Best Holosun HE509T-RD Enclosed Reflex Red Dot Pistol Sight
Closed Emitter Pistol Red Dot
Crafted specifically for pistols, the HE509T Closed Emitter Red Dot features an enclosed design that shields the emitter within sealed tubes, ensuring protection against water, mud, and dust. Its body, constructed from Holosun®'s Grade 5 titanium, exhibits over double the tensile strength and up to 5x the fatigue strength of aluminum.
Beyond its rugged exterior, the HE509T houses cutting-edge technologies. Solar Failsafe takes advantage of ambient light to power the sight during battery outages. The innovative Shake Awake technology activates the sight with minimal movement and conserves power during inactivity. Upon activation, the 590T offers a choice between a precise 2 MOA Red Dot or a versatile 32 MOA Circle Dot. Summing it up, the HE509T stands out as one of the premier dedicated pistol micro Reflex Sights in our selection.

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. ;-)
