Thanks for all the advice. I will certainly look at each part and see what the issue could be. Considering the single action pull "feels" a tad bit lighter than my experience with other K-frames it could be a shortened strain screw. The thing that gets me that all soft strikes occur with .38s, and they fire on the second time around. The Magnums never fail to fire on the first hit. I suppose this could related to case length and the Magnum primer, though I am just guessing.
