To get my SR9 to shoot close to accurate, I had to move the rear sight so much to the right, the edge is slightly over the edge of the slide. Anyone else had this issue. All types of ammo are the same. Customer support to sent me a return label.
Loosen the screw with a 5/64 allen wrench, tap it with a non metallic object, mine didn't take much force at all. Mine shoots 3-4 inches left. It's consistent, I just felt like I shouldn't have to move the sight as much as I did to get it right.
