I know everyone has and will recommend hollow points, but I find it very assuring to often carry 230 Hardball in my 45s, especially during cold weather. It has been proven an effective round for almost 100years in our military. I do not care that it may not be the "most effective" round in one shot stops. Shot placement and penetration are most important, but I will add reliability equally important. Trying all different brands of HPs to prove their reliability is a task and expensive. I stock up on Federal American Eagle 230fmj which has proven 100% reliable in all my 45s. My Glock 21s feed anything, but not always the case with others. I realize that over-penetration could be an issue but getting 100% reliability gives me confidence and peace of mind. Can you make a case to carry 45 Hardball for self defense?
