shoots low

Has anyone else had this issue? Right out of the box my Legion is shooting about 6-8 inches low at 10 yards. I expected much better for the price

Hey everyone, I am relatively new to this site and Sig as well. I recently acquired a p220 carry sao .45 acp. The gun shoots really low (6" @ 12 yds) It has no trauma signs (dropped, etc) and is almost new condition. The previous owner said he bought it new, and has fired less than 150 rounds...
