Okay guys, I'm carrying 9mm Speer Gold Dot 124 grain +P hollow point. Should be equal or better one shot stops compared to a .45 ACP round, no matter what Colonel Cooper may say otherwise. Rather have 13 rounds of stopping power that fits in my pocket. Those old tests proving .45 stopping power were done using cows. Don't see many cows in the city - prefer gelatin tests and modern science. Regards, Keys
