For professionals and informed firearms owners, a pistol optic must balance ruggedness, battery life, and intuitive controls. The right red dot reduces engagement time, resists environmental threats, and stays locked on zero through everyday carry and training cycles.

HOLOSUN 507 brings a full-sized open reflex platform to service pistols and plate-mounted setups. The HE507C-GR X2 variant improves on earlier models by adding Lock Mode to prevent accidental adjustments, and pairs Holosun’s Green Super LED with up to 50,000 hours of battery life.

Key features that matter

Lock Mode: Prevents inadvertent setting changes during carry or when drawing from a holster. This is a practical safeguard for duty and defensive use.

Green Super LED & 50k-hour battery life: The green LED offers high-visibility dot performance and, paired with the long-life 1632 battery (side-mounted tray for easy swaps), minimizes maintenance intervals.

Solar Failsafe & Shake Awake: The optic leverages ambient light to extend runtime while Shake Awake conserves power and restores illumination when movement is detected—great for daily carry profiles.

Multi-Reticle System: Choose reticle options to match sighting preferences and target-background contrasts without changing optics.

Construction and fit: Machined from 7075 aluminum, IP67 waterproof rating, and an industry-standard footprint make mounting straightforward and durable under harsh conditions. Priced at $271.99, it positions as a high-value option for a robust pistol optic.

Performance in real-world roles

Designed full-sized for pistol applications, the HOLOSUN 507 supports rapid target acquisition, especially in low-light situations where the green dot excels. The side-mounted 1632 battery tray allows quick field replacement without removing the optic from a slide-mounted adapter. IP67 waterproofing and 7075 aluminum construction ensure mission-ready durability whether on the range or in carry.

Buying considerations

When choosing an optic for defensive pistols, prioritize lockable controls, battery longevity, and mounting compatibility. The HE507C-GR X2’s Lock Mode, Solar Failsafe, Shake Awake, and industry-standard footprint address those priorities at a $271.99 price point.
