I own the XD 9mm Subcompact, XD 9mm Service and a Ruger P95. I am very accurate with both the Ruger and Subcompact but am struggling with the Service. I have had the Service about 3 weeks and have put about 400 rounds through it. I am getting better but the other two guns seem much more accurate than my service which does not make sense to me. I do believe that much could be my fault but, because I am much better with the other two, it makes me wonder if the sites may be off with the Service. I will say that I have had both the Ruger and Subcompact for about 6 to 8 months. Maybe I am just more comfortable with these guns and have not gained the confidence with the Service. I would think that if I was accurate with the Ruger and Subcompact, I would not be having this much trouble with the Service. Any ideas. Again, I am shooting a few inches left and low with the service. Don't have that issue with the other two guns.
