Help needed XD .40 Goes from Accurate to Inaccurate

[scooter123]

Any sudden change in the point of impact relative to aim would lead me to suspect that either the front or rear sight has shifted. I would check to see if the sights are well centered in the slide. "Solid" to finger pressure means nothing, how solid are the sights when tapped with a hammer and punch? If you can move either sight with a light tap, they need to be removed, have locktite applied, and be re-installed perfectly on center.

It's the shooter, not the gun. Fix your grip, trigger pull and follow through on each shot.
