I sent a Ruger Super Blackhawk to a Gun Smith (sent it with my son he lives close) . My son gave it back to me today and it is not right at all . I ask the Gunsmith to install a Free Spin Pawl in this Ruger a Power Custom Part . Now the problem the hammer dose not cock and hold most of the time . If I cock the hammer fast and hard it will set some of the time . I hear a hard metal sound when I do try to cock it and the hammer is not holding good set on the trigger . Also if it does set the trigger pull is very lite . Question Is the Free Spin Pawl just not fit well or other problems ??
