My Thoughts on the Holosun 407k vs 507k | How are they different?

[@jasonmartinez2434]

Good Video - For a EDC weapon, a 6 MOA red dot is PERFECT. Nothing else is needed! We are not trying to hit a target at 100 yards with a pistol, so grab the 407K, install it and practice with it....The End

[@Chris-pd7lg]

Absolutely practiced 100 yard shots in Iraq on a regular basis. Now look what Eli Dickinson did in an extreme circumstance 8/10 cold at 40 yards.

[@Trustme-im-forklift-certified]

6 moa dot is just too much for me personally. I like the 2 moa. Doesn’t obstruct the view

[@TeddyBear-lb9ho]

I haven't ever used a smaller dot but I have noticed a slightly annoying (not unusable) flare with my 6 moa Holosun 407k. I have the green reticle. I've heard the smaller reticles are better at not flaring up so bad. Not to say the 6 moa dot is baaaad. But it does flare a bit.

[@JasonReilich]

thank you for making my Decision easier

[@HaroldGodwinson24]

I bought the 407K, however I underestimated how my astigmatism would impact on how I view the dot. I have tried lubricating eye drops and I still see starbursts. I wish there was a way to improve this area. Normally I have decent vision. I wear prescription glasses, but I can see well without glasses. I’ve been considering upgrading to a 507K in green.

[@KuyaPow626]

If you want to focus on defensive shooting, you want the bigger reticle for speed. Get the 507k for the circle dot combo defensive use, then switch to the 2 MOA dot for competition and super accurate shooting.

[@tx_reaper5973]

You do realize the 407k has a 6moa dot, and the 507k has a 32MOA Circle / 2moa Dot Combo

[@KuyaPow626]

@@tx_reaper5973 Yes thats why I said what I said? 32 MOA is bigger than 6 MOA, but 2 MOA gives you the option to be very precise if needed. 507k is vastly superior if you want defensive use. Idk if youre agreeing with me or not...

[@InGratitudeIam]

For a rifle, I like the "donut of death" reticle with small dot when shooting at longer distances. For a handgun, I just want a dot that's easy to pick up quickly under stress, as engagement distances are typically shorter. The 407K green dot allows me to get quick, accurate hits under less-than-ideal conditions. YMMV.

[@pogchamp1038]

First red dot for me - 507k - I wanted the circle first (for comfort) but over time as I trained, moved toward the dot. - Great little optic. Clear enough with minor refraction (almost unnoticeable) and a great introduction to dots - MUST TRAIN WITH THE DOT! - Dont expect yourself to acquire the dot every time you present until you've trained enough. - Long live the Republic!!!

A good reason to go with the 507k over the 407k is if you have an astigmatism. a 2moa will look better than a 6moa for us Astimies. Dots already look bigger to us due to the fuzzy bursts and flares we get when using dots. So the smaller the better.

Great video. I run an RMR w/6.5 dot, Holosun 507c X2 and prefer the dot. I thought initially I’d like the circle/circle dot but not when I shot. That’s why I went the 407k for my G43. I also run a 507c ACSS Green and hands down the ACSS is my favorite, the chevron rocks.

[@JonesFamilyRanch]

Getting older I have switched over to red dots on most of my guns versus iron sights. I recently paired the 507K green dot with a S&W M&P 9 3”, and the comment on amount of feedback is spot on. I wanted something that honed in on the target and I went with the 2MOA. While this does give me more feed back, the thing I felt was worth the extra few dollars were the option. I feel the outer ring plus dot does tend to overwhelm the target, but the option to switch between the dot and ring is where the value is. I’m still working out what I like best for a permanent setting, but I’m sticking with the 2MOA for now. Best to all.

[@windsnowandstatic9075]

Personally I prefer the 507K though I agree the 407K is a great option. It would be interesting to see if ACSS would carry over the Vulcan reticle to the K series dots for folks getting into carry dots.

I bought the 407k for my G-48 mos for two reasons: One it's about a $100 cheaper like you said and second I have an astigmatism and the bigger dot is less distracting, rounder, not as starburst. It just looks better most of the time. Although I do have a 507c and it looks pretty good not as round, dot like as the 407k but still plenty usable.

[@djchino]

I have a 507k on my P365X and 407k on my G43x MOS and for sure I prefer the 407k, and the reason is simple- it's a bigger dot so I can find it quicker and has less feedback therefore I shoot faster and more accurate. I think it is because the small dot move so much I take more time aligning the dot on the target. Just like her I never use the big circle or the dot with the circle so I wished I had purchased the 407k instead. just my 2 cents on the matter.

[@eyang7]

[@rcdubya]

Thanks, Tessa. I found your comments particularly helpful. I’m new to dots so I don’t have any practical experience. But, given your description, I would probably just opt for the single dot function and probably not use the other two on the 507K. So, the 407K might just be the best choice for me initially, especially given the price difference.

[@WilliamB.-ij6gl]

this was great, exactly what I needed. thank you

[@brucemasson]

I thought about the Dremeling of the post, and thought to myself, What's the worst that can happen? I would have to buy a new slide. That being said, I did Dremel down the 2 rear post flat to surface. The front 2 post I Dremeled down about half way beause there are 2 notches under the 507k2 to seat the front 2 post. After that I shaved down the Right screw about 4 or 5 threds as to not let it interfere with the Firing pin mechanism, You will want to make sure you shaved down enough threads before placeing Lock Tight. 10 minutes later:::: I now have a co-wittnessed 507K2 with Stock Glock sights and NO ugly plate. Holoson sits Low in the Saddle "ON THE SLIDE", (not a plate) like a optic should.. Very pleased with results and had no issues.

[@ShawnHinck]

Awesome video, hit most of the major points. One thing I’d also add is, larger dots are less sensitive to light condition changes so I find myself messing with the settings less even though I prefer the smaller dots. That’s why I went 407k on my 43x. Now that there’s also a 407k with a green dot, that would honestly be my go to for a carry gun because of that. Competition though, smaller 1moa dots all day long

[@mnman8511]

Not trying to disagree with you here at all because i think there's a lot of personal preference in what dot people prefer but i think most competitive shooters are using 6 moa dots.

[@ShawnHinck]

@@mnman8511 many are, many have also switched to smaller dots. Dot size is 100% preference. The only reason I don’t go smaller on carry guns has to do with not wanting to need to adjust to compensate for lighting changes like you can run in to with smaller dots. Competition I get a sight picture to confirm my dot brightness before hand, carry and work, I don’t.

Notably more so if I do not have corrective lenses for whatever reason. Good video. I was looking for just this comparison as I require an optic for a Shadow Systems CR920 I picked up this weekend. One note: the MOA size of the circle on the 507K would be helpful. No biggie. I'll look it up. Keep up the good work!

[@anonypersona3189]

For the money, I think the 407k-GR is one of the best you can buy. Don't need anything else on a subcompact. You should do a review on the comfort concealment belt vs the Enigma. I haven't seen any reviews on that belt yet and it looks like it would be more comfortable than the strap that the enigma comes stock with.

[@jafo1701]

I don't have a 507k but have an Aimpoint Acro P1 on my Wilson Combat, it has a 3.25 MOA dot. I have a 407k on my 365XL. Practically I find the 407k easier to shoot, I pick up the dot faster, it doesn't shake as much so I'm not trying to fight myself to hit that perfect shot, it just appears a lot more stable. If it was a precision rifle, sure I'll take the smaller dot, but for a concealed carry handgun for myself I prefer the bigger dot. As for accuracy, my groups at 25 yards are about .5 inches larger with 407k, but you could also attribute that to the Wilson Combat which is leaps above and beyond the sig in terms of accuracy. In reality I can get center mass hits at 100 yards with my 365XL and the 407k so practical effectiveness with a handgun it makes zero difference. I guess in the end it's personal preference.

Something I see not mentioned in any video I've watched is if your firearm platform requires an adapter plate which will mean the dot will be sitting slightly higher on the slide. The 407k has 30moa elevation adjustment available and the 507k has 50moa elevation adjustment available. Depending on your intended zero that extra 20moa could make a difference especially if you are using a CH Precision adapter plates. Lesson learned and hopefully saving someone else grief.

[@Osprey1994]

If you are on the fence about a dot I really suggest you go for it, having a dot on at least one gun for dry fire is a big help. Reason being is that a dot will tell you things that irons won't...it will tell you that the shots a going to trend in a direction and then let you chase that rabbit down. PS. A dot will also punish bad presentation, and drive you to improve in almost every aspect. Maybe that's just me though...kinda a dog with a bone when it comes to stuff like this. But seriously I would recommend picking up an optics ready pistol that interests you and grabbing an optic for it, and if it doesn't work out you can always sell it and pop a plate back on.

[@Daddy53751]

I’ve used dots on rifles for years just due to ease of acquisition. (Eyes still work well enough for rifle irons) Never have used a pistol with one, but nowadays the eyes aren’t working as well with pistol irons so putting some serious consideration to moving into a pistol dot. I’m kind of point shooting now as I can’t get ahold of that front sight. (Arms have grown too short) As a first timer, I’m really leaning into the 507 as from the outside it seems nicer to be able to get ahold of that big circle, and with experience be able to move into the dot, or not depending on how it works out.

[@hollyfoxThe]

I run the 507k on a Max9 and keep it on the circle dot on low intensity. Most encounters are going to be close range so I prefer the circle dot. Besides, my eyesight is not what it use to be so the circle helps acquire the target. The only thing that bothers me with it is having to press both those little buttons at the same time to turn it off. Other than that is has been great.

As a marksmanship instructor in a previous life (Navy), I heard you say something alarming. I heard you say more "feedback" is a good thing (3:40). You also referred to your sight picture being shaky as "feedback". Please understand that is just not correct. A steady hand and sight picture is what is desirable. There are many reasons to pick the 407 vs the 507, price is just a minor factor. bigger dots are easier to get on target at closer ranges (point of aim is best for quick or snap shooting up to around 10' +/-) then when your target gets smaller say around 10 yrds or 30', the big dot covers around 2" where the smaller dot covers around 11/16". So the farther away you plan to shoot the smaller dot you need to shoot more accurately. The other major consideration is if you have an astigmatism, the 407 is best as it is easier to see. Oh yeah, why not mention red vs green dot? Please understand I am just frustrated with false information being disseminated as fact. It is great to have real women in this sport and with the mindset that they can protect themselves, it's empowering to them I'm sure.

[@shuumai]

On a small defense pistol, I'd go with the 407K green dot. My wife has a 507C with Vulcan reticle on her G17. It's steady, maybe due to it's larger size, 10 MOA across the chevron. (I just wish it were green.) We also have a 403C with 2 MOA dot-only on a rifle, which is good for static shooting at distance. I'd prefer a circle-dot for faster, closer shooting.

Of the two I prefer the 407k. If I use a 507 series I use them circle only. Quicker than the dot and no real world loss of accuracy out to 25. Of the bigger holosuns I think the 407co is unbeatable

I used to live near Conroe, TX. I worked at the Starbucks on 336 in front of the home depot. So miss the kolaches from a couple doors down. Galloway precision has an optic mount plate that will work with my pistol.

BTO Range is fantastic especially the rifle range with tablets to see your hits at 50-100 yds
