Sighting question

[ZombieApocolypse]

I just got my 40 cal back from S&W the other day. I was having some sight problems that they claim to have fixed. Anyway, i took it out shooting the other day and it was constantly shooting maybe 4 inches to the left at 25 ft. I'm a right handed shooter. I'm trying to find out if theres anything i could have been doing to pull the gun left? I've never had this problem in the past so it kinda makes me mad since they just sent it back. Today im going again and bringing a buddy, so i'll be able to see if its doing it for someone else also.
