My wife got a new Sig P238 for Christmas. She promptly went to Beech Grove and ran 150 rounds through the gun. She found the gun shooting very lwo (at 7 1/2 yards it was about 6" low) Yesturday she took lessons from Aron Bright and he confirmed the gun is shooting low. Is there any way to adjust the sights? It doesn't seem right that a brand new gun's sights are off this much! Any suggestions?
