I really understand that everyone out there wants to make the best possible choice they can about their carry choices, etc., but what it really boils down to is training. Worry more about putting those bullets where they need to be as accurately and as quickly as possible. 9mm, .357, .40, 10mm, .45acp...it's all the same. Pick a premium JHP of sufficient weight, functions 100% in your particular gun and get to the range!!
