Holosun Optic and cowitness irons

[mscampbell2734]

Does anyone run either a Holosun SCS or EPS?

It's my understanding both have very low deck height and high suppressor height sights block a good deal of the sight picture.

I'm asking because I have a 5 in CORE pistol with high sights and I'm considering the EPS or SCS.

Thanks

I have an M&P 10 mm 4 inch with a
Holosun 507 circle dot site and I absolutely love it. I don't notice the Iron sites at all.

I also do not notice my "iron" sights unless I need to look at them for some odd reason . Your focus should be on your target or threat using a dot optic and once your at least as good with a dot optic as you might have ben with open sights for defensive needs under 15 yards you might not even notice your stock sights . I do run a gold bead on my 1911 but m&p's or blacked out sights , no white dots wanted and NO large glowing bright front sight with a dot optic for me .

If your focus is on the target, as it should be, the dot should just 'appear' in your vision. You won't see the sights or the glass at all, especially under stress. A good training tool for this is masking tape over the front of the optic, which will force both eyes open and a threat focus.

I tried an EPS carry, and it had an unacceptable level of parallax for me. 3-4" variance in POI at 10 yards if I moved my head around with the dot still visible in the window. My 507Ks, 507 and 508 Holosuns do not have this problem. You can move your head slightly and there is no parallax, no dot movement.

I prefer the full size sights on a full size gun like the M&P. Mine have 507s and 508s.

I think a lot of the previous replies don't really understand your question.

Yes, the suppressor height sights on your CORE will block a significant portion of the optic window with those two optics. While target focus is important, blocking that much of an already small window is far from an ideal setup.

The only exception to this is that since the EPS uses a mounting plate, depending on how thick the mounting plate is, you could gain enough height for the suppressor sights to be in an acceptable position. I'm not familiar with the EPS mount options available right now for M&Ps because I had mine direct milled with the standard height sights.

If you're set on an EPS or SCS (I have two EPS Carry, 1 EPS, and 3 SCS) I'd recommend you go to standard-height sights. Personally I'd look at different optics, particularly if this is going to be a duty gun.

Looks like some of us don't see the tall stock sights while other have issues with them . Might be an experience level problem ?! Anyone new to dot optics one be better to start off with your dot optic on a 22lr pistol . Weigand base that adapts to some non railed pistols . Then also lest your open sight skills by practicing Flash Sight Picture shooting style . With time you;ll find the shift to a dot optic can be more of a natural change .

If your defensive limited or lack of sight focus is good you might be surprised how how well you can run your normal defensive drill shooting with No Sights at all .

Are you running an EPS or SCS with the tall sights?

FWIW, I've had an RMR, and currently have 2 507Cs, and a 509 ACSS on M&P 2.0 full size and compact variations.

With the 507Cs and RMR on factory steel plates, and a C&H plate, the factory tall irons seem like a good height for backup sights. With the 509 on a C&H plate (only game in town for the 509 ACSS on an M&P), they're barely visible.

I looked through a buddy's M&P with an SCS MP2 a while ago, and I remember the tall sights taking up around half of the window. I remember thinking that I'd switch it to the regular height sights if it were my pistol. The owner was planning to do just that.

This would be less of a factor with a full size EPS due to sitting on a plate along with the larger window, but to what degree, I can't say, because my EPS Carry is on a Shield Plus, and my EPS full size is on a Stribog. On the Stribog, the rear deck height difference between it and the RMR is enough to allow the flip up backup sights to be usable if necessary.

Old holoson 407C-gr x2 bought back in 2020 I think . No interest in in the newer enclosed units on a handgun yet as ours older holoson's still work well . I use a rubber cover on my dot optic that is attached to my belt with a small branded cord . When holster is drawn from my normal 3:00 carry position the cover is pulled / pealed off . Dream Plastics is the one I use . I have no issues with what I have used for about 3 years and have around 8000 rounds fired using this dot optic . But I did say I still rely on my stock open sights for my full size 40sw daily carry even while wearing trifocal eye glasses . My practice future CC handgun is a m&p compact 4" with the same 407c0gr x2 on it s my wifes m&p core .

Just be darn sure your very good running your draw and fire drills with a dot optic before mounting on your daily carry. No one looks worse at the range than some one hunting for the red or green dot optic .

I honestly can't tell if anyone answered your question, OP. Yes, the EPS has a very low deck height and SCS even more so. The CORE suppressor height sights will block about half of the window.

However, assuming you haven't bought a plate for the EPS, you can look at the Calculated Kinetics plate which, counter intuitively, is thicker to raise the EPS for a lower third co-witness so the factory tall sights obstruct less of the window.

I personally prefer to mount the red dot as low as possible and replace the iron sights. The SCS can co-witness with factory low sights but the EPS, with an thin adapter plate, needs sights somewhere between the factory low and tall sights.

Thanks.

I like the looks of that system, with the shield to block carbon spray from the LCI. I also like the idea of raising the EPS so it's on a similar level of other optics. Even very small variations in optic height can affect how quickly one can pick up the dot.

In my case, the SCS doesn't block out much of my Irons because I'm using a "Law Enforcement Only" M&P with low night sights. This makes for a nice combination. I keep the sights on because sometimes in shooting matches you might need to shoot weak hand only and acquiring the front sight helps indexing through a relatively small window if you're not well trained in it.
