An expanded +p 9mm hollow point bullet will approximate .45 ACP ball and have about the same penetration. Expansion is an if. Recently bullet technology makes expansion less iffy. It's a trade off, with a little loss of ballistic impact for a smaller weapon, but close. The military is confined to ball nine mm, so it's experience doesn't compute in a civilian analysis. The average shooter going to put more nine mm hollow points into a target in the same amount of time and then some because of the extra magzine capacity. At least some of those are going to expand. Trust me. The perp will think he's been shot by a .45 ACP even though you know different. NYPD undercover cops killed Sean Bell with two or three 9mm hollow point rounds to the head. One detective got off about 31 rounds by firing two magazines. A passenger in Bell's car was hit eleven times and survived. If it had been .45 hollow points, would the passenger have died on account of the increase in caliber? That's a real fine line. It's more about where the bullet goes than what it does. That's my take on this issue as just another message board expert, of which there are no end of. Happy New Year.
