It looks like the barrel is not rotationally aligned in the receiver. Note the lack of symmetry at the extractor cut.
Note how the left side of the cut is vertically aligned, and the right side of the cut has a step.
Does the barrel witness mark line up, and is the front sight perfectly vertical to the receiver and frame?
