Most serious professionals will say that the 9mm Lugar (9x19) is the minimum round worthy of trust. I don't think very many will argue that you should go lower than the 9mm, but a few die hards will suggest that the 45acp is the ONLY round worthy of trust. Clearly many LEOs have settled on the 40s&w. Its somewhere between the 9mm and the 45acp, leaning pretty close to the 45acp in energy figures.
I carry either a 9mm or a 45. I don't feel undergunned or underpowered with the 9mm.
I gave up on the 380acp (9mm Kurtz) long ago. Recently sold my 380, doubt if I carried it more than 10 times in the several years I owned it. The diameter may be equal to the 9mm but the weight and the velocity combined yield very inconsistent results in expansion, especially when shot through heavy clothing. There have been advancements in 380 ammo, but at the same time the 9mm has also gotten better.
Feel secure with your 9mm and the Glock 19 is a good tool to carry. You are not underpowered, it is enough.
Every other friday night is freak night, is that wrong?The .380 is fine if you are shooting at naked people. How often do you get to do that?
they have safety rounds . . . . .have the knockdown power of a 45 . . . . . they are expensive about a dollar a round .
Well while on a technical basis I agree with you, on a more colloquial level the term "knockdown power" is often substituted for the more correct term "energy" which is a measurable factor based on velocity and weight.And "knockdown power" is a myth. Handgun rounds, even most rifle rounds, can't/won't knockdown a human. The physics doesn't support it.
