Pistol Red Dot Pros and Cons

Pros

With a red dot, you can focus on your target while aiming. All you need is to see the target and the dot through the dot's window, and the dot will tell you where you'll hit.

Also, looking through a red dot compared to iron sights is like looking at a big screen TV instead of a phone: it's much easier to see your target and where your sights are on it.

  • Precise shooting. Long-range shots and precise shots are much easier.
    Police sometimes need that:
  • Overcoming poor eyesight. Cross-eye dominant? Older shooter? No problem.
  • Low-light shooting. A red dot is better than the best night sights in the dark.
  • Threat focus in self-defense. In a life-or-death struggle, our instincts force us to focus on the threat. Red dots work with these instincts instead of against them.
  • Situational awareness. Since you can focus on your target(s) instead of the front sight, you can quickly adapt to changes in the environment. This isn't a big deal on the range. But in a fight for your life? It's gold.
  • Shooting on the move. More situational awareness means you can move and engage targets faster and easier while moving. Again, not a thing you notice on the range, but you will when the targets shoot back.
  • Shooting moving targets. In a real gunfight, people move. As long as you can keep the dot in the window, it's easy to hit moving targets with a red dot.

Cons
  • Cost ($350+). A tough dot costs at least $250. A mount costs at least $100.
  • Needs suppressor-height iron sights ($100+) if you want irons as a backup.
  • Learning curve (3+ hours). It's mostly learning how to see the dot fast.
  • Not for pocket pistols. If you mount a red dot on a pocket pistol, it'll be too tall to fit in most pockets, and present a snagging hazard.
  • Maintenance. Battery replacements and cleaning cost more time and money.
  • Weapon light compatibility. When shooting in low-light with a weapon-mounted light (WML), the dot can wash out unless it's turned to max brightness. Some dots have an automatic mode, but it sometimes doesn't work right.
  • Can't be a ninja. When in the dark, a red dot on max brightness lights you up, too.

What Makes a Good Pistol Red Dot?

  • Tough. It must stay accurate and work after falling at least 5 ft. on concrete.
  • Long battery life (2+ years) reduces maintenance costs.
  • Top or side-loading battery so you don't have to dismount the red dot to change the battery.
  • Big window size makes a dot easier to learn and use.
    Wider makes faster target transitions (switching from one target to another, or tracking a moving target).
    Taller makes faster follow up shots, as you're less likely to lose sight of the dot on recoil. Reducing recoil can also help.
  • Large ring around the dot makes a dot easier to learn and use.
  • Lightweight, (2 oz. or less) so it doesn't affect your slide weight and recoil.

What MOA for Pistol Red Dot?

For a pistol red dot, 3 or 6 MOA are the most common dot sizes.

3 MOA

  • More precise for long-range shots.
  • More info on what you're aiming at, since the dot covers less of the window.
  • Better for dots with a larger dot mode, like Holosun red dots.
  • Harder to find the dot if you're new to red dots, or if it doesn't have a larger dot mode.

6 MOA

  • Easier for beginners to find the dot, if the red dot has no other dot modes.
  • Better for close-range shots.
  • Tougher long-range shots.

Overall, the best of both worlds is a 2-3 MOA dot with another mode for close-range shots (Holosun has a 32 MOA ring mode):

The ring on the Holosun can be turned off, so you can use it until you can find the 2 MOA dot quickly.


How to Use a Pistol Red Dot Sight

Finding the Dot Faster

It's going to take a lot of practice. Some things to keep in mind:
  • You can do most of this practice with a dry (unloaded) pistol.
  • To first find the dot, bring your pistol close to your face. Line up the pistol's back plate (or hammer) with the tip of your nose. You should be able to see the dot. Press out the pistol slowly, keeping the dot in the window.
  • Focus on your pistol presentation from ready. Get it on-target ASAP, so if you shot part-way through your presentation, you'd still hit the target.
  • When you present the pistol, keep your head still. Let the pistol's sight come up to your eye. With fewer moving parts, it's easier to get a consistent presentation.
  • To help you find the dot when you can't see it, try drawing a vertical line down the middle of the top of your red dot with a silver marker. Or, use a bright, narrow piece of tape to try it out. When you can see the line on top of your red dot, you'll know your sight is aimed too high.

Zeroing a Red Dot on Pistol

Point of aim is where your sights say you'll hit.
Point of impact is where you actually hit relative to where you aimed.
A target showing point of aim vs. point of impact.
Zeroing a sight means to set your point of aim equal to your point of impact at a specific distance. Since bullets travel in an arc, this affects your point of impact at all other distances.
Holdover is how you compensate with the sights so you hit where you intend.

If your eyesight is good, zero your dot for 25 yards. Otherwise, zero for 10 yards.

10 yard zero holdovers:
  • 5 yards: Aim 1 inch high.
  • 15 yards: 1/2 inch low.
  • 25 yards: 1 inch low.
  • 50 yards: 6 inches low.
25 yard zero holdovers:
  • 5 yards: Aim 1 inch high.
  • 10 yards: 3/4 inch high.
  • 15 yards: 1/2 inch high.
  • 50 yards: 1 inch low.
How do you zero your red dot? First, prepare for a range trip. You'll need:
  • At least 20 rounds of ammo (your defensive ammo, ideally)
  • Your pistol (with red dot installed)
  • A rest: a small sandbag, bag of rice, or bag of ammo.
  • Some Shoot N'C Targets (Check price @ Amazon )
    Birchwood Casey Shoot NC Targets for easily seeing where you hit
Next, the procedure:
  1. At the range, on the firing line, place a Shoot N'C target on your target.
  2. Place your target at the desired range.
  3. Adjust your red dot so it matches up with your front iron sight.
  4. Turn down your red dot's brightness as low as you can.
  5. Unload your pistol. Point it downrange and and do some dry fire trigger presses. Make sure the dot doesn't move when you press the trigger.
  6. Load your pistol. Take aim on the target, either with your usual firing grip, or resting the pistol's grip on your rest (sandbag, etc.).
  7. Fire on the target, ensuring the dot doesn't move during the trigger press.
  8. Repeat the previous step 2 more times, aiming at the exact same spot on the target each time.
  9. Note where the bullets hit the target.
  10. If there's a lot of variation, estimate the average point of impact.
  11. Put the pistol back on your rest, and line it up on the target like you did before.
  12. Without disturbing the pistol's alignment, dial the red dot's sight adjustment so that the dot covers where you actually hit the target (or the average point of impact, if there's a lot of variation).
    So if you aimed dead center of the target, fired, and hit 2" high and 4" right, move the dot so it would cover a spot on that target 2" high and 4" right of center.
  13. To verify, line up your aim on the rest and fire on the target again.
  14. If your last shot was way off, start over and have the best shooter at the range do the firing to make sure the dot doesn't move due to trigger press.

Are Pistol Red Dot Sights Worth It?

It depends. If you're using a pocket pistol, a laser sight is better.

If you haven't taken any training classes or competed at USPSA B class or above, a laser is probably better. Otherwise, it's a wash. For more info, see Red Dot vs. Laser: Head to Head.

For compact pistols and larger, it's complicated. Let's walk through some data to get a clearer picture.

USPSA Production vs. Carry Optics (2019)

Points and time on USPSA Carry Optics vs. Production classifiers (2019)
In competitive shooting, classifiers are short stages that test a few shooting skills at a time. Several classifiers are used together to rank a shooter (Grandmaster, Master, A class, B class, etc.) for competitions. Masters compete with Masters, and so on. Some examples:

In USPSA competitive pistol shooting, the Production division only allows pistols with minimal upgrades from the default. The new Carry Optics division is like its Production division, except:
  • Slide-mounted red dot sights are allowed.
  • There's no 10-round magazine limit.
How did Production shooters score vs. Carry Optics shooters? How much does a red dot sight help someone shooting a production pistol?

Key Takeaways
  • Assume the general public competes in USPSA D class (bottom 40%).
  • Both Production and Carry Optics divisions shot about the same speed.
    Ratio of time to complete a USPSA stage for Carry Optics vs. Production. There's no major difference across stages with few targets or lots of targets.

  • Carry optics shooters averaged 15% more accurate, making better hits.
    Ratio of time to complete a USPSA stage for Carry Optics vs. Production. There's an overall positive ratio for Carry Optics, and stages with fewer targets have more spikes in the ratio.

  • Most the gains from red dots were from B class shooters (top 60-79%) and up. In the chart below, the further a thin colored line is to the right of its thicker version, the more gains.
    Chart showing the gap between scores for Prodcution and Carry Optics shooters. The gaps only really show a positive for Carry Optics at B-class and higher ranks.
  • For B class or higher shooters, red dots offer 15-20% more accuracy.
  • Most of the red dot gains were from stages with shots over 10 yds., or head shots.

Red Dot in Force-on-Force (2017)

Miniaturized Red Dot Systems for Dut Handgun Use (2017)
This used force-on-force scenarios to test red dots vs. iron sights.

Key Takeaways
  • Those using a MRDS had significantly higher rates of using their sights.
    Graph of Red Dot vs. iron sight accuracy in force on force. Red dots had far fewer misses and more critical hits.

    Hit map for red dots in force on force scenarios.
    Hit map for iron sights in force on force scenarios.

  • The MRDS had significantly lower rates of misses, and significantly higher rates of critical (vital) hits.
  • With a pistol, one must hit the head or heart to stop a threat fast. Otherwise, the threat can keep attacking if it chooses to.
  • The accuracy gains found in competitive shooting may be magnified in defensive use.
  • The methodology of this study isn't ideal, but it's the only data available for red dots vs. irons in self defense.

Red Dot in Timed Drills (2017)

Red Dot Study – Key Points (2017)
Conducted by Karl Rehn of KR Training. Participants were tested on timed firing drills at 5 and 10 yards. They were allowed 10 or fewer dry fire presentations per sight type before testing began.

Key Takeaways
  • Participants performed better with iron sights than red dots.
    Lasers (especially green lasers) were comparable to irons.
    Graph of red dot vs iron sight hit rates for timed firing drills at 5 yards. Graph of red dot vs iron sight hit rates for timed firing drills at 10 yards.

  • At very close range and with minimal practice or training, red dots performed much worse than other sight types.
  • This study highlights the need to train and practice with a red dot. It is not an easy shortcut to better shooting.
  • It also reveals an easy learning curve for lasers.

Comparative Pistol Project (2011)

Comparative Pistol Project (2011)
This took 27 students, split them up into an iron sight group and a red dot group, and tested them on various courses of fire:
  • Stage 1: untimed fire at 15 yds, 1 target, 10 shots total.
  • Stage 2: timed strings of 2 shots at 5 yds, 1 target, 20 shots total.
  • Stage 3: timed strings of 2 shots at 10 yds, 1 target, 10 shots total.
  • Stage 4: timed strings of 2 shots at 10 yds, 2 targets 2 yds apart, 12 shots total.
Key Takeaways
  • Both groups had about the same number of hits.
  • They were also about the same speed on the timed stages.
  • However, the red dot shooters had significantly better hits than iron sight shooters. Their hits were in vital areas instead of non-vital areas.
  • With pistols, shot placement is critical to stopping threats quickly.

Pistol Red Dot vs. Iron Sights: Final Verdict

  • For trained and competitive shooters, red dots usually gave better accuracy at the same speed as iron sights.
  • Accuracy with a pistol is key to stopping threats quickly.
  • Accuracy gains mainly came from training and practice.
  • A red dot and some training are valuable investments for self-defense. If you can only afford one, get the training.
  • If you have eyesight issues and can't use iron sights, a laser sight is good if you don't have training.


Best Pistol Red Dot for Pros

If you carry a pistol for your job, reliability and durability is key. Closed-emitter red dots seal the window from rain, snow, dust, etc., and there are some awesome options on the market now. Which is best? The Sig Romeo2.

Why?

  • Best window size of any closed-emitter optic.
  • Built-in backup rear iron sights.
  • Hybrid design - if you need a lighter optic, you got it. If you need max durability, you got it, too!
The above features just aren't there for competing optics. Does the Romeo2 make any glaring tradeoffs in return? No. The Romeo2 is very well thought-out and solves common issues with red dots and with pistols that force you to choose between a red dot and a rear iron sight.

Before you buy a closed-emitter optic, compare it with the Romeo2. You may find the others wanting...

Best Pistol Red Dot for Carry Optics Competitions

If you're shooting USPSA, IDPA, or IPSC in a carry optics division, the Trijicon SRO has a huge honkin' window to help you win. It's not perfect, though:

  • Don't drop it on concrete
  • When flying with this optic in checked baggage, wrap it in the best bubble wrap you can find, because TSA tends to manhandle SROs to death
  • Glass quality isn't as good as new red dots from this past year
  • Some competitors report having to use Trijicon's excellent warranty, sometimes repeatedly, such that they bring two extra SROs to compete instead of just one spare.

Still, top competitors find that sweet, sweet window size is worth the headaches...

2 Best Pistol Red Dots for Everyone Else

If you don't meet any of these criteria:

  • Trained for over 40 hours with top pistol trainers and plenty of dry practice
  • Competed in USPSA B class or above
  • Competed in IDPA Sharpshooter class or above
  • Are a SWAT Officer, US Marshal, or part of Special Operations Forces (SOF)
Then the following red dots are for you.

Holosun 509T ACSS Vulcan

The Holosun 509T is the best closed emitter optic for everyone. Why? The 509T with the ACSS Vulcan has a special reticle that instantly shows you how you need to point the gun to see the dot, and for 99% of shooters today that is a godsend. No other closed-emitter optic makes it so easy to find the dot and learn to use it.


Even without this unique feature, the Holosun 509T holds its own against other closed-emitter optics for its great price, window size, durability, battery life, quality, and ergonomics.

Holosun 507c ACSS Vulcan

If you aren't in rain or extreme weather, the Holosun 507c ACSS Vulcan is the best choice. It has the same ACSS Vulcan reticle as the 509T-RD-ACSS, making it easy to acquire the dot and learn.


But it's an open-emitter optic: you give up some durability and save over $100 and some weight on the slide. Its durability is a close second only to the Trijicon RMR, and that's plenty for a concealed carrier or casual shooter. You can drop it on concrete a few times and it will keep working.

Vortex Venom - Best Budget Pistol Red Dot(?)

The Vortex Venom is the best you can get on a budget while still being reliable. Cheaper red dots tend to break, causing you to spend even more money. Be aware, though, that your pistol may not be compatible with the Venom...if it's not, it may cost an extra $50 to use this red dot. In that case, choose the Holosun 507c instead - you get much more for the money, especially if you get the ACSS Vulcan version.

Leupold DeltaPoint Pro

The Leupold DeltaPoint Pro once stood apart for its big window, easy battery changes, and attachable backup irons. At the time, that was an acceptable tradeoff for its lagging durability and reliability comapred to the Trijicon RMR.

But today, compare the Sig Romeo2 with the DeltaPoint. The Romeo2 is a reliable tank of an optic with a bigger window, and it even fits in most of the same mounts as the DeltaPoint! What does the DeltaPoint offer that the Romeo2 doesn't? I can't figure that out, but maybe you can.

If you can find a use case where the DeltaPoint Pro makes more sense than the competition, by all means check the best available price for it below.

  • Fits Leupold DeltaPoint Pro mounts (with no bumps)

Trijicon RMR

When it came out, the Trijicon RMR stood above all other red dots for its durability, reliablility, and outstanding warranty. But now there are competitors that match it, and they have a bigger window, better reticle, easier battery changes, better glass, better battery life, etc.

This is still a great pistol red dot, and if you're sure this is the right one for you, great. But please compare the RMR to the Holosun 509T with ACSS Vulcan and the Sig Romeo2 before you buy.

  • 3 target modes: ^, circle, or ^ + circle. The circle helps immensely with finding the dot on presentation.

Aimpoint Acro P-2

This is a great quality optic, solving glaring issues in the Acro P-1. But in context, there are better options for most people. The Holosun 509T with ACSS Vulcan is better for 99% of shooters. For the 1%, the Sig Romeo2 has a bigger window and has built-in backup iron sights.

But the Acro P-2 has the best battery life of any closed-emitter optic today. If that's most important to you, then the P-2 is for you.

Steiner MPS

The Steiner MPS is one of the 4 great closed-emitter optics that came out in the past year. But before you buy it, compare it to the Sig Romeo2. Is there something the MPS does for you that the Romeo2 doesn't? What about the other way around? The same can be said for the Holosun 509T with ACSS Vulcan reticle.

Also, the MPS fits the Aimpoint Acro footprint, but not all of them. Double-check compatibility with your pistol mount before you buy.
