Why I Chose the Holosun 407 Reflex Sight
The first thing that stood out to me was the brand’s reputation for reliable and innovative optics. The HS407A3 combines durability, advanced features, and value, making it ideal for both casual shooters and professionals. The 3 MOA red dot reticle is precise without being too small or overwhelming.
Key Features That Matter
- Shake Awake Technology: One of my favorite features is the Shake Awake functionality. The sight powers on instantly when it detects motion and powers down when idle, saving battery life without me having to remember to switch it off.
- Battery Life: The HS407A3 boasts an impressive battery life, lasting thousands of hours on a single CR1632 battery. This was a huge plus for me since I hate worrying about frequent battery changes.
- Durability: Built with a rugged aluminum housing and rated IP67 for water and dust resistance, this sight held up well during outdoor shooting sessions in various weather conditions.
- Multiple Reticle Settings: The ability to switch between a 3 MOA dot, a 32 MOA circle, or a combination of both gave me flexibility depending on the shooting scenario.
- Easy Installation: The compact design and included mounts made installation straightforward. It fit perfectly on my pistol slide and was zeroed quickly.
What to Consider Before Buying
- Intended Use: I recommend thinking about how you plan to use the sight. For pistols and close to mid-range shooting, the 3 MOA dot is excellent. However, if you want longer-range precision, you might want to explore other options.
- Compatibility: Make sure your firearm supports the footprint of the Holosun 407. It’s designed mainly for pistol slides but can also fit some rifles with the right mount.
- Price vs. Budget: While the HS407A3 is competitively priced, it’s still an investment. I found it offers great value considering the features and build quality, but set your budget accordingly.
- Battery Availability: The sight uses a CR1632 battery, which is common but less so than CR2032. I keep spares handy to avoid downtime.
My Buying Tips
- Always buy from authorized dealers to ensure warranty coverage and genuine products.
- Pair the sight with quality mounts to maintain zero and reliability.
- Take time to practice with the sight in different lighting conditions to fully understand the reticle options.
- Consider adding anti-reflective lens coatings or covers if you’ll be shooting in bright sunlight.
