Trijicon customer service is very good and prompt.
Loose mounting plates are what led me to start experimenting with E6000 in the first place.
I had cleaned, torqued and loctited the CZ optics system but it still worked loose.
After mating the plate to the slide with E6000, no issues in over 60k rounds (on the plate and on the optic).
After using the 507comp on some secondary guns, I’m still sticking with the 5MOA SRO.
I strongly prefer a round window visually and there’s also a little more vertical distance with the SRO over the 507comp which I like for recoil tracking.
5MOA is a nice size for almost all of the shooting sports that I do. I don’t want an 8MOA and I don’t want something smaller than 5.
Give me a 5-6 MOA in a round window that doesn’t lose dot in recoil and I’ll take that every day.
I would take either an SRO or 507comp over the shorter DPP window.
If the 507comp ever gave us the option of a simple 5-6MOA dot, I’d consider buying more.
But for now, no plans on changing from my SROs on anything I’m using for gaming. And that’s after spending time with two 507comps.
I might consider using the 507comps on rimfire rifles though.
