This does not necessarily mean that the sights are off. You may have incorrect placement of your finger on the trigger.
That being said, I have an SR9 and absolutely love it. It was one of three guns that felt anywhere near comfortable in my hands. Nice looking gun.
True but a friend of mine put a couple rounds down the pipe with the same result then we looked at the rear sight and I could by eye it was not centered. I centered it up with a caliper to get it closer all I need now is weather warmer than the 10degs we have right now to try it out. Man I wish there was an indoor range arround here.
