FMJ, anything you want, as for a SD load Ranger SXT is also a great choice. Though it is no longer made I really like Taurus 45 ACP, it used Hodgen powder and the copper Barnes bullet and was also made for a short barrel.
Good, especially in the winter were heavier clothes are used...but watch them, because they to have a tendency to set back in the case when chambered a fees times. And in a 45 that's not good
