 22 hunter who makes deliberate longer range shots
- One year warranty is basic coverage
4. TruGlo Tritium Pro Night Sights – Best Value
The TruGlo Tritium Pro for Glock delivers the luminescent ring concept at the most accessible price on this list. For a Glock 22 owner who needs a genuine tritium upgrade over factory sights without a premium investment, the Tritium Pro covers every field carry scenario with the luminescent ring advantage over bare-vial options.
The green ring is visible as a large, glowing reference in partial light before the tritium vial is needed at full darkness. The two-dot rear provides a low light reference without blacking out.
In field low light conditions the TruGlo Tritium Pro delivers a usable, reliable sight picture from the gray pre-dawn through full darkness. The luminescent ring extends effective field performance into the partial light margins where a bare-vial tritium sight would require the shooter to work harder to locate the front.
At 20 yards in field conditions the two-dot rear and glowing front provide a consistent aiming reference for practical hunting pistol distances. In bright daylight the green ring is visible against most field backgrounds.
The TruGlo Tritium Pro is the right choice for the Glock 22 field carrier who wants a genuine tritium upgrade at a practical price. The luminescent ring provides real performance above bare-vial standards, and the two-dot rear covers low-light alignment for shooters who prefer the traditional three-dot reference with front sight priority. One year warranty. The best value night sight on this list for the Glock 22 field user.
Pros
- Luminescent ring provides genuine partial-light performance above bare-vial tritium
- Value tier pricing for a full tritium night sight upgrade
- Two-dot rear provides low-light reference for standard sight picture users
- Glock dovetail fit is correct for standard installation
Cons
- Tritium vial brightness is below the Trijicon premium level
- Two-dot rear requires front sight focus discipline to avoid divided attention
- One year warranty is basic coverage for a field carry sight
5. Meprolight FT Bullseye Rear Sight – Best Single-Element Rear Upgrade
The Meprolight FT Bullseye is a unique rear-only sight upgrade that replaces the standard Glock rear with a large tritium-filled ring that frames the front sight when aligned . The shooter looks through the Bullseye ring, centers the front sight inside it, and fires. No rear notch, no dots to align.
On the Glock 22 the Bullseye rear can be paired with the stock or upgraded front sight. For hunters who have a strong front sight index and find the traditional rear notch slow to locate in field conditions, the Bullseye rear provides a distinctive and fast alternative.
In low light the large tritium ring of the Bullseye rear is visible as a glowing circle. Centering the front sight within the ring is intuitive and fast once the technique is learned. In bright daylight the ring remains visible as a large, open circle frame.
The FT Bullseye’s primary limitation is at distance: centering a front post inside a large ring provides less precise windage reference than a tight rear notch at 25 yards and beyond.
The Meprolight FT Bullseye is a different sight approach that earns its place for Glock 22 shooters who have found the traditional rear notch to be the slow point in their sight acquisition sequence. It is not a sight for every shooter, but for the hunter who has trained with the concept and finds it faster, it delivers both low light utility and a distinctive field advantage.
One year warranty. The most unconventional and fastest rear upgrade on this list.
Pros
- Tritium-filled rear ring is visible in low light without a search
- Circle-and-post aiming system is intuitive and fast once trained
- Eliminates the rear notch location step from the sight acquisition sequence
- Distinctive field advantage for shooters who align with the concept
Cons
<ul>
- Requires adaptation and dedicated range time before field deployment</
li></li>
- Less precise windage reference at 25 yards compared to a tight notch rear</
li></li>
- Not compatible with all front sight heights; verify compatibility before purchase</

6. Glock OEM Adjustable Rear Sight – Best for Precision Field Work
The Glock OEM adjustable rear sight provides elevation and windage adjustability for a Glock 22 used with specific hunting loads that require point of impact tuning. For a hunter who carries a .40 S&W Glock 22 as a primary hunting sidearm with a single consistent load and wants a tuned point of impact at a set field distance, the OEM adjustable rear provides that capability.
The adjustable rear pairs with the standard or upgraded front sight. For daylight precision field use where low light is not a primary concern, the adjustable rear provides the most precise aiming system on this list.
The OEM adjustable rear is a simple black notch with windage and elevation screws. In good field light it provides a clean, precise sight picture for deliberate aimed fire. Once set for a specific load at a specific distance it holds the adjustment through normal field use.
In low light the non-illuminated rear provides minimal guidance, which limits the OEM adjustable rear to daylight hunting applications.
The OEM adjustable rear is the right component for any Glock 22 hunter who prioritizes precise point of impact for a specific hunting load over low light capability. For a .40 S&W sidearm used at known distances with a consistent load, the adjustability is a genuine hunting advantage. It is not a night sight and is not the right choice for a Glock 22 expected to perform in low light field carry situations. OEM warranty. A specific tool for a specific precision hunting application.
Pros
- Windage and elevation adjustability for precise load-specific point of impact tuning
- Most precise sight picture in good daylight of any option on this list
- OEM fit guarantees correct Glock slide compatibility
- Practical for a hunting sidearm used with one consistent load at known distances
Cons
- No low light capability; not suitable for field carry in variable light conditions</li>
- Adjustment screws can shift under hard use without periodic verification</li>
- Not
- a complete night sight solution; front sight upgrade also required for low light work</
- li>
Glock 22 Sight Configurations
Factory plastic sights
At dusk in a field setting the factory plastic sights are difficult to locate against a dark background. The white outlines provide minimal ambient light reference. In field conditions after the sun drops below the tree line, the factory sights create a real aiming reference problem that the hunting sidearm carrier does not want to discover in a genuine field scenario.
Standard three-dot tritium (TruGlo / Meprolight)</strong>
The luminescent ring and tritium vials provide a usable, reliable sight picture at full darkness. The front-focused priority requires training but is achievable. The primary limitation is the tendency to align all three dots rather than focusing on the front, which adds a fraction of a second to precise first shot placement. In a hunting field scenario that fraction is often irrelevant.
Orange ring, blacked rear (Trijicon HD XR)
The fastest to a precise hit in every light condition on this list. The orange ring is identifiable as the aiming element from the draw, the blacked-out rear keeps the shooter’s focus forward, and the tritium vial glows at full darkness. For any Glock 22 used in genuine field carry situations where low light performance is a real requirement, this is the configuration that earns its investment.
Big Dot (XS DXT2)
The fastest to any hit at close range. If the shooting distance is inside 15 yards and the requirement is a fast, reliable first hit, the Big Dot is the most direct path to that outcome. Past 20 yards the precision tradeoff becomes meaningful.
Field Notes: Glock 22 Sight Selection
<strong>The .40 S&W’s recoil sharpness affects sight picture recovery
The Glock 22’s .40 S&W recoil is sharper in character than 9mm, which means the front sight leaves the aiming picture more after each shot. A sight configuration that is fast to reacquire after recoil, a large, bright front element like the Trijicon orange ring, is a genuine advantage on the .40 S&W platform that is less critical on a 9mm pistol.</p>
Glock’s sight ecosystem is the widest available for any handgun
The Glock 22 accepts every aftermarket sight on this list and dozens of additional options without special fitting or machine work.
Any competent gunsmith can install any of these sights in under an hour. The most common installation error is an torqued rear sight that shifts under recoil, which is avoided with correct set screw torque per the manufacturer’s specification.
The Glock 22 as a hunting sidearm is a .40 S&W capability question
The .40 S&W with appropriate expanding hunting loads is a capable short-range field cartridge for coyotes, feral hogs, and defensive use against bear at close range.
At the distances where a sidearm is relevant in a hunting scenario, 10 to 25 yards, every tritium sight option on this list produces an accurate hit capability that matches the cartridge’s terminal performance. Match the sight to the specific scenario rather than the theoretical maximum capability.</p>
Final Thoughts
For the Glock 22 used as a field hunting sidearm in variable light conditions, the Trijicon HD XR Night Sights are the iron sight configuration that best matches the platform’s capability. The orange ring’s partial light performance, the blacked-out rear’s front sight discipline, and Trijicon’s premium vial quality combine to make this the most reliable sight system for a full-size .40 S&W pistol in genuine field use.
For hunters who want genuine tritium performance at a practical investment, the TruGlo Tritium Pro covers every field carry scenario with the luminescent ring advantage.
Match your sight selection to the distance and light conditions where your Glock 22 earns its carry, run the configuration under range conditions that simulate your field scenarios, and the G22 will deliver every shot it is capable of making.
