A new 9mm round for the FBI that matches the ballistics of a 45

In addressing the 9mm Takeover led by the internet, Dave Spaulding says he talked to someone at the FBI:

Is it true the FBI has found a 9mm cartridge that “matches the wound ballistics of the .45”? My friend told me they are “very encouraged” by the load they are currently testing in 9mm, but all he would tell me is it is a non-traditional bullet weight and configuration traveling at a non-traditional velocity in order to achieve this performance.

Interesting. Though they’re not the far off in terms of ballistics in the way people try to measure that stuff.

Of course, Dave also said in the linked piece: over half of what is printed on the internet is complete and utter bullshit.

So, maybe it’s some of the R.I.P. ammo I’ve been reading about?

    That would be hilarious.

    Sounds like some Ammo that PMC made back in the day.

    If they have a lovely technology breakthrough that can upgrade the 9mm to .45 effectiveness levels, imagine what it would do to the .40! Then we’ll all have another bandwagon to watch.

    It could also be some ammo from Liberty Ammunition. Earlier this year, I shot some of their USM4 series 9mm and .45. It was lightweight, high-velocity ammo. I don’t see it on their website anymore, but they do have a new line called Civil Defense, which pushes a 50-grain 9mm at 2,000 fps.

    The goal is long, wide wound channel with maximum transfer of kinetic energy. Sorry, I don’t see the RIP bullet being any better at that than say, a Hornady XTP.

    My late mother, raised in AR, would have said, “you can’t make a silk purse out of a sow’s ear”. That pretty much sums up the 9mm Luger round. It’s fine for small pistols to carry concealed, with multiple hits, its adequate as a stopper.

    As a “one-shot stop” caliber, 9mm is borderline, no matter how fast you drive the bullet. A 45 ACP has almost 50% more efficacy, or energy + surface area, the best indicator of wounding potential.

    Go to and run the numbers of your favorite defense loads in the computer formula there. Physics don’t lie, 9mm is not superior to 45 ACP for stopping people.

    If they made a .45 version it would probably be regulated by the NRC…

    No pistol round is really a man stopper so whats the difference. If you want to put someone down first time every time, then a rifle is the order of the day…

  8. Paul Kisling Says:

    Aerodawg hits it on the head. Pistols are indeed weapons of last resort. Of course carrying and Ak or a Mas 49/56 would attract asshole law enforcement even more than open carried pistols.

    Police get their panties in a wad when their is a situation they cannot micromanage.

    For some reason PDB’s blog doesn’t seem reachable by me. It looks like DNS is blocking it.

  10. Mike V. Says:

    Its not what you hit them with but where. I carry a .40 because that’s what my agency mandates. If I could go back to a personally owned weapon, it would almost certainly by a 9mm with +p or +p+ ammo. Less recoil impulse and larger ammo capacity would both be a plus.

  11. Paul Says:

    So are they talking about the World War ONE .45 ballistics? Or what?

    See the .45 has advanced to.

    Now I pack a 9mm quite often but I don’t consider it a .45. Fancy ammo can help but then fancy .45 ammo can help even more.

    So don’t get to excited about this gee-wiz stuff. Wasn’t to long ago the 10mm was all in the rage among the FBI.

    Confirm DocMerlin here: I’m using OpenDNS and it’s bouncing — even as it asks “Did you mean” and that links bounces the same.

    Might just be a brief domain name lapse. It happens.
