Details

Description

Small optic, bold dot: the Holosun HS407K-X2 Red Dot Sight is cut for the slim K-cut slides of pistols like the Glock 43X/48, and puts a 6 MOA red dot in the middle of that small window. On a carry gun that is the sensible trade — you want the dot there the moment the sight comes up, not a fine aiming point to go looking for.

How It Compares

Want the switchable circle-dot in the same subcompact body? That is the HS507K-X2. The same single dot with a green emitter is the HE407K-X2. New to dot sizing? Read what MOA means, then check your slide against our footprints guide.

Ideal For

  • The Glock 43X/48, and other subcompact K-cut slides
  • Defensive carry where speed comes before fine precision
  • Shooters who want a single dot with no menu behind it
  • Slim pistols that a full-size optic would swamp

  • 6 MOA red dot, open reflex, single reticle
  • 12 brightness settings — 10 for daylight, 2 for night vision
  • Shake Awake motion activation
  • Side-loading CR1632; up to 50,000 hours

Help & guidance

Product FAQs

Why does the HS407K-X2 use a 6 MOA dot on a carry optic?

A bigger dot is quicker to find under pressure. Smaller dots are the more precise choice at distance, which is not what this sight is for.

What is the Holosun K footprint on the HS407K-X2?

It is a modified Shield RMSc pattern used on subcompact slides. The HS407K-X2 is cut for slim K-cut slides such as the Glock 43X and 48.

Should I buy the HS407K-X2 or the HS507K-X2?

The HS407K-X2 is the single-dot version, while the 507K adds the switchable circle-dot. Both sit in the same subcompact body.

Is the HS407K-X2 night-vision friendly?

Yes, there are 12 brightness settings in total, 2 of them intended for use with night vision. The other 10 are daylight settings.

What reticle does the Holosun HS407K-X2 have?

It has a single 6 MOA red dot in an open reflex body, with no reticle menu. That puts the dot there the moment the sight comes up.

What battery does the HS407K-X2 take?

It takes one side-loading CR1632 battery rated for up to 50,000 hours. Shake Awake motion activation is also fitted.

Does the HS407K-X2 have shake awake?

Yes, the HS407K-X2 has Shake Awake motion activation. It runs on a side-loading CR1632 rated up to 50,000 hours.

What are the click values and travel on the HS407K-X2?

Windage and elevation adjust in 1 MOA clicks with plus or minus 30 MOA of total travel. That applies to both axes.

How big is the HS407K-X2 window?

The viewing window measures 0.58 by 0.77 inches, or 15 by 20 mm. The sight is 1x, parallax-free with unlimited eye relief.

What is the HS407K-X2 housing made from?

The housing is 7075 aluminium. It uses the Holosun K footprint, a modified Shield RMSc pattern.

What comes in the box with the HS407K-X2?

The box contains the Holosun HS407K-X2 red dot sight, mounting hardware and tool, and a CR1632 battery.

Is there a green version of the HS407K-X2?

Yes, the same single dot with a green emitter is the HE407K-X2. This version uses a red emitter.

How long will my HS407K-X2 take to arrive?

Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival. Checkout is secured by Shopify.
