Introduction

My recent descent into the joy of hand-gunning has given me many opportunities to try new things. One of them is checking out many new red dot options, and it has been a great journey. Today’s topic is a result of my search for a good red dot to put on my Staccato XC pistol. One of the many options I tried during that process is the very popular Holosun 507 Comp red dot.

The 507 Comp is a big windowed beauty, it seems to share some feature with other 507 models but its obviously larger. These types of red dots are optimized for competitive style shooting which I find to be very fun. Lets get into this neat little optic.

As I cracked open the box from Holosun, I was greeted by the typical accessories. I was happy to see that the Comp had come with a few different screw sets for different mounting situations. Though my Staccato had come with a specific 507 Comp screw set. The included tool was very handy for installing and adjusting the optic.

The 507 Comp also uses Holosun’s shake awake technology, which you can set to turn the unit on with movement. It will also power down after a set time of inactivity. Adjusting this feature and the brightness levels can all be done using the two + and – buttons on the left side. On the opposing side you’ll find the typical Holosun screw affixed battery door. I also notice that compared to other XL sized red dots the 507 Comp footprint was more universal than some others.

Using the appropriate optics mounting plate and screws, the 507 Comp dropped perfectly onto the XC’s slide. The back end of the red dot’s housing is thin enough that I can still see both front and rear sights through the window of the 507, which was also a nice addition. I adjusted the reticle to match the sights before heading to the range.

Rangetime

Initially my adjustments were pretty close, but I decided to refine it slightly to make sure I was hitting my point of aim. I spent a while going through the various reticle options to see what I liked. It’s really quite interesting how the different options present themselves. I like the dot with the largest ring, it seems to help in target bracketing and still gives the precise shot placement of the fine dot. That said I could see somebody using the circles instead for fast shooting up close.

Another reason I couldn’t have anticipated liking the large circle dot reticle was it’s utility at distance. Shooting the Staccato XC at distances like 100 yards is doable, and the bottom edge of the circle made a perfect holdover point for such distances.

I did notice, as did others who picked it up, that the reticle of the 507 Comp seemed a bit fuzzy. But after some comparison I think it was simply because we were looking at things up close. For example, looking across my desk at the wall the reticle seemed fuzzy. But when looking at a wall 20-feet away it was perfectly clear. And the same was true outside on the range, so I think perhaps there might be a slight parallax issue.

The various brightness setting were very visible even in the high heat of full noon sun out in this desert. I like being able to adjust the intensity of the reticle, and keep it low at night when its dark.

Pros and Cons

With such a large window, red dots like the 507 comp give you a huge field of view. This makes it very quick to find the target in the window. Additionally the larger reticle of the Comp gives you more to see, something to pick up on visually if you don’t immediately see the dot when presenting the pistol. This can of course be changed to fit your needs as your skill level varies.

The ability to change the reticle to fit your preference is a huge advantage in itself. Something I expect we’ll see quite a few other optics manufacturers adopting soon. The fact that this unit can be ordered in either red or green is also a nice option for those shopping.

According to the manual, the 507 Comp only has 30 MOA of travel for both windage and elevation. I didn’t find this to be a problem, and I had no issues zeroing the optic.

There are those out there who think it’s a shame to put a Chinese made red dot on such a fine pistol as the 2011. I will admit that I also second guessed the proposition, but followed through my plan based on a few good points made by fellow shooters. I was initially thinking of putting something like a Trijicon SRO or RMR HD red dot on the gun, despite having a significantly higher price and wait time. But many friends and associates pointed out that many of the popular domestic manufacturers don’t seem to innovate their dots like Holosun does. I was also told that its not if I’ll break an SRO but when. I guess I’ll continue to shoot with this one, while looking for additional good options to outfit my guns.

As far as problems with the 507 Comp, I could only say a few things. The aforementioned fuzzy reticle turned out to be a very small issue, and one I don’t even notice or care about now. I also had the battery cover screw come out and get lost. But to their credit Holosun CS was quick to respond and sent me a replacement as fast as I could have hoped.

Last Words

Having spent some time with this optic, and shot a great many rounds with it I am quite happy with my purchase. I wouldn’t say that its the greatest option out there, but it certainly fits my modest purposes very well. Due to the popularity of this red dot, I’d say that I am not the only one who thinks its a good option.

In the world of big window red dot’s, there are lots of great options. The 507 Comp offers nearly everything the competition models do and more. It provides adaptability in a robust and proven design. And it cost’s less than half of what some comparable units. That doesn’t mean I wont be trying those models out though, so stay tuned for more.
