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

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.
