Top Product List: My Picks for the Best Red Dot for Beretta 390
Before diving into the detailed reviews, here’s a quick rundown of my top recommendations:
Now, let’s break down each of these options with detailed reviews.
Trijicon RMR Type 2
Description
The Trijicon RMR Type 2 is a rugged, compact red dot sight designed for hard-use environments. Built with a forged aluminum housing, it’s a favorite among military, law enforcement, and serious shooters. It offers a 3.25 MOA dot, ideal for balancing precision and speed, and features automatic brightness adjustment to adapt to changing light conditions.
Specifications
Best Features
The RMR’s standout features are its durability and automatic brightness control. The rugged construction shrugs off recoil and harsh weather, while the brightness adjustment ensures the dot is always visible without manual tweaking.
Pros and Cons
Personal Experience
Mounting the Trijicon RMR Type 2 on my Beretta 390 was a game-changer. I used a custom Picatinny rail adapter to secure it, and after zeroing it at 50 yards, I ran it through a grueling 200-round session of skeet and trap. The dot stayed crisp, and the sight held zero perfectly, even with the shotgun’s stout recoil. I took it hunting in drizzly weather, and the sealed design kept it fog-free and functional. The automatic brightness was a lifesaver—transitioning from shaded woods to open fields, I never had to fiddle with settings. My only gripe was swapping the battery, which required removing the optic and re-zeroing, but with a four-year lifespan, that’s a minor hassle.
Customer Comments
Online, shooters rave about the RMR’s reliability. On forums like ShotgunWorld, users call it “indestructible” and praise its clarity, though some balk at the cost and note the battery swap inconvenience.
Mounting
The Beretta 390 isn’t optics-ready out of the box, so you’ll need a Picatinny rail or custom mount (like a SpeedBead or saddle mount) to attach the RMR Type 2 securely.
Aimpoint Micro H-2
Description
The Aimpoint Micro H-2 is a compact, lightweight red dot built for rugged use. With a 2 MOA dot and a reputation for exceptional durability, it’s a top pick for shotgun enthusiasts. Its high-quality lenses offer superb light transmission, making it ideal for all-day shooting.
Specifications
Best Features
The Micro H-2 shines with its insane battery life and robust build. You can leave it on for years without worrying, and its compact size keeps your Beretta 390 balanced.
Pros and Cons
Personal Experience
I’ve had the Aimpoint Micro H-2 on my Beretta 390 for over a year now, and it’s been a dream. I mounted it using a low-profile Picatinny rail, and after a quick zero, I took it to the range for some sporting clays. The 2 MOA dot was perfect—small enough for precision but quick to find in fast-paced shooting. I’ve dropped it accidentally on gravel, blasted through 300 rounds in a day, and even left it out in the rain overnight—zero issues. The battery life is unreal; I haven’t touched it since installing it, and it’s still going strong. It’s not the lightest option, but the trade-off in durability is worth it.
Customer Comments
On Reddit’s r/Shotguns, users love the Micro H-2’s ruggedness. One commenter said, “It’s overkill for a shotgun, but I’ll never buy anything else.” Some note the cost, but most agree it’s a long-term investment.
Mounting
You’ll need a mount (Picatinny or custom) to attach the Micro H-2 to the Beretta 390, as it doesn’t bolt directly to the receiver.
Holosun HS510C
Description
The Holosun HS510C is a versatile, open-reflex red dot with a multi-reticle system (2 MOA dot, 32 MOA circle, or both). It features solar power backup and a titanium-alloy hood, blending affordability with premium features.
Specifications
Best Features
The multi-reticle system and solar failsafe are killer features. You can switch reticles for different scenarios, and the solar panel keeps it running even if the battery dies.
Pros and Cons
Personal Experience
I mounted the Holosun HS510C on my Beretta 390 using a saddle mount, and it instantly became my go-to for home defense drills. The circle-dot reticle was a revelation—fast for close-range targets, yet the 2 MOA dot let me nail slugs at 75 yards. I tested it in a downpour, and the solar backup kicked in seamlessly when the battery got wet (my fault for not sealing it properly). After 150 rounds, it held zero, and the shake-awake feature meant it was always ready when I grabbed the gun. It’s a bit chunky compared to the RMR, but for the price and features, I can’t complain.
Customer Comments
On X, shooters call the HS510C a “budget Trijicon” with praise for its reticle options. Some mention the weight, but most love the bang-for-buck ratio.
Mounting
A Picatinny or saddle mount is required to fit the HS510C on the Beretta 390.
Vortex Venom
Description
The Vortex Venom is a sleek, lightweight red dot with a 3 MOA dot, designed for quick target acquisition. Its top-load battery compartment and clear glass make it a practical choice for shotguns like the Beretta 390.
Specifications
Best Features
The Venom’s lightweight build and top-load battery (no unmounting needed) stand out. It’s easy to maintain and keeps your shotgun nimble.
Pros and Cons
Personal Experience
I slapped the Vortex Venom on my Beretta 390 with a Picatinny mount and took it dove hunting. At just over an ounce, it didn’t throw off the gun’s balance, which I appreciated during long walks. The 3 MOA dot was bright and easy to pick up, even in the golden-hour glare. Zeroing was a breeze, and it held steady through 100 rounds of fast shooting. Changing the battery mid-trip without tools was a huge plus. It’s not as tough as the RMR—I wouldn’t trust it in a mud bath—but for casual use, it’s fantastic.
Customer Comments
Online reviews on OpticsPlanet praise the Venom’s clarity and price. Some users wish for longer battery life, but most call it a steal.
Mounting
You’ll need a mount (Picatinny or similar) to attach the Venom to the Beretta 390.
Burris FastFire 3
Description
The Burris FastFire 3 is a compact, budget-friendly red dot with a 3 MOA dot, perfect for shooters on a tight budget. Its simple design and top-load battery make it a practical add-on for the Beretta 390.
Specifications
Best Features
The FastFire 3’s lightweight design and affordability are its strengths. It’s a no-frills optic that gets the job done.
Pros and Cons
Personal Experience
I picked up the Burris FastFire 3 as a budget experiment for my Beretta 390, mounting it with a SpeedBead adapter. For the price, I was impressed—it zeroed quickly, and the 3 MOA dot was bright enough for a sunny day of trap shooting. I ran 150 rounds through it, and it stayed put, though I noticed a slight flicker after heavy recoil (fixed with a battery tweak). It’s not fancy, but for casual range trips, it’s more than enough. I wouldn’t take it into a swamp, though—it feels less robust than pricier options.
Customer Comments
Amazon reviews call it “great for the money,” with some noting occasional battery issues but appreciating Burris’s warranty.
Mounting
The FastFire 3 requires a mount like the Burris SpeedBead for the Beretta 390.
Leupold DeltaPoint Pro
Description
The Leupold DeltaPoint Pro offers a wide field of view and a 2.5 MOA dot, built for speed and durability. Its Motion Sensor Technology (MST) activates the sight on movement, making it ideal for dynamic shooting.
Specifications
Best Features
The large window and MST are highlights, offering quick targeting and power efficiency.
Pros and Cons
Personal Experience
I mounted the DeltaPoint Pro on my Beretta 390 with a Picatinny rail and took it to a 3-gun match. The wide window was a revelation—I could track moving targets effortlessly, and the 2.5 MOA dot was spot-on for both clays and slugs. The MST woke the sight instantly when I shouldered the gun, which saved me in fast-paced stages. After 200 rounds, it held zero, though I noticed the battery drained faster on high brightness. It’s a premium optic that shines in action.
Customer Comments
Shooters on TheHighRoad.org love the view and speed but sometimes complain about battery life.
Mounting
A Picatinny or custom mount is needed for the Beretta 390.
Final Thoughts
Choosing the best red dot for Beretta 390 depends on your needs. If you want durability and top-tier performance, the Trijicon RMR Type 2 is my favorite.
For value, the Holosun HS510C can’t be beat. The Aimpoint Micro H-2 is a tank, the Vortex Venom keeps things light, the Burris FastFire 3 saves cash, and the Leupold DeltaPoint Pro excels in fast scenarios.
Each requires a mount, but with the right setup, any of these will transform your Beretta 390 into a precision machine. Happy shooting!
