A lot of shooters and gun owners who purchased or built their handgun from the ground up us the tried and true three dot iron sight arrangement.  Many of us spend plenty time at the range attempting to achieve better shot placement.  While three dot iron sights are pretty good, the Holosun HE509T Powered Red Dot sight is almost guaranteed to help you improve your accuracy.

This pistol sized Holosun Red Dot Sight straightaway allows for a large field of sight and has those features which allow you to sight in quickly and acquire the target and the location you intend to hit.  What’s so neat about the Holosun HE509T is that the entire sight system is fully enclosed in Titanium housing and you know right from the get-go it’s a rugged, little thing, while including an RMR mount adapter plate.  Built to provide enhanced environmental protection and abrasion and shock protection, The HE509T Red Dot Sight protective housing stands head and shoulders above an open form reflex form factor.

The Holosun HE509T Red Dot Sight uses Solar Failsafe™ technology to power the optic providing the shooter or operator with a consistent, and very reliable point of aim.  Another feature you simply don’t expect with a lithium powered optic sight such as this is you don’t have to worry about turning it on or forgetting to turn it off.

The Holosun Red Dot Sight uses patented Shake Awake™ technology which senses motion to power the sight on and off.  In addition, Holosun manufactured this little sucker with a brain that “recalls” your last setting and makes sure you don’t lose those customized settings once the sight system turns off.

Worried about battery life?  The Holosun HE509T Red Dot Sight offers up to 50,000 hours of battery life.  That’s fifty as in fifty thousand hours.  Simply put, we don’t think you’re going to have to worry about buying a new battery for this sight system for quite a while.  All versions of the Holosun Red Dot Sight system are projected from the same LED, so you don’t have to worry about having to re-zero when changing reticles.

Altogether, the Holosun Red Dot Sight is a much better sight system for your firearm than traditional iron three dot systems.  If you want to start hammering that 5X target to shreds and not only hitting what you aim at, but sending that shot exactly where you wanted it to go, The Holosun HE509T Red Dot Sight this is the sight system for you.

Holosun Review


<br>Easy mounting
<br>All features work
<br>Clear sight picture with a little magnification
<br>Mounted on Glock 17 and 19. Had an issue with the elevation adjustment set close to max all the way down in order to zero. Possibly due to the optics mounting profile. Felt resistance in elevation adjustment, did not want to continue adjustment due to possibly damaging the adjustment.

Good but,


Just mounted the 509t to my g19 and had the same issue with elevation as the other review. Had to decrease elevation all the way down and it was close but still not perfectly zeroed. I used a CHPWS plate and tourqed everything to spec with fix it sticks. Shot fine and stayed on point after 100 rounds. Good enough. might contact holosun. I should of gone with an other 507c which is flawless.
