Sent in EPS #392, got replaced with #8428.
Installed it no problem.
Looking forward to shooting it.
I forgot to post these. Here is the Calculated Kinetics MOS plate for my EPS.
Very well made plate. Very tight fit with dry-fitting the optic to the plate.
You will need a long shank torx bit if you use a wrench like the Wheeler fat wrench.
Looks excellent. Sits very low overall even though it's a plate system. No rounds through it yet due to a complete lack of time. This is not a work gun and is a backup to my EDC G19.5 MOS with ACRO P1. I will hopefully have some range time on it soon.
I'm a little annoyed with their website. I bought a set of Ameriglo GL-453 because per their description;
"GL-453 1L Tall Black serrated .220" Front, Flat Black .295" Rear. Good for a lower 1/5 co-witness on a Glock MOS and our DOGTAG for the EPS/EPS Carry."
It is not a lower 1/5. They are unusable. I will try switching out for some classic GL-429 sights and see how they work out.
Had the exact same experience recently. Like the plate, it's solid so far and I have about 400rds on it. But I ordered the next size up in sights (GL-455 as described on their page) based on their description of lower 1/3 cowitness. As you said with yours, my sights were a good bit lower than the description, probably less than 1/5 even though they are taller than your 453's. And borderline unusable.
The upside: I contacted them, they are super cool about it and willing to work with you to swap out sights or whatever. Haven't decided yet whether to replace the 455's. Trying to see with more rounds downrange, if I can adapt to having such low, blacked-out BUIS. If I do switch, I'll probably go back to something taller and a front night sight, like the GL-511's I have on another G19 MOS with a 507C.
Definitely contact them. They have excellent customer service.
I received their EPS plate for my M&P after not being totally satisfied with my C&H plates. The Calculated Kinetics plate is much thicker and raises the optic keeping the irons from cluttering the optic window. Where the C&H plates allow the mounting screws to pass through the optic and plate into the slide, the CK plate has hardware that attaches the plate to the slide and then separate hardware that attaches the optic to the plate. Ordinarily I would see the added hardware as a negative but the robustness of the plate and its neat fit to the optic and slide are so good that I'll deem it acceptable.
I did have an issue with the forward protrusion of the CK plate preventing my gun locking into my Safariland ALS holsters. I contacted CK via Instagram and they responded immediately. CK advised they planned on resizing their future plates to accommodate ALS holsters. I was impressed with their customer service as well as their plate.
