Why Glock 21 Suppressor Sights Are Necessary
From my experience, using suppressor sights on my Glock 21 has made a significant difference in both accuracy and safety. When attaching a suppressor, the standard sights often become obstructed or misaligned, making it difficult to aim properly. Suppressor sights are specifically designed to be taller, allowing me to see clearly over the suppressor without any obstruction. This ensures my shots are accurate every time, which is crucial whether I’m at the range or in a real-world situation.
Another reason I find suppressor sights necessary is the added durability and reliability they offer. With a suppressor attached, the firearm’s profile changes, and standard sights can sometimes get damaged or knocked out of alignment. Suppressor sights are built to withstand these challenges, giving me confidence that my Glock 21 will perform consistently without needing constant adjustments.
Overall, having suppressor sights has improved my shooting experience by providing clear sight pictures and maintaining sight integrity when using a suppressor. For anyone considering adding a suppressor to their Glock 21, I’d say these sights are an essential upgrade that enhances both functionality and peace of mind.
My Buying Guides on ‘Glock 21 Suppressor Sights’
When I first decided to upgrade my Glock 21 with suppressor sights, I quickly realized that choosing the right set is essential for both accuracy and durability. Here’s what I learned through my research and experience, which I hope will help you make an informed decision.
Understanding Suppressor Sights for Glock 21
Suppressor sights are designed to be taller than standard sights, allowing you to see over the suppressor without obstruction. For my Glock 21, which shoots .45 ACP, this meant finding sights that maintained a clear sight picture while withstanding recoil and harsh conditions.
Key Features I Looked For
- Height and Compatibility: The sights had to be tall enough to clear my suppressor but still fit the Glock 21 slide without modification. I checked manufacturer specs carefully to ensure compatibility.
- Durability: Since I use my Glock for both range practice and protection, I needed sights made from robust materials like steel or aluminum with a tough finish.
- Night Visibility: Tritium or fiber optic inserts were a must-have for low-light conditions. I personally prefer tritium for its glow in the dark, which doesn’t rely on ambient light.
- Adjustability: Being able to adjust windage and elevation allowed me to zero the sights perfectly after mounting the suppressor.
- Installation: I wanted sights that were easy to install with basic tools or even by myself without professional help.
My Top Considerations Before Buying
- Brand Reputation: I leaned towards brands known for quality Glock sights, like Trijicon, AmeriGlo, and XS Sights. They have proven track records and customer support.
- Sight Profile: Low-profile suppressor sights look sleek but might not clear every suppressor. Taller sights ensure no sight obstruction but can snag on holsters or gear. I balanced these factors based on my daily carry needs.
- Cost vs. Value: High-quality suppressor sights can be pricey, but I found that investing in reliable sights saved me money and frustration in the long run.
- Reviews and User Feedback: Reading user experiences helped me avoid brands with durability issues or poor fit.
Installation Tips From My Experience
I recommend using a sight pusher tool or having a gunsmith install the sights if you’re not comfortable doing it yourself. Applying a bit of blue thread locker on the screws helped keep them secure. After installation, I always re-zeroed my sights at the range, especially when shooting suppressed.
Final Thoughts
Choosing suppressor sights for my Glock 21 was about finding the right balance between function, durability, and ease of use. By focusing on compatibility, visibility, and build quality, I ended up with sights that enhanced my shooting experience and complemented my suppressor setup perfectly. If you take the time to consider these factors, you’ll be just as satisfied with your purchase as I am with mine.
