There are so many red dot options available on the market and most of them are compatible with Ruger 57. Finding the best red dot for Ruger 57 may require a lot of your time and energy.

Well, you would need to spend that time and energy if you were to find that on your own. You are here now, let me help you with this, and let’s find a good Ruger 57 optic together. Without further ado, let’s jump straight into it.

How To Choose The Best Red Dot For Ruger 57?

Now that you know what are some of the best optics for Ruger 57, you still need to make the decision to purchase one from the list. You can make your decision based on a couple of things.

You can set up a budget. Whether it’s a fixed budget or an estimate of how much you want to spend, both help. If you have a budget on your mind, your options will narrow down and you can pick up one of them with ease. Pick up the one that has the features you are looking for.

1. Sig Sauer SOR32004 Romeo3 XL 1X35Mm Sight

The first optic that I want to recommend with the Ruger is from Sig Sauer. A brand that you all love and trust. The Romeo series of red dot optics is known to be reliable and well-performing with all sorts of weapons. Including handguns like the Ruger 57.

The Sig Sauer Romeo3 XL is made out of aircraft grade CNC aluminum housing. The housing has an anodized finish. The housing is also rated to be IPX-7 waterproof rating. You can submerge the optic but it’s not advised to do that for fun.

The reticle is available in 6 MOA and 3 MOA sizes. The window is a 35mm one. Gathers plenty of light and generates stunning vision.

The glowing red dot can glow up to 12 levels of total brightness. With the help of a CR2032 battery, the optic has 10 daylight and 2 night vision adjustments.

What’s the expected battery life?

The battery life is expected to be around 25k hours. But that’s based on low-brightness settings. You will get a lower life than that if you use it with higher brightness.

Will this fit on a stock Glock 19x?

No, it won’t. You will need a Glock plate to attach this to your pistol.

Will this scope mount on a Beretta 1301 Tactical Shotgun?

The optic is designed to fit on Picatinny rails as well. The optic will fit on your Tactical shotgun.

2. Trijicon RM06-C-700672 RMR Type 2 Adjustable LED Sight

The RMR Type 2 has been recommended by so many, hopefully, you are not bored of seeing this here again. The Type 2 is known for its durable materials and excellent clarity. Thanks to the shockproof housing, the optic is capable of being used with rifles even.

The lens of the optic is fully multi-coated. It’s extremely bright and vibrant. It also features a 3.25 MOA reticle. The reticle is illuminated and you can adjust the brightness of your reticle as well.

There are a total of 8 adjustable settings and an automatic adjustable sensor present on the optic.

You will need a CR2032 battery to operate and Trijicon includes one battery in the box. That battery alone will last you a long time.

Unless you are someone who can’t use the optic without the highest illumination, then you will find yourself changing the battery every now and then.

Is this optic compatible with Picatinny rails?

Yes, it is. It has an available mounting plate compatible with Picatinny, weaver rail, ACOG add-on, riflescope add-on, etc.

Is this a good optic for Ruger 57?

It’s one of the best Ruger 57 red dots you can purchase right now. The optical performance and durability, above everything the ease of access and installation make it a good choice for Ruger 57.

What improvement does Type 2 have?

The key change is it includes a motion activated sensor. When you holster the weapon, the sight stays off. It also has a better battery contact to prevent battery drainage and provide better life.

Are there fake Trijicons?

Yes, plenty of them. Trijicon is not a Chinese manufacturer. If your optic says it’s made in China or Hong Kong, return it. It’s not the right one.

3. Leupold DeltaPoint Pro Reflex Sight

DeltaPoint is a complete red dot system from Leupold. The reason I say it’s a complete system is because you can purchase this with the mounting system that you want to have. The mounting height that you want to have.

Thus making it unnecessary to purchase other accessories to mount this on a rifle.

The red dot features a 2.5 MOA red dot reticle which is also illuminated. You can control the Leupold DeltaPoint Pro sights brightness as well. Besides the brightness, you can also adjust the windage and elevation of the optic.

The optic features an aspheric lens. The lens is durable, bright, and extremely clear. With Leupold’s twilight red dot light management system, the optic is a blast to use in low-light conditions.

That’s the reason why many use this to hunt squirrels and other small scale animals.

Can I use this in cold weather?

Of course, you can. You can use it in hot, cold, or rainy weather even. The shock, water, and fogproof housing is robust and will stand its ground on any weather you throw at it.

Does Leupold offer a warranty on their red dot sights?

They do. They offer a lifetime guarantee with their red dot sights.

Where is this made?

Unlike most other reflex sights which mostly originate from China, this one is an in-house design of Leupold which was built from scratch in the USA.

4. HOLOSUN HE508T-RD X2 Circle Dot

There are so many Holosun optics available on the market, that it’s easy to get lost among them. The HE508T-RD X2 circle dot is a reflex sight with an illuminated red dot reticle. The circle around the 2 MOA dot is sized at 32 MOA.

Instead of aluminum, Holosun HE508T-RD X2 is made out of titanium. Titanium is an extremely durable and lightweight material which is also expensive at the same time as well.

The optic also features a solar failsafe and shake to wake sensor.

You will need one CR1632 battery with the optic. The battery can last up to 50k hours and when it runs out in the middle of something, solar failsafe is there to back you up.

6. Vortex Optics Venom Red Dot Sight

The Venom is very similar to the Viper. The Venom comes in a 3 MOA or 6 MOA red dot reticle. You can choose your poison while purchasing the optic.

The lens used on this optic is fully multi-coated. It’s bright, and vibrant, and has no fish-eye distortion, color alteration, or mirage related issues.

Yes, it will. It supports Picatinny/weaver style rail with ease. As the housing is shockproof, you can also use this on a shotgun.

Does the brightness button feel cramped together?

While it looks like they are connected at the same joint, they are not. They are separated. But it takes a bit of time to get used to the tactility and distinguish between the two.

What kind of warranty does Vortex Venom have?

Vortex Venom has the same unconditional, unlimited, lifetime warranty that Vortex is known for.

7. Burris FastFire 3 Red Dot Sight

Burris is another hunting equipment manufacturer. They have been making rifle scopes and red dot sights for a long time now. A lot of modern companies aren’t even half of Burris’s age.

The FastFire series of optics was and still is quite good.

The FastFire 3 is available in different configurations. One of them being the standard 3 MOA and the other two are 4 and 8 MOA respectively. The optic has an option to adjust the windage and elevation of the optic.

Allowing you to tune the optic according to your gun. Which in this case, is the Ruger 57. The Ruger 57 with a red dot performs the best. And without a doubt, the FastFire III is one of the best options in this price bracket.

Does it come with a mounting plate?

It does. It comes with a Picatinny mounting system.

Will I get any warranty on this?

You will. You will get a forever warranty from Burris. It doesn’t matter if you are the first owner or the third. Burris will take care of your optic as long as it’s actually from Burris and not a fake.

Yes, it will fit the weaver supplied mount on a 22/45. You don’t need a gunsmith for that either.


While Ruger 57 can operate with a lot of different red dots and night sights, all of them are not a good choice in terms of durability or synergy. If your optic keeps dying on you and you have no way to prevent that, then you have a problem.

That’s why, I wanted to make a list of red dots that are proven to be durable and support the Ruger 57 as well. And performs incredibly at the same time. Thus, the list was made.

Hopefully, you have found the optic you are looking for and I hope your thirst for finding the best red dot for Ruger 57 ends here. Thanks for reading and I will see you on the next one.
