Well, Mike Glover ("an operator") came out with a blazing hot take recently. Apparently people who carry JHPs are not using their whole brain and should be carrying FMJs for self defense instead for better penetration.
Not sure the justification on this, outside of maybe trying to stir up drama for more click dollars. I've always assumed the vast majority of modern JHPs like HST and anything from Hornady barrier blind enough for the average self defense scenario. It's not like you're going to have to engage someone on the other side of a cinder block wall or two in anything besides a larp fantasy. There's supposedly a part two coming with "testing", not really expecting much from it honestly as this seems pretty stupid.
Also what's with those goofy ammo choices? No sane person carries 65gr +P 9mm for self defense.
