Bowen Classic Arms has extra-long firing pin replacements for Super-Redhawk DA revolvers and they run $15.95. Order it and if you need it installed do it yourself or have a local gunsmith install it. Or watch a You-tube instructional video and see how it is done. Bowen Classic Arms has instructional notes on the two styles that Ruger has used so you can get the one that works for your gun. Bowen Classic Arms are excellent in what they make. Both as to their custom revolvers and their excellent parts. I hope you will look at their website and see what you can find out.
