Have put about 200 rounds through my new 9mm Shield. I like this pistol very much.......but, it shoots about 1-2 inches to the left and 3-4 inches low. I have deliberately "slow fired" with careful aiming, making sure I was pushing straight back on the trigger. Not as concerned about it shooting slightly to the left; I can always adjust the rear sight if necessary. But, I can't adjust the elevation on the sights. Any thoughts or suggestions?
