First, adjust the dot so it sits right atop the front sight when the iron sights are aligned.

Then zero your dot at 10 yards while completely ignoring your iron sights.

Per Gabe Suarez:

With a 10 yard zero using most full powered ammo, [red dot] sights are good for face shots from contact distance out to 25 yards, and body shots out from that regardless of the ammunition type or bullet weight.

Agreed. I shoot Action Pistol matches and I sight my DeltaPoint equipped G34.5 to impact dead center at 25 yards for longer shots in matches. Twenty five yards allows me to fine tune my POI. That same sight adjustment will blow the center out of a 3” dot at ten yards. Suarez is right. 😉
