Sig Romeo Zero red dot question

Not sure if this question fits in a gunsmithing forum, but hopefully someone can help me out.

I put a new Sig Romeo Zero red dot optic on my P365XL, when activated the red dot is in the upper left hand corner of the display.

My question is this: where does the red dot go in relation to the front sight? On top? Covering it up?

71 year old trying to learn something new, thanks for your patience.

When you zero your optic you may find the red dot position is higher than your front sight. When shooting you will be concentrating on the red dot not the front sight.

I have the original romeo. The slide it lives on came with suppressor sights Not the night sight kind and yes the dot sits slightly above the front sight on mine as well. I am still undecided about the red dot sights though aging eyes may decide that for me. Will see what the eye doc says about my cataracts which are sort of inching up on needing to be done.

I went to one of those Sig days at my range. I shot a SAO P226 and 229 with a Romeo dot.

The guy from Sig recommended I ignore the factory (Suppressor Height) sights and just concentrate on the optic.

And, I assume that after mounting the optic on your gun, you'd need to bore sight it and fine tune everything to hit at point of aim at a given distance.

Here are the instructions I got straight from Sig for the Romeo Zero.

With the Romeo Zero, a special zeroing procedure needs to be followed, or else the optic can become irrevocably damaged.

I would strongly recommend following the following procedure:

After installing the Romeo Zero using an applicable in/lb torque wrench, do not attempt to boresight, "co-witness",

or zero the optic without discharging the firearm in any fashion.

Take said in/lb torque wrench with you to the range. Set your target at a distance of minimum 12.5yds.

The Romeo Zero is specifically designed to zero at this distance, any attempts at zeroing closer will very likely result in disappointment.

After acquiring a shot grouping, clear the weapon and prepare to adjust the optic by relieving torque on the two mounting screws.

When the optic is appropriately torqued down on the slide, one or both adjustment screws may freeze.

Make your adjustments carefully and very slowly. After adjusting, torque the optic again to ~9 or ~10 in/lb.

Follow the previous steps until you are zeroed.

Failure to follow this procedure can permanently damage the adjustment screws and housing, which will necessitate service.

Sounds like another reason to avoid Romeo zero. I like the one I have didn’t try to collocate as generally sight for 25 yards anyway.
