Yesterday, I bought a S&W Schofield clone that is in immaculate condition for a song. Here's the problem: the cylinder does not turn when the barrel is pointed level or upward! When the gun is pointed downward it functions fine! There is some sort of bar in front of the hammer that I can visually see engaging or not engaging during hammer cocking. What gives? I think it's the so-called "lawyer friendly" internal safety malfunctioning, but obviously I am not a gunsmith. Opinions?
