I have jackets older than you are so you are not old.. I carry both semi and revolvers but for the most part the 642.. I also carry with standard pressure rounds. I do however carry a high capacity semi if I'm traveling somewhere where the possibility that I might need it is greater. For everyday carry I carry one of the j frames for weight and because I'm 67 and grew up with a K frame 4" 38. How do you like the ruger revolvers by the way?? Thanks
