So,being fairly new to the knowledge on guns, I'd like my first question to be on hollow point bullets for a 9mm Beretta. On one end, I'm told these bullets are great for on person defense and that their impact can be deadly as their known for mushrooming out. On the other end, I'm told the 115 grain cartridges are deadlier. I could use some input. Which one is better for defense? Wouldn't they be about the same depending on range and aim?
