Holosun 509T X2 Overview
The Holosun 509T X2 is an enclosed emitter pistol optic made out of Grade 5 Titanium. It has a custom 509T clamping footprint, but ships with an RMR adapter plate. There are many aftermarket 509T adapter plates which can be found here.
The 509T X2 is one of the most durable enclosed emitter pistol optics on the market. It’s intended for use on compact or full size pistols. For the best reliability, we recommend mounting the 509T on a slide that has a direct RMR cut slide. If you have a pistol like a Glock MOS with the RMR adapter plate, you would need to create a “plate sandwich” to mount this optic which means stacking two plates on top of each other. In this case we would recommend eliminating one plate by purchasing something like the Glock MOS to 509T adapter plate. This will increase reliability.
The 509T X2 features the MRS Reticle (multi reticle system). This gives you a 32 MOA outer ring, and a 2 MOA center dot. The outer ring is useful for finding the dot and up close shots, and the 2 MOA dot is great for precise shooting.
In addition to it’s ultra durable Grade 5 Titanium housing, the 509T X2 has a solar failsafe, shake awake, auto and manual brightness modes, 2 nightvision modes, IP67 waterproof rating, side removable battery, and has a battery that will last between 20k-50k hours depending on reticle and brightness levels.
The MRS reticle can be toggled to use the 32 MOA circle or 2 MOA dot only by holding down the “-” button for 3 seconds.
If you are looking for a duty grade enclosed emitter pistol optic at a competitive price, then this is it.
Holosun 509T X2 Reticle
Freedom Gorilla Staff Review
The HE509T-RD X2 is an enclosed reflex optical sight designed for pistol applications. Its features include a Titanium housing, Holosun’s Super LED with up to 50k hours battery life, Multi-Reticle System, Solar Failsafe, and Shake Awake technology.
Let’s start out with what an enclosed emitter optic is and how it compares the open emitter optic. Unlike the 407 or 507 k and c series, which are open reflex optics, the 509T is an enclosed optic. Enclosed optics feature an enclosed emitter that utilizes a hood-like system and an additional lens to protect the emitter and ensure nothing can come between your lens and the emitter. A drop of rain or snow or lint on the emitter can cause your reticle to spatter and starburst. With no reticle, an optic is quite useless. With an enclosed optic, this is not an issue at all.
So when deciding if you want an open or enclosed emitter, in my opinion I’d think about how durable you want the optic to be and how much you want to spend. If you’re hard on your guns and want a bulletproof reliable red dot, it’s hard to beat these closed emitter red dots. Especially since the 509T has a titanium casing that can take a beating.
Now let's look at some of the features of this optic. Like other Holosun pistol optics the 509T has shake-awake technology, Solar FailSafe, 50k hours of battery life, and a multi reticle system.
As far as settings go, like other Holoson optics this also has the auto, manual, and lock mode. Auto Mode is the default setting and it operates with the solar cell and internal battery two-way power supply. Essentially based on your ambient lighting level, the sight will auto adjust the brightness of the dot and also switch between battery and solar cell power if the solar cell cannot drive the reticle alone.
You can switch to manual mode from auto mode by holding the “+” brightness button for about 3 seconds, you’ll know it’s on manual mode when the reticle blinks once. In manual mode there are 12 reticle brightness levels. Level 1 and 2 are night vision compatible and obviously setting 12 is the brightness. You can increase or decrease the brightness by pressing the “+” or “-” brightness buttons. Personally I always leave mine on manual mode and about setting 6 with the 32MOA ring only. And one cool feature is the sight will remember the last saved brightness setting when powered on and off.
Next, let's cover the installation on a slide. It is different from the K and C series, but it is still not complicated to install. The 509T comes included with a RMR adapter plate, which is the same footprint as the 407/507C, and Holosun also sells a MOS adapter for the 509T. To install the 509T, first you have to attach the mounting plate to the slide using the two included 6-32 T10 flat head screws and tighten the screws to 15 in/lbs. Then using the included T10 Torx tool, loosen the clamp screws and attach the 509T onto the plate so the recoil lug engages the slot on the plate. Then apply forward pressure and tighten to 20 in/lbs.
A side note here - while looking at the 509T I was wondering if the clamp would fit onto a picatinny rail, and it does not but I did see an adapter that would work for that.
As for its dimensions the optic is 1.6x1.6x1.13. It weighs 1.72 oz. and the window size is 0.66x0.9. So let’s compare that to the 507C, which has the same footprint. The 507C is 1.78x1.15x1.15. It weighs 1.5oz. And the window size is 0.63x0.91. Overall the dimensions are pretty similar but the 507C is slightly longer. I would have thought that the 509T would have been a bit more heavier since it is titanium instead of aluminum and has a second lens, so that’s cool to see.
Overall the closed emitter optics from Holosun are a great choice for someone who wants absolute reliability. Let us know in chat or through text if you have any additional questions!
