Product Information

 Holosun HE509T-RD Enclosed Reflex Pistol Sight

Specifically designed for pistols, the HE509T features an enclosed design that protects the emitter within sealed tubes, so it can't be obscured by water, mud, and dust. The body is made from Holosun®'s Grade 5 titanium body, which provides more than double the tensile strength and as high as 5X the fatigue strength of aluminum.

It's an ultra-tough Red Dot Sight, but it's what's inside that counts. And inside the HE509T is a handful of Holosun's premier technologies. First and foremost is Solar Failsafe, which uses ambient light to power the Sight in the event of a battery outage. Next up is Shake Awake technology, which "wakes" the Sight at the slightest movement and shuts it down during periods of inactivity. Once "awake," the 590T provides your choice of 2 MOA Red Dot, 32 MOA Circle Dot. It all adds up to one of the finest dedicated pistol micro Reflex Sights we offer.

This thing is NASTY!

I do mean NASTY as in plain old excellent. My only variation is I have the ACSS version instead of the donut of death. I've dropped it, run it in the rain, and left it on for the Shake Awake feature - and though I've only had it for about a month - kicks on everytime. Now I do have this on my Glock G45 MOS (G19 slide w/G17 frame) which is my EDC and the battery has held up this far. Getting on target is as simple as it gets. Has held zero for almost 1k rounds without a hiccup. Now I'm not beating it up, but I'm not "babying" it either. Don't have to worry about pocket lint, rain, mud, debris blocking the emitter - though a simple hard blow usually takes care of that on some of my other exposed sights - this one is no worries. Definitely check it out if you're looking. Either this with the donut of death ret options or the ACSS ret both do the job without going the extra what, about $150ish for the Aimpoint ACRO. Of course I'll end up with it sooner or later, but I can't imagine it being any better than this Holosun, and that's for sure!

Sweet, tiny, enclosed reflex site, for any need!

I've got one of these on my carry pistol and as an offset sight on my Recce rifle. They're fantastic: light, rugged (titanium housing), long lasting (battery life extended with shake-awake and solar cells), and minty fresh (multi-reticle and auto-adjust brightness options). I will say, I love the ACSS version just slightly better on my pistol, but it's very good with the standard multi-reticle offering. Hey, WPS! Get the ACSS version on here, too. ;-)
