... To make your decision on defensive round. And where do you invest most? Velocity and energy? Bullet weight/size? Or is it driven by other facts, like concealability and comfort? Or capacity in relation to concealability? Are you a bigger is better type? An accuracy is godliness hugger? What drives your decision making in what you carry and/our use at home? For me it's all about the concealability to comfort ratio. A gun is neither my primary nor most effective defensive tool, it's an incase sh!t happens backup. My mind being first and body second. So I carry simply what's most convenient, concealable and comfortable to. I could care less about ballistics other than making sure I have a reliably expanding Hollowpoint. Size matters little to none because all can and will kill and I shoot what I have well or don't have it.
