Congradulations! How many do you have? My mother in law has been hinting and wanting grandkids but we're just not there yet. Unless the good Lord has different plans we're going to wait for a couple more years.
If the pain is lacking so is the discipline...

The Ruger is a great revolver & choice. I would recommend (as always) to have a Wolff spring kit installed. It'll still be reliable but the double action trigger pull will be 40% less felt pull weight. It'll be especially important if you have the hammer spur removed to make it DAO.
