Holosun 407 Red Dot: Durable Waterproof Optic for P365X

When you need a compact, battle-ready optic for a subcompact pistol, durability and quick target acquisition are non-negotiable. We bring field-tested perspective and practical advice so you can choose an optic that performs when it counts—on the range, in training, and in safe defensive applications.

HOLOSUN 407

Key Features That Matter

HOLOSUN 407 is an open reflex sight engineered for subcompact pistol platforms. The HE407K-GR X2 variant improves on previous iterations by adding Lock Mode to prevent accidental changes to brightness or reticle settings—an important control for concealed-carry or training use. You get a crisp 6MOA dot powered by Holosun’s Green Super LED with up to 50,000 hours of battery life and the Shake Awake function that conserves power while staying ready when you need it.

Fit, Footprint, and Mounting

The 407 uses the Holosun K footprint and accepts a 1632 battery in a side-mounted tray for quick swaps without removing the optic. It’s a direct fit for P365X and P365XL slides; slides with a four-boss interface will require an adapter plate. If you run an X/XL or plan to adapt different slide interfaces, factor the adapter into your install plan and zeroing session.

Durability and Battery Life

Construction is forged from 7075 aluminum, giving the 407 a class-leading strength-to-weight ratio for a sight this small. IP67 waterproofing ensures the optic survives wet environments and adverse weather during training sessions. The side-mounted 1632 battery tray and long LED life mean low maintenance and fewer trips to the bench for battery changes.

Reticle and Sight Picture

The 6MOA green dot is bright and easy to pick up against most backgrounds. Green Super LED technology offers improved visibility in daylight and low-light conditions without overbearing bloom. For defensive drills, a 6MOA dot balances speed with precision—fast acquisition at close ranges while still allowing for effective sight placement inside vital zones.

Price and Practical Considerations

At $239.99, HOLOSUN 407 delivers features commonly found on higher-priced micro red dots: Lock Mode, Shake Awake, advanced LED life, and IP67 durability. For owners of the P365X/XL series or anyone running a K-footprint plate, it’s a practical upgrade that keeps your pistol slim and your sight picture clear.

Final Notes from Two Operators

We look for reliability, low weight, and intuitive controls. The HOLOSUN 407 brings Lock Mode, long battery life, and rugged 7075 aluminum construction into a compact package tailored for subcompact pistols. If you want a dependable micro reflex that pairs naturally with the P365X/XL footprint, this optic deserves a hard look.
