    He’d unironically be better served with a .45 LC or .44 Magnum revolver.

    There is a reason no one serious on the planet uses 7.5” 5.56 guns.

    Points 2, 3, and 4 of that post are false from what I can tell. Besides tsx, what is giving you > pistol performance? The vid above shows on par or worse than pistol.

    That is not supported by the evidence, and that rnd, sure as hell didn't fail however, unless you consider 16" penetration, full expansion, and 100% weight retention, a failure...

    Again, my only real concern in this issue, is if there's added hydrostatic wounding mechanisms involved also. That's a legit aspect of the discussion.

    I don't know anything about them, but I do know SWAT teams range considerably from legit HSLD types, to little more than wanna be ninjas in cool gear. Not my lane, but I'd question the value and utility of 7.5" vs 10-12" for a LE tac team, and I do know there's various now running 7.5" in addition to who you mentioned. Their recs, wants, etc differ from mine obviously.

    ...and there's a reason that only meme tier manufacturers like PSA and Springfield offer them.

    A 7.5" 5.56 offers you zero advantages over a 10.3 and all the disadvantages.

    You're simply incorrect on that, as is anyone claiming same. I supplied the evidence, no one countered it with any convincing evidence, and no one will. Per above, I'm open to learning from anyone who can supply metrics/data/sources that counter what I said, but "just cuz" and being talked down by some, ya, no.

    I will continue to research the only relevant issue this topic as it applies to me, and that's cavitational wounding mechanisms that make rifle rnds that much superior to handguns.

    You can literally sling hot .45 with equal muzzle energy to a 7.5” AR.

    There is little to no cavitation wounding from the velocity listed, and inconsistent performance. It did not expand until 8" in. Thats my point. You're getting mediocre .224 handgun performance with a flashbang on the end. You can get the same results with a shorter, lighter, quieter 9mm.

    The ability to defeat soft body armor makes 5.56 superior to 9mm even if the terminal performance were the same.
