The subject pretty much says it all. At what range should I zero my 9mm XDM 5.25. Everything I've found pretty much says 25 yards for 9mm. I'm having an issue with my gun (which has been back at SA for over 2 weeks) and they are trying to tell me that the gun shooting low at 25 yards is normal. I disagree because with the same ammo, I do not have to raise my point of aim when shooting my 9mm Shield or Glock 19 and these guns obviously have shorter, non-match grade barrels and a shorter sight radius. The ballistics charts I've looked at all show 9mm starting to drop around 28 yards with 115 gr FMJ rounds, regardless of make. Thoughts?
