6 MOA

 

6 MOA. You will find it easier to become proficient with it. Once you are proficient, you will be faster with it at that distance, and plenty accurate.

 

Well, 3 is finer and 6 is easier to see at speed.

With irons, it's pretty important to be able to adjust your vision to adapt to different targets. With a dot, it's more important to choose a sight that you can use over the whole range of targets you'll encounter.

With either system, most of the targets you'll engage will not require optimized sights. And for damn sure, max HF is more about software than hardware.

If you can swing it, I'd recommend trying guns with both sizes - at least dry.

I would love to try both, but I only know one person who shoots with a red dot (on a pistol).

BTW, what is: HF?

 

I choose a three on my 17MOS. If I want something bigger I can cheat it a bit by increasing the intensity. I was in the same dilemma and glad that I went with the smaller.

 

this has been the advice I’ve been given. And the advice I’m going with.

 

Are you going to also use suppressor height sights?

I have a couple of optics equipped pistols with the suppressor height sights. The dot doesn’t come into play for me until beyond 15 yards. One is a Glock 19 Gen 4 MOS with an Trijicon RMR and Trijicon Suppressor height sights (6 MOA). The other is a Glock 34 Gen 4 MOS with a Vortex Venom and Trijicon Suppressor Height Sights.

Smaller dot gives you more precision.

Larger dot gives you more speed from the initial draw.

Both will give you the ability to reach out further with more success. On a Steel 2/3 IDPA Target, I can reach out to 50 yards either hand. 75 yards with two hands.

Never used a 6, so I can only comment on 3. It seems plenty big to me, and I do not "search" for the dot. It is right there every time as long as your presentation is consistent.

 

For self defense distances the 6 is faster and easier. However, for long distance target practice the 6MOA can overshadow your target so the smaller 3MOA is preferable.

I have both, but found I prefer the 6

On a pistol, it’s rather unlikely you’re going to shoot far enough for the increased size of a 6 MOA dot to matter.

Even at 100 yards, you’re talking sub A-zone size on a IPSC target.

I have a 3 MOA on my Glock, a 7 MOA Amber for my FNP-45, and a 12 MOA triangle on my woods rifle.

I would trade both of the pistol RMR’s for 6MOA dots if it wasn’t cost prohibitive.

 

Small dot is more for offensive needs and for finer control over bullet placement but will be slower to bring in target in uspsa type shooting when compared to 6 and even 8mopa some pro shooters use . Jerry Miculek uses a vortex venom but with a custom 8moa dot on his pistol and his old 6moa rmr on his shotgun .

I use 6moa dot on defensive handgun , ex match pistol and 2moa on a revolver I hunt with .

 

I have a 3, wish I got a 6.

I've tried a number of "better" red dots (mines a Vortex) and I need the bigger dot for my eyes even to find the dot in full daylight, even at the brightest setting.

It's why I pulled the red dot from my carry setup. Well, amongst other reasons.

 

Thanks for the feedback.
I knew the basics of larger size for speed and smaller for precision.
I am thinking that I am likely looking for speed, so I'm leaning towards the 6.
My gun loses the rear sight when you mount the red dot, so I'm planning on the Romeo Pro, which has a rudimentary back-up sight built in.

 

1 MOA is about 1" at 100 yards. So 6".

At 25 yards, that is 1.5"

Look at your typical front sight pistol at 25 yards. Does it cover 1.5" of the target? I bet it is that much or more.

So for a handgun, I see no reason to get less than 6 MOA. Unless you are specializing in 50 yard target shooting

That perspective reinforces my intent to go with the 6. Thanks

 

I have Fastfire III with 8 MOA on my CP-33 range gun and it works pretty well for me.

 

Out of curiosity does anyone know what the MOA is of the glock front sight?

ETA: I found the formula for this. It depends how far from your eye the front sight is.

MOA (front sight) = 21,600/((D *2π)/sight width)

D= 635mm (front sight to eye) this is 25 inches
sight width = 4.2 mm per Glock

Both dimensions need to be in the same units
21,600 is the number of MOA in a circle (360 deg x 60 MOA per degree)

So 21,600/((635 x 2 xπ) /4.2) = 22.74 MOA

 

WOW!
Those were some serious calculations.

 

I’ve shot 3 and 6 MOA dots. Both of my carry pistols with optics have Holosun 507’s with the green circle dot reticle. I pick up the green faster than red, and the circle dot is faster for me than either size plain dot.

 

I echo 6 moa for self defense use. 3 Moa is a little dot if you need to pick it up in a hurry.

 

3 MOA VS 6 MOA. Besides the obvious dot differences, 6 MOA dot under the bright daylight works so much better for shooters with astigmatism with the brightness cranked up. The reason is that the dot is bigger and appears much rounder for the eyes to see.

However, it's a different story indoor if you have bad eyesight. For a 3 MOA dot or smaller dot, when you crank up the brightness, all you see is the emitter starburst just cover up the dot completely. For a 6 MOA dot, the emitter starburst won't completely cover up the dot, and less emitter refraction.

 

I have tried both. My old eyes prefer the 6moa. Now if I can just find a 6moa green dot that won't break the bank.....RMR or RMRcc. I do have a sig romeo zero in a 6moa on my 43x MOS. It is the bomb!! I just wish the dot intensity was adjustable....

 

Thanks for the follow-up. I went with the 6 and I'm happy with it. And I do have a slight astigmatism.

 

6 MOA, unless you can find a bigger one. 4 MOA is too small for a handgun and more suitable to a short-range carbine shooting out to a couple of hundred yards. I have a 4 MOA and a 3.5 MOA on handguns. I use the 4 MOA for precision shooting to 50 yards and even for that use it would be better if it was 6 MOA.

Also, the bigger the dot the steadier it will look while you are aiming.

 

I have a 3.25 MOA RMR and it’s small. The Holosun circle dot is a good combo. Big enough to see quick with old fart eyes, but has the small dot if you feel the need to try and shoot bullseye stuff. The ACSS triangle is also better than the small dot for my eyes.

If your choice is 3 or 6 I’d go with the 6
