I think Magtec will work fine I use in my interarms, Their some cheap hot spanish you can get off inter net . Santa Barbra or something like that. For a SD carry being older I would use Corbon Powerball its hot and is a hp with a ball in nose to make sure feeds in pistols that have trouble with regular HP This stuff over 1200fps and 240ftlbs and thats from a PPK size pistol.
