Holosun EPS/ EPS carry on p320

Hello everyone. I been looking at the holosun eps and eps carry coming out. Apparently they use the K footprint. I was then looking at C&H precision web site and the p320 507k/407k spacer plate. From what I could tell from the pictures it appears that the K footprint uses the Romeo 1 pro screw holes. If that’s correct then those spacer with the new EPS and EPS carry would be an awesome combination. The Carry has the built in rear site for the p320 models where the rear sight is removed for installation and the regular EPS for the ones where it remains. I understand they are low enough to work with standard sites. I hope I’m not late to the party on this but I think it’s going to be really good.

I love the idea but I am hoping they come out with that model with the multi reticle...that would make it perfect...

I have a holosun with the ACSS Vulcan reticule. I love it.

I really hope they come out with an EPS with it.

I have the 507c with the ACSS also and really like it, I run it on my x5 leigon . I just picked the C&H adapter plate for the K footprint to give this a try once the EPS/EPS carry are available.

Not the only one, I used the chpw plate to mount a 407c to my legion. Already had the 407c. I was going to save up an just get the 508t. But now that I see the EPS, I think I am going to buy the other plate and mount that.

The EPS worked out great on my pro cut slide, you will love it.

Glad to hear, yeah I mean closed emitter just seems worth it, since the gun will mainly get carried owb or open. So once I figured the cost of plate and the eps red 2 moa, is about the same as a 508, just seemed like the obvious choice. Glad your liking yours just gives me that much more confidence in my choice.

I have a 508T on my p320 Zev slide build and it’s solid but I prefer the closed emitter for everything these days. Here’s a link to my post which shows my Zev build with a 508t and the pro cut slide with the EPS. As info I would prefer to add a closed emitter to the Zev but due to the Zev optic cut and recoil post I can only run an rmr style optic.

I just received my EPS Carry. I put it on my P320 with the CHPWS Adapter plate for 507K. I was running a 507K before today. The real cool thing is that the EPS Carry body and built-in rear sight actually sits lower than the 507K rear sight. You can cowitness with standard height sights on the EPS Carry whereas the 507K rear sight slightly sticks out above the standard height rear sight. I went with EPS Carry over the EPS because the Carry will be flusher with the slide of a P320.

Only thing I'm unsure of is the screws that came with the EPS Carry. They seem to screw in fine into the holes of my RXP P320 Slide but they look slightly skinnier than the screws that came with the 507K which I have been using for a year now. The thread pitch seems the same but I'm not sure if there's some difference there or how to know which screws to actually use.

you have to use the screws which come with the p320 chpw filler plate. The screws which come with the holosun optic are the wrong size.

Yeah that's what i did instead. one thing to note, since the EPS Carry sits even lower than the 507K, one of the screws is now long enough to mess with the ejection spring inside the slide. got to shorten it or get a shorter screw for one side.

I also just got a new EPS to go on my AXG Pro using a Springer precision adapter plate. The EPS really does sit quite low and should work great. Does anybody know what specs the mounting screws should have for this application? On the C&H site it looks like they list theirs as M4x11mm which I suspect should likely be the same. Does that seem correct? The screws which came with the Springer Precision plate aren't quite right as the screw head definitely doesn't sit flush with the optic deck.

I do believe they are m4x11. You may have to trim them, some people report having to. I bought some a few months ago and I bought m4x12, they are some sort of lathe or machine screw. I found them on eBay and Amazon.

Are you getting a lower co-witness with those sights? I currently have a 407c on my
p226 legion and I almost actually get a lower cowitness with my standard sights. Perhaps not perfect but atleast so the irons might still be usable.

Very nice, could we get some additional top and co-witness with the sights pictures.

YES, this please. That looks awesome, would love to play with that instead of looking at the pic. I love the way that came out Sekiro..

I finally got the EPS bolted up to my AXG Pro over the weekend. The adapter plate is Springer Precision, but the included screws weren't quite the right fit for the EPS mounting holes. Luckily I was able to find some perfect screws from Tyler at Calculated Kinetics:

Wood Bullet Kitchen utensil Metal Machine

It doesn't quite cowitness with the stock XRay sights though, but I'll have to get it out to the range again this upcoming weekend to test some more.

Holosun is good about providing additional screws if you need any in the future, my EPS Carry included screws were too long for my P365 like everybody else, emailed them, had a pack of several pairs each of various lengths within a week.

I'm using the CHPWS plate and it barely co-witnesses with the sig sights that came with the slide:

I was looking at the included screws of the EPS Carry and it turns out it did include screws that work with the RXP Slides. I missed them when I unboxed the optic because I assumed they were all the same thickness. They have multiple sets of skinnier screws that can go in P365 slides and a single set slightly thicker screws that work with P320 RXP slides. the only issue is that one of them is too long, so you have to file one down just a bit. I took it out last week and it worked out great.
