I know that green dots save me from the dreaded starburst. It is amazing just how many people see the green dots in much sharper focus.

[@freedomgorilla1]

thats great to know .. many people dont realize they have mild astigmatism until they get a red dot - i know that happened to me!

[@VSDalSheron]

thats because our eyes are keyed into seeing green more strongly than the other colors due to that photoreceptor type being more numerous than the others.

[@calangel]

That really is subjective. Green is at the center of the spectrum so visualizing it is a more 'relaxed' experience. The red sensing cones are more numerous, though a bit less sensitive generally than other colors. Green blooms more for me than red or yellow. I've looked through multiple green holosuns, and I would have had a serious case of buyer's remorse had I bought one without looking through it. Red is sharp and stands out for me, especially in the 6MOA version.

[@gkott78]

As a person with a diagnosed astigmatism, I have had no issues with 507c in red using the 32 MOA circle with the center dot. I have it on my competition firearm, and I love it. I decided to try a green 507k for my carry, and oddly enough my eyes couldn't handle the green. Although I picked up the green faster, it really flared on me and I couldn't utilize it. This is not an issue with the optic, it is completely my eyes and my cornea. I wound up returning it for the 507k in red and that's perfect for me. I highly advise to test these in person and see what works for you. They are fantastic sights.

[@ZensivYT]

Same thing happened to me, green flares so bad for me unfortunately. I have to stick with red

[@beethao3134]

Same here. I tried the hs510c in red and green and while the green was slightly easier to pick up, it flared so bad for me that I had to stick with the red. Not the fault of the sight itself, just my eyes. Edit: I am a bit color blind too though so that might be why.

[@jimsjacob]

Don’t know if you’ll see this, but the comment about the “star burst” for astigmatism people. My dominate eye does have a slight astigmatism so I was thinking to going to the green dot based on one of your comments about how users have reported that they seem better if you got this eye prob. But I was gonna go with the 6MOA instead of the 2MOA. But here you point out that it could be an issue. Long story to the simple question…. With my astigmatism, would you recommend a 2 or a 6MOA for EPS-GR-6?

[@jer3996]

Ive.know for quite some time that most human eyes are predisposed to seeing green over red. I still chose red even with a slight astigmatism because I live in a sea of green and shoot outdoors mostly. In my house I would choose green though. Interesting subject and I'm always interested why someone chooses one over the other. I think the word "best" should be reserved for the person using it. We all know what's best for us, but here in incognito land kids sure spout off about things they have zero experience with. Now give me one for Chesty!

[@typhoonjenkins8330]

Truthfully, after buying a bunch of 507c's (which are great dots) I have regrets. Why? I bought my wife a 407K w/6MOA dot and it's every bit as awesome as the 507c just without the extra 65MOA ring. It's available for 100 bucks less too. The ACSS reticle was my end all be all for a while, but that 6 MOA dot on the 407K is so easy to pick up, it's a no brainer to save a hundo and still get a great, durable dot, IMO.

[@freedomgorilla1]

Hey this is a great comment .. and we like the 6 MOA dot a lot too ... HOWEVER I have to point out that the 507c is a larger optic than the 407k. The 407k is the micro dot .... the 507k is the same size but has the MRS 32/2 MOA dot. The 507c and 407c are for the larger pistols or compacts ... and it's worth noting that the 407c has a 2 MOA dot unlike it's 407k little brother.

[@Woodstock271]

I picked up the 407k for my Ruger Max-9 after watching lots of videos on red dots. Being my first optic, I wasn’t sure I’d like it. I wanted the 507k for the circle/dot reticle options but didn’t want to pay a hundred bucks more for something I might not like in the first place. Turns out, I love the red dot! After zeroing at 10 yards and over a thousand rounds, I don’t know how I shot without it. Still considering upgrading to a 507k, but reading this comment makes me think I’ll stick with the 6MOA dot. It really is easy to pick up and I’m not sure if my aging eyes would do as well with a 2MOA dot, or the circle dot. For now, the 407k has flawlessly done what it’s supposed to do and I’m very happy with it. Tons of videos on dots later, I know for sure I’m sticking with Holosun either way. Their options are becoming endless and at the prices, just blow the competition out of the water. I think the Trijicon people have fallen asleep or something. And their prices are ridiculous for something with less features than Holosun has. Also, removing the dot to change the battery is just silly. The battery tray in the side is genius. I really like the idea of an enclosed and sealed emitter but so far I haven’t actually needed that for just range shooting. Speaking of the range, that’s where I’m headed today. Another relaxing day of punching holes in paper targets.

[@freedomgorilla1]

@@Woodstock271 glad you like it and well written. We do like the 407k as well.

[@ZhuJo99]

It has 32 moa ring. And you can turn it off.

[@Woodstock271]

@@ZhuJo99 , Yes it does. The 507k has a 32 MOA ring that can be turned off, leaving a 2 MOA dot. Don’t get me wrong my friend, I really like the 507k for the ring, it’s super cool. One advantage is, if you see the edge of the ring in the window, you can quickly find the center dot. That’s the whole point of the ring and I have no argument with that. It makes sense. And nobody will argue that it doesn’t look great. My first choice would have been the 507k for that reason. Especially when I was younger, there’d be no other choice but a dot and circle but none of these things existed when I was younger. Shooting pistols with only iron sights for decades sort of makes you wary of “improvements” to what you’ve already mastered over the years. Red dots were out a long time before I pussed-out and actually got one just to try. It took a lot for me and most people my age to change my game this much at all. I didn’t want it complicated with all sorts of parameters. (I can barely work my cellphone), Just a bright red dot will be fine. I really like the circle/dot on the 507k but found it more distracting than helpful. Again, to each his own. A six MOA dot on the 407k easily acquired and quickly, works great for me and I’m used to it. I used to be used to only iron sights. No need to complicate it much further. The “shake-awake” feature is a misnomer. There’s no “shaking” involved in making the dot light up. That in itself, shocks a caveman like me. Set the dot for 10 minutes to sleep and set the pistol on the shelf. In exactly 10 minutes the dot goes off. Amazing. Let’s see what happens if I just touch the pistol very lightly? The damn dot comes right on. I love that! Shake awake my ass, I barely touched it! Of course this all means the dot will be on continually while carrying. As it should be. Battery life is expected to be 20 to 50 thousand hours. Who gives a shit? Have batteries, will travel. Just like I would a needed flashlight in the woods. But after a year now, I haven’t needed to change the red dot battery. Go figure. Technology is frightening to us cavemen. Edit: Happy Thanksgiving Day @Freedom Gorilla and everyone!

You may want to mention the mount foot print and mount difference between the two red dots. It is pointless to buy a red dot that does not fit. Holosun does not make a red dot that has the Doctor / Noblex / Vortex / Burris Fastfire footprint standard. This is one of the most popular mounts.

[@freedomgorilla1]

Good point, I just updated the video description with that note. When making the video, I just assumed people would know, but better not assume and be on the safe side.

[@johnn7726]

@@freedomgorilla1Reason why I checked the description. I’m completely new to the gun market/scene with absolutely little to zero knowledge just a week prior. I’m assuming foot print is just the gun term for mounting bracket for optics? And does Holosun include multiple mountings for different pistols or do I have to buy those separately?

[@user-wo2rc3bf4x]

I believe one must purchase an adapter plate to use a particular “red dot” on a given firearm. Problem is the footprint available. Some guns have a “cut,” or in other words, footprint, and depending upon the red dot choice, an adapter may be needed. However, some cuts are simply not big enough to accommodate some red dots. For Example, an RMR cut, or Zev cut, will only accommodate certain “red dots.” I put that in parentheses because a red dot by definition does not encompass all Devices. An RMR cut is smaller than the cut that comes on a Glock MOS Model. The RMR cut is smaller than the Glock MOS cut, and therefore the RMR cut isn’t big enough for a Vortex Venom to fit, so in that case one must choose a “red dot” like the holosun 507c x2 because it has a footprint of an RMR cut, like the trigicon. Not sure if that helped at all, but it’s what I discovered trying to find an adapter plate so I could use my vortex Venom on an RMR cut slide, which I found I can’t because the vortex Venom has a bigger footprint than an RMR cut can accept. So, in my case I have to (there’s others that share a similar footprint) buy a Holosun 507c to put on my new Zaffiri G20 slide. Now, I’m trying to decide between a green or red reticle. I’ve got a bad astigmatism, and a dot looks more like a blurry ampersand. I wish you the best.

[@gmcjetpilot]

@johnn7726 It is crazy confusing. Not being a wise guy but Google it. "Footprints/Mounting Standards on Red Dot Sights" It gets confusing. Some manufacturers of red dots only use one footprint. Some manufactures have their proprietary footprint. Some manufacturers will offer several of the popular standards. It's a little frustrating since they can be so close but not fit. It can keep one red dot from fitting all your pistols. So you have to buy another red dot to fit. There are several standards. It's a mess. It can be navigated, but you have to know what footprint you need. Cheers

[@bar_yama]

What do you think about putting the 507k on full-size guns? In order to keep the optic flush with the slide?

[@freedomgorilla1]

Definitely don't see any problem with that if it will fit the gun. You would have less weight .. you will have a smaller window, but nothing wrong with doing that. Like I said you just have to make sure it will fit - that the mounting footprint is the same. The 507k has an modified RMSc footprint and the 507c has an RMR footprint.

Those are two different products. One is for thin, compact slides(G43, etc.) and the other for wider slides(G19,etc.). Makes no sense to compare them. We sell lots of them at our shop.

Hey thanks for the view. We compared them because people have asked us the difference, so I thought we’d clarify and highlight a few features between the two

[@barrysuss4421]

WTF. Because people who do not own both would like to know the differences and similarities.

[@gmcjetpilot]

Holosun lost my business. NO GOOD..... You NEED to mention the footprint on these. Holosun does not make Doctor/Noblex/Vortex mount footprint. It really makes me PO. They make Trijicon RMR, Aimpoint, Odd ball Unique footprint mounts, but No DOCTOR? That frustrates me. I bought one of the early Holsun Red Dots, encloded type for my AR15. Love it, still works well. I now have a pistol with an adapter plate and need DOCTOR CUT Red Dot. Could I get another plate. NO NO NO... The Doctor cut footprint is common, cost me $21 and is titanium! The Trijicon RMR optic plate for my pistol is $60. I'm not spending a fortune on red dots adapter optic plates. I would love a 407 or 507 but NO.... I went with a Vortex Venom. Holosun lost my business. ARE YOU LISTENING HOLOSUN... They make 3 or more sight foot prints but not one of the most popular? DUMB.

[@MW-bi1pi]

The RMR and Aimpoint footprints are the industry standard. The Doctor footprint is the oddball.

You are comparing a micro red dot to a full size red dot. There is no comparison since they don’t go o the same size guns. Also they are even the same model number lol.

[@freedomgorilla1]

Hey thanks for the view. Yup one is micro and one is full-size, people wonder about the sizes and ask us so sizes are mentioned in the video. But with a mounting adapter you could install the 507k or 507c onto whatever you want. I could put either onto my Glock 17 or p365. We just wanted to provide some additional info based on what people email us asking. So this is a breakdown of the differences so people can decide what they want.

[@jayv9286]

507K, nobody needs a solar panel on their red dot. Maybe one on your roof or in your backyard.

[@A1CLGroup]

I ordered the red dot thinking I was getting the green. Oh well, I’ll be okay

[@StylesBlender]

Do these have the same footprint?

[@freedomgorilla1]

Hey no they don't. The "C" models are an RMR footprint. the "K" models are a modified RMSc footprint. C's are for compact and fullsize and the K is for a sub/micro compact. The K's are probably 20% smaller in size.

[@StylesBlender]

@@freedomgorilla1 so than i would go with the C for my glock 19mos?

[@freedomgorilla1]

​@@StylesBlender well you are actually in a position where you can use either. You will need an adapter plate no matter what. But if you get an RMR adapter plate you would be able to mount the "C" if you got an RMSc adapter plate you could mount the "K" you would just have to make sure the plate will work with the holosun K series. I just got a PSA dagger which is a glock 19 clone .. and it comes with the RMR cut. I am going to put a "K" series on it because it's lower profile. The "C" will stick out slightly wider than your slide. The "K" is the same width. So it's up to you. The "C" will give you a bigger window size and the solar with auto brightness, so it's personal preference based on how you want to build the gun. Like i said for me, I want the sleeker profile so I am going to use the K on the dagger.

[@freedomgorilla1]

@@StylesBlender I also want to mention that holosun came out with the SCS MOS which is made specifically for the glock MOS so no adapter plate is needed and it's low profile to use the iron sights.

[@StylesBlender]

@@freedomgorilla1 thank you so much for the explanation. I originally wanted to mount the scs with no plate. I recently installed idot suppressor height sights on my 19 which covers up way to much of the window on the scs so now im looking at other options. Upon my research im finding that the holosun 407k is a little more durable than the 507k and dosent have the res dot flickering issue. I have time, just doing research and weighting out my options. I believe im going to go with the CHPWS plate along with the 407k…. Unless i decide to change my sights again, than i will go back to the SCS.
