Well took it to the range and it was flawless all I fed it was monarch steel case and ate it like candy. I think I like it better than my xd9sc, not sure yet but its definitely a great piece. One problem though after the first two mags my trijicon sight had shifted an 1/8 inch to the right. I noticed and tapped it back, but it loosened again. How do I fix this? I bought this gun used, but it was immaculate....and I do not know who installed the sight....other than that this gun is great.
