At the range tonight, I found my newly acquired S&W Victory functioned well in single action. However, in double action it misfired about 50% of the time. The misfired primers were dimpled but not as deeply as the fired primers. When the misfires were tried in single action they fired normally.
Other than clean it, I haven't tried any fixes. I was thinking that maybe I should try and tighten the strain screw. But, I wanted ideas as to the cause of the problem.
