6.5 Creedmoor
In 2019 when I purchased my SIG P365XL, it could be paired with a Romeo Zero optic or Holosun 407k/507k. At the time the 407k/507k was only available in red, and after some time I was able to pick one up at launch. Shortly after Holosun gets slapped with a lawsuit from Trijicon regarding the button location on some of their optics. The two companies come to a settlement and Holosun re-designs the location of the buttons, leading to an "x2" model series.
Fast forward to late 2021, and there are now green dot options for the 407k/507k and 509t. Originally I was going to get a 509t-GR but they're even harder to find than the 507k versions.. Plus I carry my 365XL more than the M&P the 509t sits on.
I found a great deal on the 507k-x2 green ($265 shipped from Holosun Technologies 507K-GR X2 (Green) - Ibex Armament, OOS as of this post) and decided to compare.
In the following 5 pictures, the 507k-RD (red dot) is on the LEFT, and the 507k-x2-GR (green dot) is on the RIGHT:
Dirty lens from being carried, should have used canned air to clean it before taking pics - you can also see the emitters.
Here you can see how the buttons changed. They are smaller, and I did find a little harder to adjust at the range, but you wouldn't normally be adjusting too much. The "x1" version was definitely easier to adjust without looking, but lawsuits and all that..
I found it interesting that wires are visible in the original - I wonder if that would have affected the water resistance rating.
I was able to get the new model mounted and to the range this week - I really like the green over the red. I tried to get some "first person view" photos -
I had a hard time getting the iPad to focus on the green dot - it looks larger than the red dot but it really isn't; it WAS brighter (could have been battery life, the red dot was due to have a yearly battery change), and when I turned the brightness down on the green it was fainter than the red photo.
Now the big question people with astigmatism (like me) will have: Is the green dot better than red?
The answer will be different for everyone. I also have a Holosun HE510c in Green for a rifle. I have very slight astigmatism which makes most red dots a blurry mess, but the 510c is VERY clear and absolutely usable without corrective lenses. I was hoping this would translate to the smaller models.
With the 507k, at this time I can discern no particular difference between the red and green versions regarding clarity. They are still very usable to me - it also helps they are 2 MOA dots. At normal pistol ranges, I would have no issues using either in a defensive use. If I had to make a precision shot I would want my glasses to be sure though... Another trick I've seen mentioned is to have the dot at the lowest setting where you can still see it.
It was cloudy out and I shot the optic only indoors, so I can't say how it'll be in sunny weather. This was a mild concern with the red version unless you cranked the setting up high.
