Holosun 407C vs 407K

[JohnnyTyler]

Finally taking the plunge into pistol optics and I think it's down to these two. I thought I had made up my mind on the C but the more I look at the K I'm starting to lean that way. My concern is the size of the dot, 2(C) vs 6(K). For those using the K or another 6moa dot do you find the dot too big or do 2moa users find the dot too small. Or am I too concerned with the size of the dot? I know a lot of it is personal preference but would like to know what the general consensus is. Please help the noob. Thanks.

Aside from the dot size, the optics are different sizes. The C is the standard RMR size base and has a larger window. The K has the smaller micro compact footprint and smaller optic window.

C = G19 sized pistols
K = P365 sized pistols

If your gun is already cut for an optic, you may not have an option.

Here's a side by side comparison between a 507K on a Staccato and 507C on a G19.
The reticles are both 2/32MOA



6 MOA dot = Speed
2 MOA dot = Precision

The combination of 32MOA / 2MOA "death doughnut" makes the 6 vs 2 discussion irrelevant in my opinion, especially if you are talking typical self defense distances. For that matter, if you index the edges of the sight on their chest / shoulders, your going to land COM hits anyhow.

It doesn't photograph well but it seems to me that it's easier to find the dot on the 507K.

Don't do co-witnessed sights either.

Thanks. Probably would've helped if I had bothered to notice that earlier. Like I said, NOOB.

I have and prefer the smaller dot C for pistol or rifle use.

Responding cause I'm in the process of transitioning from irons to an optic,
mainly out of necessity, and i just went through the same process you are now.

My first thought is that if you haven't already done so, try to get your hands on some pistols with those size dots.
Doesn't have to be the exact optic.
A 2moa is a 2moa right?
You're bound to know someone that has something.
Also I don't think you mentioned a specific use for the weapon. Maybe it doesn't matter. Maybe so.

My weapon is/will be used for daily carry and IDPA. It was recommended to me to get a 6 moa cause, as stated earlier, quicker. Also wanted it in green and the 407 was the only option I think.
I was lucky enough to get to shoot pistols with a 407 and 507.
Thoughts:
For me and most all the shooting i do with this pistol i think the 6 would be fine.
I seemed to pick it up quicker than the 2, and i could hit a 25 yd headshot in an IDPA target.
Not every shot, but thats typical for me no matter what handgun I'm using.
Typical with iron sights I should say, but this could change! I actually did put more rounds on target than usual.
The 2 moa needed brightening up considerably for me to pick it up compared to the 6.
But that same 25 yd headshot was a bit easier I'd say. So if'n you're wantin' to reach on out there and touch something the 2 would definitely help with that.
The wobble was intimidating at first.
And if you do shoot at some distance the 6 might obscure your target if it was small enough.

Mostly I think we might be okay with either one, but again i would recommend trying 'em out first just like you would a gun.

Funny thing is in the end it ended up being about the size and shape of the window.
Not dot size.

Hope you get something useful out of my ramble.

I wish I saved the money and went with the 407c over the 507 - the death doughnut is wasted on me with an astigmatism. It's basically just a jagged 32moa dot lol

It's fine with my glasses but rarely do I wear them unless I'm specifically going to shoot.

If you wanna look through some examples sometime give me a shout. I have 407c 507c 507k and a couple different RMR models. I'm in southern Alamance Co.

I have a 407c (2moa) dot on a pdp. If i want a bigger looking dot I turn up the intensity. I have not felt the dot was too small

I registered just to say thanks for the great photos (and to see them fullsize LOL).

I'll be getting a gun milled so I can go either way (C or K).

I’m planning on getting some of these for my 365/320 but am also new to red dots. Has anyone here used the primary arms acss Vulcan retical? Is it worth getting over the 32 moa?

I have several Holosuns, and I agree that the death donut is the way to go. I have one on my AK47, S&W 622 & Mossberg 590 Shockwave. For all three weapons the circle/dot reticle works great. In fact, I wouldn't even consider another brand of dot sight now that Holosun has spoiled me on that feature.

I hadn't thought about that. I used to have a really bad astigmatism, but Lasik fixed that for me. I can see where the doughnut would be really messy with an astigmatism.
