Holosun 407k Problems


As someone deeply involved in the world of shooting, both as a gun enthusiast and a tactical shooter, my journey with the Holosun 407K X2 has been a blend of highs and lows. Initially, this optic sight’s small size, clear reticle, and simplicity drew me in. 

Its reputation for maintaining zero and being a trustworthy and long-lasting device with a sturdy frame capable of enduring cruel treatment and harsh environments led to high satisfaction initially.

However, I encountered the same drawbacks many users have noted over time. The quick battery drain and dim reticle often compromised my shooting experience.

Moreover, the incompatibility with certain holsters and issues with durability, like loose mounting clamps and broken lenses, could have been better. These issues made me question the reliability of the Holosun 407K X2 in critical moments.

Despite these challenges, I realized the importance of considering alternatives like the Trijicon RMR Type 2, Leupold DeltaPoint Pro, and Aimpoint ACRO P-1. These options cater to specific wants and needs and provide an appropriate solution for various firearms. 

Additionally, awareness of issues such as vortex viper problems can offer valuable insights when comparing different models. My experience taught me the value of conducting an extensive study and carefully weighing choices before purchasing. Ultimately, every shooter’s journey is unique, and finding the right optic is about balancing personal preferences with practical functionality.

Factors To Consider When Choosing A Sight:

Selecting the right optic sight involves more than just picking a well-known brand. It’s crucial to consider the intended use; whether for a rifle, shotgun, criminal justice, or self-defense, each scenario demands specific features.

For instance, a wider window might be better for quick target acquisition in dynamic environments, while an exact reticle is essential for competitive shooting to ensure better shots.

Financial constraints also play a significant role. It’s important to be realistic about how much you’re willing to spend. While some inexpensive options offer great results budget-wise, expensive sights with sophisticated features and better durability might be more suitable for rigorous use.

Lastly, personal preferences matter. The choice between larger or smaller windows, specific mounting setups, or reticle types should align with your comfort and effortlessness in usage. Always test different sights to find the one that feels right for you.

My Friends Feedback:

My avid shooter friend recently shared his experience with the Holosun 407k. He was initially excited about its compatibility with the chews plate and the ease of installing it using screws and an extractor pin. However, he needed help maintaining zero.

Despite using it on different firearms like the g17 and with various types of ammo, including 124gr Reloads, he noticed inconsistencies in POI (Point of Impact) while shooting prone.

He meticulously adjusted the elevation and windage, marking the settings with a pencil on the optic. Yet, the sight’s point of aim shifted, especially during handheld shooting, leading to shots veering left. Frustrated, he questioned if he was a bad shooter, but similar issues persisted even after the sight was dismounted and tightened again.

Switching to the 507k with a DPP titanium plate from Amazon improved the quality of his shooting experience, especially with its different reticle options, including the 32MOA rectile. His feedback underscored the Holosun 407k’s potential issues, particularly in maintaining consistent accuracy with a handgun.
