Clip one coil from the firing pin return spring. That should do ya' right. Some Tauri revolvers appear to have one too many coils in the firing pin return spring. It won't do no harm cuttin' a coil off as all it functions for is to return the firing pin back in the firing pin chamber after each trigger pull. I did that on my 627 6" barreled Ti-Tracker and it sovled all my light primer strike issues.
