Choosing the Best Sight for Your Glock 19: A Buyer’s Guide
Upgrading the sights on your Glock 19 is one of the best things you can do to improve your shooting. Stock sights are okay, but new sights make hitting targets much easier and faster. This guide helps you pick the perfect set.
Key Features to Look For
When shopping for new Glock 19 sights, look closely at these important features. They make a big difference in how well you shoot.
1. Sight Type
- Iron Sights: These are the standard sights, just better. They come in three main styles: standard, high visibility (often with bright dots), and night sights.
- Red Dot Sights (Optics): These small electronic scopes sit on top of the slide. They show a single glowing dot for aiming. They offer the fastest target acquisition.
2. Visibility and Contrast
Good sights need to stand out against the target. Look for sights with bright colors, like a large orange front dot or three glowing tritium dots (for night use).
3. Durability and Construction
Your sights need to handle recoil and daily carry. Check what they are made of. They must resist bumps and drops without moving out of alignment.
Important Materials Matter
The material used to make the sights directly affects how long they last and how clear they look.
Metal Sights
- Steel: This is the toughest material. Steel sights handle heavy use very well. They are common for high-quality iron sights.
- Aluminum: Lighter than steel, aluminum is often used for budget or lighter optic mounts. It is strong but can sometimes dent if hit hard.
Luminous Materials (For Night Use)
- Tritium: This radioactive gas glows brightly in the dark for many years. Tritium night sights are excellent for low-light defense.
- Fiber Optic: These sights use thin plastic tubes that grab any available light, making the front sight appear very bright during the day.
Factors That Improve or Reduce Quality
Not all sights are built the same. A few details can make your sights much better—or much worse.
Quality Boosters
- Machining Precision: Tightly made sights stay zeroed (keep their aim) even after many shots. Poorly made sights might shift alignment.
- Glare Reduction: Many quality iron sights have matte or serrated rear blades. This stops sunlight from reflecting into your eyes, keeping the sight picture clear.
- Mounting System (for Red Dots): If you choose an optic, make sure the mounting plate is solid and fits your specific Glock 19 model perfectly.
Quality Reducers
- Plastic Components: Avoid sights that use a lot of plastic, especially for the mounting or the sight housing. Plastic breaks easily under the stress of shooting.
- Weak Finish: A poor finish can chip or rust. Look for durable coatings like nitride or hard anodizing.
User Experience and Use Cases
Think about where and how you use your Glock 19. This helps narrow down your choice.
Self-Defense and Home Protection
For quick, close-range defense, night sights or a fast red dot are best. You need to see the sights instantly in the dark. Fiber optic front sights also work well here because they are very fast to pick up in daylight.
Range Shooting and Competition
Competitors usually want the fastest sight picture possible. This often means a large, bright front sight or a quality red dot optic. The focus is on speed and accuracy over long strings of fire.
Concealed Carry (CCW)
If you carry concealed, you need sights that won’t snag on clothing. Smooth, low-profile iron sights are great. If you use a red dot, make sure the housing is rounded and snag-free.
10 Frequently Asked Questions (FAQ) About Glock 19 Sights
Q: Do I need special tools to install new Glock 19 sights?
A: Yes, most iron sights require a sight pusher tool to safely remove and install them without damaging the slide. Red dots require screwdrivers for mounting.
Q: Are night sights better than fiber optic sights?
A: Night sights glow in total darkness using tritium. Fiber optics need some light to glow brightly during the day. Night sights are better for low-light defense; fiber optics are often faster in bright light.
Q: Can I put a red dot on a standard Glock 19 slide?
A: Not usually without modification. You must have a slide that is “optics ready” (comes with a cutout) or you must send your slide to a gunsmith to have a mounting plate milled into it.
Q: How long do tritium night sights last?
A: Tritium gas remains visible for about 10 to 12 years before it starts to dim noticeably. Many manufacturers offer lifetime warranties on the tritium itself.
Q: Will new sights affect my gun’s accuracy?
A: Yes, if they are installed correctly. The rear sight must be perfectly aligned with the front sight. A gunsmith should “zero” your new sights after installation.
Q: What is “co-witnessing” when talking about red dots?
A: Co-witnessing means you can see your iron sights through the window of your red dot optic. This is a backup sight system in case your red dot battery dies.
Q: Are budget sights a bad idea for self-defense?
A: Budget sights often use softer materials and lose their zero (alignment) easier. For a defense gun, spending more on quality steel sights is usually safer.
Q: What does “serrated rear blade” mean?
A: This means the back of the rear sight has small, sharp grooves cut into it. These grooves help stop sunlight from bouncing off the rear sight and confusing your eye.
Q: Should I choose sights taller than stock sights?
A: If you plan to add a red dot later, you might want slightly taller iron sights. This lets you see the iron sights through the optic window (co-witnessing).
Q: How often should I check the tightness of my sights?
A: Always check them after a heavy shooting session. Once they are zeroed, check them every few months during regular cleaning.
