Gary, I have the same gun in.44, and have never had any problems. The first thing that came to mind when I read your post was the possibility that the factory did not get the barrel indexed properly. Does your front sight look like it is perfectly centered vertically? Also, put some conscious thought toward your grip. Are you left handed?
If you have thought through all the possible variables, and the problem still exists, I would contact Ruger, and send it back to them. I believe that random quality control issues with all brands of firearms are getting worse.
Best of luck!
