Your options are 155gr, 165gr, and 180gr. What would you choose and why? I'll be using them for both Home Defense and Conceal Carry. I live in apartments with children so over-penetration is a big issue, but i also want to make sure it penetrates deep enough to hit the Vitals if a 350lb guy comes breaking in... Now general logic would say, choose the median, but i thought i'd run it by TFL to see what those who have used them think.
