What type of hold do you usually use? Some people are used to a bullseye hold where they'll place the bull on top of the sights or cut the bull in half with the top of the front sight blade. Most Sigs are "combat sighted", for which you align the top of the front and rear sights but hold the front dot over the bull. If you are holding the dot over the bull, then you may need to swap the front sight out, as Sig has suggested.
