Quoted:
Since it moves so slow compared to 9mm..Does .45acp ammo need to be +p to get the penetration I want for a Self defense barrier pentration( light cover) windshields, ect.round.. Saw a thread where the .45 ammo did not penetrate aluminum 3/8" thick target but 9mm ball did. 9mm will always out penetrate .45 through hard barriers, but that has nothing to do with terminal ballistics. You do not need +p in .45 to shoot through barriers like auto glass. In barriers where BOTH .45 and 9mm penetrate, the .45 deflets less than 9mm. If you REALLY want to shoot through harder barriers, then go with .357 sig. |

No way. Very few (if any) benefits of +P ammo in .45ACP.

If the .45 needed +p pressures to be effective, it would have never attained the reputation for effectiveness that it now has.
That reputation was built on standard pressure ammunition. Neither pressure or penetration correlate well to cartridge effectiveness. |

I thought the 115 and 124 had more penetration than 147 grain though? The 230 grain I have on hand is Ranger +P which i guess wont hurt in helping the big .45 penetrate, or no? |

Sorry––missed that: No. Lighter bullets, by and large, move faster and penetrate *less* than heavier bullets in a given caliber. For the 115 or 124 over 147 in 9mm, ignore the "by and large," as that is simple fact in 9mm. |

It depends on barrel length.
For a 5" barrel, it isn't necessary. Might be for a shorter barrel. |

You are correct on pressure––––but flat wrong on penetration. If a round fails to reliably penetrate far enough to disrupt the vital structures in the thoracic cavity then it is of very little use. If, on the other hand, it does, then it can be effective.
I was referring to the other end of penetration. A bullet that penetrates deeper is not necessarily the better performer. Adequate penetration is necessary, of course. So I will admit to being a tad bit short sighted in my statement, but not to being flat wrong. |

Well, technically, I'm limited to 180 grain Gold Dots in my issue .40, or 115 Silvertips in 9mm........but I pretty much ignore the authorized list, especially considering that the listed options other than Silvertips for the 9 are "9mm 180 grain Gold Dots," and some 90 grain Zero brand practice ammo If someone can find me some 180 grain 9mms, or some 90 grain bullets that work, I'll gladly try them out.

SPD/BPD has had very good luck with the 180gr GDHP they are issued, at least, I think it's 180. I could be wrong, it might be 165. I know Caddo uses Ranger T and it does well for them also. Most OIS's I have discussed with officers result in death of the suspect if a solid hit is achieved. Defiant action ceases immediately most of the time. |
