When you get a 155 to ~1300 fps, you're right up there in 6 inch barrel, .357 magnum power levels. And the .357 has been proven on the street for over 75 years.
Meanwhile the venerable .45 ACP is moseying along at around 800 fps.

p.s. for reference, I note my box of Hornady .40 S&W, 175 gr Flexlock, Critical Defense is rated at 1025 fps, presumably sufficient in velocity to fully expand that bullet and achieve good penetration ratings. Velocity was not meant to be a measure of masculinity. What's up with the push for maximum speed?

I don't care if you pay attention to the article or not. Just something to read and thin about . Credentials?? So many guys with credentials over time how shows to be not worth the papper written on so take it for what it is and shoot what you want. Right?

Energy increases directly as the weight of the bullet increases. But by the square of the velocity. IMHO, 180 is even too heavy for the 10MM.

I load 165gr, the last load I did was with accurate # 7, it was rock and roll with my FN .40 plus if I don't want to pack a 1911, the .40 I think is just as good.

If you read actual "on the street" research, there's virtually no difference in effectiveness between .38 special, 9MM .40 and .45.

No handgun, regardless of caliber or ammo is actually a "man stopper."

It is true that one's energy is better spent on actual handgun training than on splitting hairs between calibers.

Speaking of personal security, it is all too common to hear it discussed upside down. Everyone wants that magic bullet, eh, caliber. Or the such-and such pistol "just like our Special Forces". In real life, the firearm is but a backup plan. Personal protection begins with personal behavior. But that's a topic for another day.

"Too heavy" by what standard?

No, sorry...I can't act on "read it on the internet", unless there is some measure of credibility/accountability.

Do not load lead if it is for a Glock with the factory barrel. They need jacketed.

There is also a thing called momentum. It is harder to stop a heavier bullet. Also 1300 fps is a +P even for a 135 grain in a 4" barrel. 155@1300 is 10mm territory. The interim load for the FBI while they were doing their testing was the 9mm 147 grain. Bullet design has come a long way since those tests but laws of physics have not changed.
A 405 grain 45-70 will out penetrate a 308 150 grain twice as fast.
