First Impression

The Vortex Venom is small and lightweight! The lens hood is very thin and it's a two piece design unlike sights like the fully forged Trijicon RMR.

The Good

The battery access door is located on the top for easy access, and sight removal isn't required for battery swap.

Right out of the box, it looks and feel very solid and tight tolerance.

The Venom is similar to the Leupold DeltaPoint Pro minus the lens hood protection.

The Bad

It's solid quality for range use, but NOT for hard duty use.

Core Features

Window Size

I know what you're already thinking!

  • How big is the sight window?
  • Can I find my dot easily?
  • Is this sight going to making sight acquisition even harder than regular size pistol red dots?

The window size is similar to a Leupold DeltaPoint with enlarged width dimension : 0.58" X 0.77"

Very noticeable bluish lens tint. Not a big deal if using it outdoor with enough light

vortex venom lens hood

Here is the deal: The optic lens hood is super slim, and when aiming with both eyes open while focused on the target plane, all you see is a bright dot without really noticing the lens frame around the dot.

Above is the best we can replicate with a camera what your eyes will see, but seeing it with your eyes make a big difference.

Shooters with good pistol draw presentations can pick up the dot fairly easily and shoot from one stage to another fast.

Venom's most noticeable feature is the reduced lens frame view obstruction.


The Vortex Venom offers 3 MOA dot or the 6 MOA dot.

The large 6 MOA dot is recommended for pistol use for competition, range use, plinking and even for defensive use.

The bigger the dot, the fast you can pick it up and much less starburst for shooters with astigmatism

When I mounted this on the FN 509 LS Edge, I was blown away how fast I can pick up the dot consistently while using the low profile grip panel, so it angles my muzzle down to help me align the sight picture much better without readjusting my aim.

The pistol's grip angle matters a lot than most people realize.

Try a different size grip panel tonight and see the difference yourself!

It perfectly aligns the dot when you bring it up in front of your eyes, and consistent draw presentation even you're cross eye dominant help a lot.

If you still can't find the dot, please check out couple tips we've listed to help you find the dot on pistol easier.

Battery Life

vortex venom battery access

The battery compartment can be accessed from the top just like the Trijicon SRO

Most quality optics with a lot of thoughts put behind the design will feature things like this to optimize performance and user experience, and the Vortex Venom definitely has that.

In fact, Venom came out with this design way before Trijicon did. (Use provided allen key to open).

It takes a CR2032 battery to power the sight, and it lasts about 50,000 hours.

It's plenty of battery juice to last you almost 4 years before consider changing it, but we highly recommend you to replace the battery every year just to top it off.

The body of the Vortex Venom is a much more streamlined version of the Leupold DeltaPoint Pro minus the lens hood protection.

The body is made of 6061 T6 aerospace aluminum, and it's durable for normal use and can be used on shotguns.

As far as holding zero goes, the sight holds zero and has tight tolerance when mounting on guns.

Overall it's a good quality construction. 

On the bottom, there are mounting lug cutouts to secure the optic offered by various optic plates

1 MOA / Click is all you get with this optic for 3 MOA and 6 MOA models. 

It provides plenty of adjustment click range (130 MOA for elevation and 100 MOA for windage) for what it is designed for - CQB

The elevation and windage adjustment knobs are recessed to prevent accidental adjustment.

The turret directions reference the point of aim down range instead of reticle point of aim. If you want to know which way to dial the turret, we have a full guide on our website you can check out.

The only down side is that the click adjustment doesn't give noticeable feedback, so you really have to pay attention when you dial them.

Mounting Footprint

The footprint of the Vortex Venom shares compatibility with Docter/Noblex standard optics

Most optic ready pistols come with mounting plates for the Vortex Venom, and there are aftermarket mounts available to go on carbines, shotguns and PCCs.

Final Verdict

The Vortex Venom is a great entry level optic for the price. 

The window size is so slimmer that the lens hood almost felt invisible / blurred out when both eyes are focused on the target plane.

With the right grip and good handgun draw presentation, the reticle is fast to acquire to rock on the range

At this price point, the Vortex Venom (~$289) is the best alternative to the Leupold DeltaPoint, which will run you at least ~$600.
