I’d always thought of the circle as akin to training wheels, but I thought I recalled @GJM saying at some point in the last year of so that he liked the 32MOA circle on the EPS, or maybe it was on another Holosun. Anyway, today I thought I’d try just the 32MOA green circle and compare to the 6MOA red dot. On Bill Drills (7 yds) and The Test (10 yds) my results were modestly but decidedly and consistently better with the green circle.

I figured things would fall apart at 25 yards (quick but untimed). But comparing the results of several targets for each, they didn’t. Again, modestly but decidedly and consistently better with the green circle. Weird, surprising, and a bit counterintuitive, but a data point.

In the last month, I posted this picture of a three round group shot with my rattler at 50 yards using a Holosun 507 in circle only mode.

I don't see any difference in my groups with a circle versus a dot. I do find a dot easier to shot call with. The circle works great in low sun angles because it is not subject to splatter like a single small two moa dot.

On the 507K, which my wife runs in circle only mode on her 365 EDC, the circle eats batteries quite a bit faster than a single dot.

The circle def eats batteries faster

I have come to prefer for anything other than slowly shooting at 25 yards or more:

Circle and dot
Circle
Dot (6 moa)
Dot (2 moa)

Carry with circle and dot

Whenever an eps carry or 507k had started acting up for me (can't adjust brightness usually) it has always been battery almost deleted and a new one has fixed it

Hey GJM, where is the thread with your posts where you were running a EPS on your P365, I can't find it. Are you still running the EPS on your P365 ?

Still running it and it works great, although it is larger than the EPS Carry.

I run an eps carry with circle dot for edc. I replace batteries every quarter

How does the carry work with suppressor height sights?

Thinking of putting one on my staccato p with the rmr adapter plate but wondering if the sights will be in the way of the window.

When comparing direct-mount, the EPS window will obviously be lower and the sights will look taller. In your case of mounting on an RMR plate, here're the relevant dimensions:

RMR deck height is ~0.34"
EPS deck height is 0.25"
EPS to RMR adapter plate is 0.1"
EPS Carry to top of back up sights is ~0.300"

Basically, EPS deck height, with adapter plate, mounted onto an RMR cut will be within 0.01" of the RMR deck height. Relatively speaking, your sights will appear to be the same height above the deck of the optic.

ETA: I hope somebody checks my measurements just in case!

The sights are roughly lower 1/4. I need to zero both the EPS and the BUIS. Hopefully next week. We'll see how I like the BUIS'. They sit low in the window, yet still give me a good sight picture. The bottom 1/3rd of the rear notch is obstructed by the seal/ant of the rear lens of the EPS, but it still provides for a good sight picture.

For those interested, the EPS/DPP adapter put the rear deck of the EPS about 0.125" above the slide top. https://uploads.tapatalk-cdn.com/202...e473fbfabf.jpg

Thanks for the informative post/pic. Anyone have this set up with the CHPWS plate instead of the DPP? I have a G19.5 MOS with a CHPWS (GL-EPS) adapter and the Holosun EPS. Trying to find sights similar to what your picture showed. Unsure of plate thickness differences between the CHPWS and DPP.
