One of the big issues with red dots, at least for me is locating the dot when pressing the gun into shooting position.

Yes I know, practice, correcting faults, etc are the way to work on this, however it continues to be problematic and reading comments, I'm not alone.

the ACSS Vulcan model has a chevron for the dot, and a circle, not a small one around the chevron, but a large circle that helps you center the firearm and find the "dot".

If you present the gun to the target and don't see the chevron (center) you will see part of a circle in the screen, which indicates the direction you need to move the firearm to align the center dot in the screen.

Pretty cool tech, of course with practice you'll learn where center is, this should help show what you're doing wrong in presentation, how to correct it (direction) and reinforce good habits once you start finding center consistently.

At least that's the theory, and at $300 it's not overpriced. Going to put it on the P320 Legion, basically because it needs an optic.

Heres a video showing it being unboxed and how the light works.

Thanks! That looks great. Reminds me of the Eotech for AR's.

looks exactly like an eotech at a practical level to me. I ran those for years shooting steel pistol matches (until we had the big lie and they offered to buy them back and I returned them). I loved the outer ring as it matched exactly a plate diameter at short ranges and was very very fast. But over the whole course of that time I don't think using the 65moa ring helped me figure out exactly where to go look for the dot. that's just silly slow. anyway enjoy and good luck.

Regarding finding the dot -

I have four pistols with red dot sights. The first one was a CZ 75 with a factory installed frame mounted OKO red dot. That was very slow (for me) in finding the dot since it was well above the slide mounted iron sights. Almost put me off red dots.

Next I got a pair of pistols (SIG P226 and FN FNX-45) with red dots that co-witnessed with the iron sights. Both came with suppressor height iron sights. By co-witnessed I mean the red dot is essentially superimposed on the white dot located on the front sight when the sights are on target.

If I can find the iron sights I can find the dot with these two. An additional benefit is if the red dot fails I have not compromised the utility of the iron sights. I strongly prefer suppressor height sights on pistols with red dots.

My forth red dot pistol is a P365 with a Romeo zero. Here the iron sights are not co-witnessed and not nearly as usable. The dot is quick to pick up, but if it fails the iron sights are only usable at close range.

I might get rid of my Romeo on my X-Carry and give this a try. I think it's a pretty neat concept and seems executed well.

I've got one and it is much better than the RMR that it replaced...

Something I’ve found that helps finding the red dot is this little trick that Walther showed Colion Noir:

They need to make a version of the 507K with this. It has the circle already. Just make it bigger.

Primary Arms knows how to make good reticles. I have one of these ACSS Vulcans, and it is outstanding. Going to get more and sell the regular 507C that I have.

I have one on my backup/match gun. The ACSS is interesting and of some value for odd positions and finding the chevron. I one thing I do not like is the auto brightness feature. It does not work near as well as an RMR. Drawing from concealed and pushing out in my bright AZ sun several times it has been to slow to respond and I have had a very dim and hard to see chevron. If you are going to make it your main EDC gun I would go with an RMR. This one is on my backup/ match gun so I am ok with it but just do not think the Holosun is as good as an RMR.

I would like to try the chevron, replaced the Romeo Zero on my 365 with the 507, and it’s a much better sight. But I’ve also been wanting a Delta Point Pro on my M18, tempted to try this instead.

I love the Holosun guns and the ACSS variant has my interest for sure. It's interesting that you have to get it from PA and cannot get it from Holosun. I found that once I cleaned up my presentation the dot finds itself in normal drawing. With that said, under or to the side of cover and odd positions make finding the reticle a real thing and I think there is merit to the idea of this reticle.

I wish they'd pop it into a 509T.

I put a Holosun on my Ruger Deerfield and I really, really like the circle and dot (like a crsip EoTech) and the controls. If and when I get a pistol with a red dot, this stands a good chance of being the optic.

Thanks for helping the CCP run Trijicon into the ground.

Ah, there it is. We all knew somebody would, eventually

If Trijicon doesn't want to be run into the ground, Trijicon (who, btw, is just a stone's throw from where I live) should try harder.

I've related the story two or three times here on SF, so I won't bore y'all with it again. Suffice it to say more than once I tried to give Trijicon my business. They made it impossible for me to do so. Holosun ended-up getting it.

There are other companies besides Holosun.

Checked them all. Even personally laid hands on many of their products in LGS'. In the end: Nobody could match Holosun for features--particularly at their price point.

Go ahead and find me something that can beat the Holosun HS510C at even twice the price. I don't know if anything exists today, but it didn't 2-3 years ago.

And before you go down the "reliability" road: People have frozen those things in ice, dragged them down trails behind 4-wheelers, repeatedly cast them into the middle of ponds with casting rods, thrown them 12-15 feet in the air and let them hit the ground, shot them with shotguns, run them atop rifles known to be hostile to optics, and more. They kept working and maintained zero.

I didn't want to buy Holosun. Or any optic made in China--regardless of whose name is on it. The other manufacturers left me with no choice.

Since you mentioned Trijicon, specifically...

Back when I was looking for a rifle optic I tried to buy Trijicon. Real hard. Despite the fact the Trijicon MRO cost more than half again what the Holosun HS510C cost, had far fewer features, and tweaked my astigmatism worse than the Holosun product, I still tried to go with it. After all: Not just American-made, but a Michigan company, to boot. I was willing sacrifice all those things if only they'd offer a circle-dot reticle. So I reached out to them, asking them if they were considering doing so.

They blew me off.

A couple years later they finally came out with a circle-dot reticle--at nearly twice the price of the dot-only reticle model, making it three times as expensive as the HS510C. And still it has less features.

Trijicon can bite me

I'm a big fan of Trijicon. I believe in the products of theirs that I own. But they're no more perfect than anyone else. The RMR set the standard but arguably in many ways the bar has been raised by others. The bottom load battery especially with the first gen design is a major annoyance in more than a couple of ways. The sight picture is definitely smaller and cramped than what the up and comers are providing. Trijicon's big selling point of toughness and durability got thrown out the window with the SRO. With their late-to-the-party RMRc they decided to upset the proverbial apple cart by using a different mounting pattern that most of their competition had been maneuvering into some resemblance of an industry standard. And of course there's the pricing differential, which to ANYONE on a budget is damn hard to ignore. And you can argue about the pettiness of their on/off switch patent, though to me a patent is a patent even though it seems like a stupid one that never should've been awarded in the first place.

Holosun for me is the first PRC-sourced optic company that offers something I think is thoroughly usable with excellent value. Granted that I don't have a wealth of extended use and experience with wide range of optics like others may have. But I was unimpressed with the build quality of my two Primary Arms optics that others around the web had crooned over. I absolutely hated my Vortex red dots with extreme prejudice and still can't fathom all of the love people toss at the boat anchor Razor LPVO Gen2 and its edge distortion that I sold off. My early SIG RD optics functioned okay but one didn't take abuse very well and the other's similar build standard probably will go the same way. The guys who develop the optics that Holosun builds (seems to be the same kind of business model that Vortex uses; conceived here and then built there) seem to have a reasonably good handle on what it takes to provide a solid, reliable optic. We've had no real problems with any of units, besides getting a couple of different lots of 507C X2s with the same product SKUs and UPCs (and price) but different content (one with the M1913 mount, the other without).

Two customer returns so far, but in the post-return forensics the issues seem to be more customer-created than a problem with the quality of the products themselves. There was one 407 that was DOA, something that we've also experienced with Vortex and SIG...and Leupold and Nikon (before they tucked tail and abandoned the gun business), for that matter. To their credit we've not had that with Trijicon, Aimpoint or Steiner, but we also sell a lot less volume of those product lines being that so many of our customer base is price-cognizant with their purchasing. That said, the aforementioned bottom (un)secured battery issues of the RMR were a sore point with a few of our customers. We just got some of Trijicon's latest LPVOs in and I have to say that I like 'em, but those too are offshore-sourced, made in Japan. So even Trijicon has to play the game.

I only have a lone Holosun unit, a 512C that resides on my SP5K. At this point I don't expect myself switching to anything else; this Holosun has been stellar so far but admittedly I haven't run enough of that "precious" 9mm through the gun to really formulate a firm op/ed one way or the other. But I do like the 32MOA circle on this gun and it's definitely super easy to pick up. The optic's housing seems quite robust and I can easily buy three of these for the price of the Aimpoint CompM5B that I'd been lusting after. My VP9L Tactical is in need of a red dot and given my experiences so far with the big 512C I can easily see myself buying a Holosun instead of another RMR. Like my customers I too am price-sensitive and when I can save some serious money those kinds of savings with seemingly very little practical downside is a VERY hard thing to just leave on the table.

I have an MRO and an SRO and astigmatism.
Please tell me more about the Holosun reticle being less of a mess.

Everybody's astigmatism is different, Richard. Take a group of people with astig and a handful of RDS' from different manufacturers, and odds are different individuals will experience different levels of messiness with different products. For me, for whatever reason, the Holosun HS510C tweaked my astig the least.
