If you are in the market for a pistol red dot with a large window, holosan 507 comp and this Vortex Defender XL There are two top options to consider (at least without spending Trijicon). SRO Wealth). They are both reliable, have sizable windows, and generally have good red dots. So, which one should you buy? Here are the key differences and similarities.
Tolerance
Skip testing the Holocene 507 Comp and Vortex Defender XL
i have about 5,000 rounds Vortex Defender XL and ₹2,000 on the Holosan 507 comp. But it seems like I have to multiply those round counts by at least three to get close to seeing failure. If you want to hear the perspective of people with high-round counts on these optics, check out This video is from Joel Park And This video of Brantley Mary.
Although I can’t fire ammo like a professional shooter, gravity is free. So, I dropped both optics from waist height onto concrete with double Alpha dry-fire mags to simulate loaded weight. Both survived the drop test with only cosmetic scratches and zero shift.
parallax
Holosun vs Vortex: Parallax test at 25 yards
To test the parallax, I clamped the gun to a tripod and set up a USPSA target at 25 yards. With the dot in the center of the A zone, I moved my head around and checked for any changes in the aiming point. holosun It was practically parallax-free at the edges, except for the top and top-right corner. At those locations, the point shifted from the center of the A zone to the edge of the A zone. The Defender XL was parallax-free.
window size
DIMENSIONS
I measured the window size at both points with calipers and they are almost the same. The biggest difference is that the Vortex is slightly longer than it is wide. The Holocene is much wider than it is tall. To me, the vortex looks and acts like a big window because most of my dot movement and index issues are vertical.
point
The Defender XL is available in 2, 5, or 8 MOA red dot sights. You can also get a green 3 MOA dot. The HoloSun 507 Comp has a 2 MOA dot, and you can select an 8 MOA, 20 MOA, or 32 MOA circle. It comes in red, green or gold colors. If you don’t mind a 6 MOA dot, you can go with the Holuson 407 Comp, which will save you about $100 and is identical except for its reticle.
If you’re looking for advice on which dot size to choose, I would choose the 2 MOA option in any optic. The smaller dot allows you to aim more accurately, and you can run it at a brighter setting without the distraction of the starburst.
But my Vortex XL is the 8 MOA version, and it sits within a credit card on a USPSA target at 25 yards. So in most shooting, it’s not stopping me from being accurate. The main downside is that I have to monitor the brightness more closely. If it’s kept a little too bright, it becomes distracting.
point glow
Both red dots become bright enough to shoot in full sun. The Holocene’s Dot remains sharper at the maximum brightness setting and doesn’t glare as badly as the Vortex. The HoloSun has 12 brightness settings, and the Vortex has 10. Both red dots have button lock and shake-awake features.
battery life
Advertised Battery Life
- Defender XL: 25,000 hours
- 507 Comp: 50,000 hours
HoloSun doubles the advertised battery life of the Defender XL, so if you hate changing batteries, the 507 Comp is for you. But replacing the battery of Defender XL is quite easy. You simply press a pin and the battery door opens. The 507 Comp uses an annoying little flat head screw to secure its battery door. This is a minor quibble that you’ll only have to deal with once every five years if the battery lasts as advertised.
The Upshot
The performance of these red dots is so similar that which one is right for you depends largely on your personal preference, the deal you get, and the gun you have. Vortex Defender XL Delta Point Pro uses footprint and 507 comp Compatible with RMR footprint. That alone will probably be the deciding factor. A note for Glock MOS owners is that the Vortex comes with an excellent MOS mounting plate. This will save you about $100 because if you go with Holosan for your Glock you’ll want to purchase a plate from a company like Arise or Forward Control Design.
The Vortex costs around $400 and the HoloSun 507 Comp costs around $370. But, both regularly go on sale at lower prices. If you still don’t have a clear favorite, pick the best deal you can find.
