Description
The Holosun HS507K X2 Red Dot Sight is Holosun built the way a carry optic should be built. It is sized for sub compact and pocket pistols, it runs 50,000 hours on a battery you can change without pulling the sight off the gun, and it has a lock mode so nothing gets bumped while it rides in a holster. Part HS507K-X2.
Side Access Battery Tray Changes Everything
On most micro optics other than the Holosun HS507K X2 Red Dot, the battery lives under the sight. Changing it means unbolting the optic, swapping the cell, rebolting, and then confirming zero at the range because you just broke the mating surface between the sight and the slide.
The Holosun HS507K X2 Red Dot loads its high capacity lithium cell from the side. The sight never leaves the slide, the screws never move, and your zero never comes into question. On a carry gun that gets a fresh battery on a schedule, that difference adds up to years of not re-zeroing.
Lock Mode Is A Carry Feature, Not A Gimmick
A holstered optic gets pressed against a belt, a car seat, a jacket and a seatbelt all day long. Buttons get bumped. Brightness gets dialed to nothing, or the reticle gets changed, and you find out at the worst possible moment.
Lock mode on the Holosun HS507K X2 Red Dot disables the buttons entirely. Set your brightness and your reticle, lock it, and the optic stops listening until you tell it otherwise. It is a small feature that only matters to people who actually carry, which is exactly who this sight was designed for.
The Holosun HS507K X2 Red Dot Runs 50,000 Hours
Shake Awake on the Holosun HS507K X2 Red Dot senses motion and powers the sight on, then powers it down when the gun sits still. Last setting recall means it comes back exactly where you left it, same brightness and same reticle, with nothing to re-select.
Combine that with a 50,000 hour rating and the practical result is a sight you turn on once and then more or less forget about. Fifty thousand hours is over five years of continuous run time, and Shake Awake means you are nowhere near continuous. Change the battery on your birthday and get on with your life.
Three Reticles From One Emitter
The Multi Reticle System on the Holosun HS507K X2 Red Dot gives you a 2 MOA dot alone, a 32 MOA ring alone, or the ring with the dot inside it. The part that matters is that all three are projected from the same LED, so switching reticles does not move your point of impact and there is no re-zeroing.
That means you can run ring and dot for speed on a defensive gun, drop to the bare 2 MOA dot for a precision drill or a small target, and switch straight back with no consequences. Most owners of the Holosun HS507K X2 Red Dot settle on ring and dot and stay there, but the option costs you nothing.
Built For A Small Slide
The body is machined from 7075 T6 aluminum, the same alloy family used for rifle receivers, and the lens is multicoated for a bright, clean sight picture rather than the dim blue cast cheaper glass gives you. The window is deliberately wide for a sight this size, which is what makes the Holosun HS507K X2 Red Dot fast to pick up when you are presenting from concealment and the gun is not perfectly presented yet.

Check Your Slide Cut First
The Holosun HS507K X2 Red Dot uses the Holosun K footprint. Micro compact slides are not standardized the way full size ones are, so confirm your pistol is cut for a 507K or 407K pattern, or plan on the correct adapter plate. Manufacturer specifications are published at Holosun.
We are a family owned FFL dealer in Collegeville, Pennsylvania, and we will happily check a footprint with you before you spend the money. Have a look through the rest of our optics selection, or call and tell us what pistol you are mounting to.
