    Thanks for the thorough explanation!

    Now that you refreshed my memory, I was familiar with the concept, but with red dots I was just under the impression it's the same thing (since you pretty much shoot where it points at).

    I will apply your method and report back.

    Thank you for the link, I read it all, my question is basically the first question published there -
    "
    Curious . If the POI is supposed to be the same on the irons and red-dot. If I understood correctly, shouldn't the dot and the irond then line up? In the the pic the irons line up BELOW the red dot
    "

    I must admit I still don't really get the physics of it.
    I understand that in practice, once you operate the gun, you should focus solely on the red dot (in general, the main advantage IMO is the "threat focus" advantage, meaning that you focus on the threat with the dot on them - not on the front sight anymore).
    Having said that,
    if my iron sights are properly aligned, then I'd expect that the dot will be very close to the front sight when I'm looking at it - because if the dot and the sights are both properly aligned, they should point at the exact same thing, no..?

    What am I missing here?

    Horizontally, the red dot should align with the front sight post (again, forget about the rear sight post). Vertically, it may or may not. Remember, the MRDO projects physically at a point that is higher on the gun than the front and rear sights.

    If you took a string and ran it from the rear sight to the front sight to the point of impact at a given distance, it would be lower than the string from the red dot to the same point of impact. The angle of each string would also be different, because you are referencing different points in the vertical plane.

    Isn't that backwards?
    Maybe I'm screwed up.

    Depends. Windage being in alignment is the most correct, I suppose. A picture is worth a thousand words.

    I would describe the picture below as both horizontally or windage aligned with the front sight post, but vertical or elevation alignment with the front sight post is not occurring.

    The sights and dot sit at two different heights so they physically will not be able to align vertically.

    The red dot is a projection on the glass from an emitter sitting inside the optic. Adjusting windage/elevation changes how the dot is projected. It adjusts how you view the dot so that when you're aiming, the dot is on target but the barrel is pointing in a different direction.

    And to me it's not horizontally lined up, lol.

    Guess I'm confused.

    ETA: I know you're a pilot, so have this shit down, lol...

    Here is a suggestion. If the rear/front sights can be removed, remove them and try to zero the optic. I had about the same issue when I put a RDS on my pistol, kept trying to get it absolute co-witnessed and never could. I was the offered the same advice as above, remove the pistol sights and only use the optic. Within no time I had the optic zeroed. I put the sights back on, only to realize the dot sat way high of the front sight if you lined up the rear/front sights like normal.

    Back from the range.

    The gun is great for me, when shooting using irons I'm accurate, when using red dot my groupings are excellent.

    However, I was not able to zero it properly. It will hit low. Again, when using irons I'm hitting the mark, when using dot I'm tight but low - no matter how much elevation I've added.
    I believe that the elevation mechanism got ruined because of previous tries to change it without untorquing, will contact sig and see how they go about it.

    Additionally, my assumptions were right - zeroing when it's not properly torqued, then torquing, make the sight alignment to change a bit... This is poorly designed, I believe.

    Having said that, after seeing how tight my groupings are, and how well I can hit the mark with irons, I'm really waiting for the time I get it properly zeroed.

    Since you can not adjust red dot send it back to Sig.

    Send it in.

    Sig service is pretty good.

    I cracked the glass on my Romeo and they replaced it for free.

    Update:
    After inspection, Sig sent me a new sight.
    I sent the sight about 2 weeks ago, the new sight is on the way back to me now, so all in all I think it's a fair response time and excellent customer service.
    I've been shooting the p365xl with its irons, and it's been very accurate and easy to shoot. Its concealment is so much better than the other compacts I've carried so far (FNS-9C, G48), so all in all I'm quite content with the purchase.

    Can't wait to get the sight back, get it properly installed & zeroed. Will write an update once it's done.

    Yes, I am an idiot.

    So tomorrow I'm supposed to FINALLY get my Romeo back, and today I found out that the case I stored the mounting screws at - has a hole in it, and they are no where to be found :(((((((

    Been looking online, but couldn't figure out where to find replacements. Anyone for the rescue?
