1. Trijicon RMR Type 2 – Best Overall red dot

The Trijicon RMR Type 2 is a top-tier red dot sight, renowned for its sturdy build and precision. With a 3.25 MOA red dot reticle, it’s perfect for those with astigmatism and offers superb visibility in varied lighting. 

This sight comes with a unique battery mode that auto-adjusts the dot’s brightness after 16 hours. Plus, its grip tightly fits with your HK VP9’s slide. Waterproof and fog-proof, this sight is built to last.

Why to Buy: If you’re in search of a reliable, durable red dot sight for your HK VP9, look no further. The Trijicon RMR Type 2 is virtually indestructible and capable of enduring bumps, drops, and harsh temperatures. 

This makes it not just a choice but a choice for intense situations like military operations or hunting in extreme conditions. It co-witnesses seamlessly with iron sights, which means you’re not losing your backup aiming system. 

So, from precision to durability, it ticks all the right boxes.

Why Not to Buy: However, it’s not all sunshine and rainbows. One notable drawback is the battery compartment. You can’t just swap the battery without removing the sight. This can be a deal-breaker for some, especially if you’re in a situation where you can’t afford to spend extra time on adjustments. 

And let’s be honest, the RMR Type 2 isn’t exactly budget-friendly. If you’re not planning on using your HK VP9 in extreme conditions, there might be more affordable options worth considering.

Who Should Buy: So, who’s this sight really for? If you don’t compromise on quality and demand top-notch performance, then the Trijicon RMR Type 2 is your go-to. 

Military personnel, law enforcement officers, or dedicated hunters will find it meets—and often exceeds—all their needs.

The sight held zero like a champ, even after several rounds. Its tight grip on the slide ensured no wobble, enhancing my shooting experience. Trust me, this sight and the HK VP9 are a match made in heaven.

Meet the HOLOSUN HS507C X2, a worthy alternative to the coveted Trijicon RMR. With its large display and clear dot reticle, you’re set for targeting, even in low-light conditions. 

It features a solar failsafe, ensuring your dot stays visible, battery or no battery. Installation is a snap; it shares the RMR’s footprint, so no special mount is needed.

All these features come at roughly half the RMR’s price. That’s some serious value for your buck.

Why Not to Buy: Alright, let’s get real. While the HOLOSUN HS507C X2 offers a lot, it’s not the most rugged sight out there. If you’re someone who’s going to put your sight through the wringer, this might not be your best bet. 

Who Should Buy: So, who should go for this sight? Budget-conscious shooters, this is for you. If you want

3. Trijicon SRO – Wide Field Of View

Trijicon SRO is packed with top-tier features, from water and shock resistance to a large, unobstructed field of view. 

What catches my eye is its parallax-free nature and limitless eye relief. Three different dot sizes offer flexibility in use, from close-up shooting to bullseye competitions. 

The top-loading battery is a time-saver, and a tool-free design for windage and elevation adjustments streamlines the user experience. 

Why to Buy: This optic is your best bet if you’re seeking robustness, clarity, and versatility. Trijicon’s reputation for durability is upheld here; it survived my shoulder drop tests and rainy conditions effortlessly. 

The substantial field of view means you’re not just seeing a red dot; you’re seeing everything around it clearly. With multiple operational modes, it adapts to different shooting scenarios. The battery is long-lasting and easy to replace without having to re-zero. 

And let’s not forget it shares the same footprint as the RMR, making mounting incredibly easy.

Why Not to Buy: The major drawback is the price point; it’s not budget-friendly.  While it performs admirably, the cost might give pause, especially for casual shooters or beginners. Even though it survived my drop tests, if you’re an extreme adventurer, you may be looking for something even more rugged. 

Who Should Buy: This optic is an excellent choice for serious shooters, competitors, and hunters who require reliability and adaptability. If you’ve got the budget for it, and you’re after an optic that offers a diverse range of features without compromising on quality, this is the optic for you. 

Law enforcement agencies, or anyone requiring high durability and reliability in their equipment, will also find this a worthy investment. 

It can adapt to various lighting conditions and withstand weather extremes, which is great for outdoor enthusiasts.

My Testing 

I put the Trijicon SRO through the paces on my HK VP9, and it didn’t disappoint. The waterproof feature proved itself in drizzly conditions. 

It also survived multiple shoulder-height drops without a scratch. In terms of accuracy, the 2.5 MOA dot provided precise shots at various distances. 

Battery replacement was a snap, and readjusting the settings was straightforward. Overall, it held up exceptionally well.

4. SIG Romeo Zero – User Friendly

Sig Sauer Romeo Zero is your go-to when budget is a concern. This compact red dot sight perfectly fits the HK VP9. With a 3 MOA red dot, it’s spot-on for close-range, rapid-fire situations. 

A single-button operation makes it user-friendly. The unit is resilient, too, made from tough aluminum and certified as waterproof and fog-proof. 

Why to Buy: Let’s get real. Price matters and Romeo Zero makes quality accessible. First off, its small size and lightweight nature make it ideal for handguns like HK VP9. It’s simple to use, folks. 

A single button does the trick. But don’t let its simplicity fool you; it’s rugged enough to withstand heavy recoil. The red dot is bright and clear, making fast target acquisition a walk in the park. And let’s not forget about its durability. 

Made of robust aluminum, it’s built to endure and is both waterproof and fog-proof. Really, what’s not to love?

Why Not to Buy: Before you jump the gun, there are a couple of things to consider. The screws are tiny, and that can make installation a bit fussy. The 3 MOA dot might not cut it if you’re after long-range precision. 

And sure, it’s budget-friendly, but durability over time could be a question mark, especially when compared to pricier, well-established options.

Who Should Buy: So, who’s the right fit for this gadget? Novices, this one’s a gift for you. It’s straightforward to use, making it excellent for those still familiarizing themselves with red dot sights. 

Budget-conscious buyers, look no further. This offers plenty of bang for your buck. It’s also perfect for close-quarters situations, whether it’s home defense or target practice. 

If you have an HK VP9, the Romeo Zero is practically made for you, fitting seamlessly and performing remarkably well. 

My Testing 

Here’s the deal. I mounted the Romeo Zero on my HK VP9 and hit the range. Installation was a snap, although the small screws were a tad annoying. It held zero like a champ, even after 200 rounds. 

The sight acquisition was snappy, and the red dot was clear and bright even with quick movements.

5. Vortex Optics Venom – Best Value for Money

Sporting a 3 MOA red dot reticle, it’s perfect for rapid target acquisition. Even better? The sight is lightweight and compact, making it a no-brainer for your VP9. 

The Venom’s killer feature is its auto-brightness, adjusting itself based on your surroundings. 

Why to Buy: What can I say? Vortex Optics Venom is a catch. Let’s talk value; this sight gives you some serious bang for your buck. Perfect for beginners, the sight’s user-friendly features make it an excellent gateway to red dot optics. 

The auto-brightness is a game-changer, adjusting the dot’s visibility according to your surroundings. You’ll spot your target even in fluctuating light conditions without breaking a sweat. 

And get this: you can swap out the battery without taking off the whole unit or re-zeroing. It’s a keeper, folks.

Why Not to Buy: Now, hold your horses. As much as the Vortex Venom offers, it’s not perfect. One hiccup: it doesn’t support night vision. This could be a deal-breaker if you’re a night owl or want to be tactical in low light. 

Plus, while the 3 MOA dot is excellent for close-range, it’s not your best bet for long-range accuracy. 

Who Should Buy: This one is great for the greenhorns out there. The Venom’s your jam if you’re just dipping your toes into the world of red dot sights. The ease of use, from battery swapping to re-zeroing, makes it hassle-free. 

And hey, budget-conscious folks, this sight’s affordability without sacrificing quality should put a smile on your face. 

You’ve found your match if you’re looking for something to go on your VP9 for close-range shooting or fast target acquisition. 

My Testing

Alright, here’s the skinny. I mounted the Venom on my HK VP9, and off I went. Battery swap? Didn’t even have to dismount it. The auto-brightness? Absolutely nifty; that dot was visible in all sorts of light. 

On the range, fast target acquisition was, well, fast. Shot a couple hundred rounds, and it held its own. For its price, the performance exceeded my expectations. It’s not often you find a budget-friendly sight that punches above its weight.


  • Easy installation
  • Lightweight
  • Auto-brightness feature
  • Great value for money


  • No night vision support
  • Not ideal for long-range shooting
