I have a taurus .357 4" ported barrel in ti.... I love the gun, its my deep wood back upm gun, light weight, and packs plenty of punch for oregon.... it shoots high.... I have tested it and at 10 yards it consistantly shoots 4 inches high... so can a gunsmith fix this, its a rear frame notch, and front post??? not sure if its pinned or how its built didn't look yet. Anyone have any ideas?
