Ameriglo Night Sight .200 for Gen 5 Glock

Product Description

The Ameriglo Night Sight .200 for Gen 5 Glock is a replacement sight set engineered for fifth-generation Glock pistols, using tritium inserts for visibility in low light and darkness.

Night sights address the primary limitation of factory polymer sights: they’re invisible when ambient light drops. Tritium vials glow continuously without batteries or external charging, making sight alignment possible in dim parking garages, during early-morning hours, or anywhere light is limited.

The .200″ front height designation tells you how tall the front sight post measures, which affects point of impact and co-witness with optics. Shooters replace sights to correct holdover issues, to pair with suppressor-height red dots, or simply to upgrade from factory plastic to a more durable metal construction with self-illuminating dots.

What Makes Gen 5 Glock Sights Different

Gen 5 Glock models introduced a slightly revised sight dovetail dimension and a front sight that no longer uses a hex screw. If your Glock has the Glock Marksman Barrel and lacks finger grooves on the grip, it’s Gen 5. Trying to install Gen 3 or Gen 4 sights on a Gen 5 slide will result in fit problems or damage.

Ameriglo manufactures sights with dovetail cuts specific to each Glock generation. This set is cut for Gen 5 slides only. If you’re unsure which generation your pistol is, call 817-393-4000 and we’ll help you confirm before you order.

Understanding the .200″ Front Height

Front sight height controls where your rounds land relative to your point of aim. A .200″ front post is considered standard height for most Glock applications and pairs with standard-height rear sights to maintain the factory zero.

If you plan to mount a red dot or reflex optic on your slide, you may need suppressor-height sights instead, which sit taller and remain visible in the lower third of the optic window. Standard-height sights like this .200″ set work best on pistols that will remain iron-sight only or that use an optic mounted forward of the slide.

How Night Sights Work

Tritium is a radioactive isotope that emits beta particles, exciting a phosphor coating inside a sealed glass vial. The result is a soft glow visible to the naked eye in darkness. No switches, no batteries, no need to expose the sight to light before use.

Tritium has a half-life of about twelve years, meaning the brightness diminishes slowly over time. Most shooters find night sights remain usable well beyond that point, though the glow will be dimmer than when new. The metal sight bodies remain fully functional even after the tritium dims, so you’re left with high-visibility sight dots during daylight and a durable steel or aluminum sight either way.

Frequently Asked Questions

Q: Will Ameriglo Gen 5 Glock night sights fit my Gen 4 or Gen 3 Glock?

A: No, Gen 5 Glock sights use a different dovetail specification and will not fit earlier generations. You need sights specifically cut for Gen 3, Gen 4, or Gen 5 depending on your pistol’s generation. If you’re uncertain which generation you own, call 817-393-4000 and we’ll walk you through identifying your slide.

Q: What does the .200″ measurement mean on this Ameriglo sight?

A: The .200″ refers to the height of the front sight post, measured from the bottom of the dovetail to the top of the sight. This dimension affects your point of impact and determines whether the sight will co-witness with slide-mounted optics. Standard-height sights like .200″ work for irons-only setups or with frame-mounted optics.

Q: Do I need a gunsmith to install Glock Gen 5 night sights?

A: Many shooters install Glock sights at home using a sight pusher tool and a front sight tool, but the dovetails are tight and it’s easy to mar the slide or break a sight if you’re unfamiliar with the process. Western Sport offers installation services in Roanoke. Call 817-393-4000 to schedule gunsmithing work or to ask about the tools required for a home install.

Q: How bright are Ameriglo tritium night sights in total darkness?

A: Tritium sights glow brightly enough to see the three dots clearly in total darkness, allowing you to align your sights without any ambient light. The glow is not a flashlight—it won’t illuminate your target—but it makes the sights themselves visible so you can establish a sight picture. Brightness fades gradually over the tritium’s half-life, typically around twelve years.

Q: Can I use these sights with a red dot mounted on my Gen 5 Glock slide?

A: It depends on the height of your optic mount. Standard .200″ height sights will likely sit below the window of most slide-mounted red dots, making them difficult or impossible to see. If you want backup irons visible through the lower portion of your optic, you need suppressor-height or co-witness-height sights instead. Call 817-393-4000 to confirm the right height for your optic setup.

Q: Does Western Sport ship Ameriglo sights or do I need to pick them up in Roanoke?

A: Western Sport handles both shipping and in-store pickup for iron and night sights. Sights are not regulated items, so they ship to your door without an FFL transfer. If you’re local to the DFW area, you’re welcome to pick up your order at our Roanoke location and ask our gunsmith about installation while you’re here. Call 817-393-4000 with questions.
