I’m 71 and carry a 340PD, or a Taurus .380 in retirement and neither would be much good in a situation like the FL school shooting w/o being very close to the shooter. That said my choice would be a Glock 17 w/two spare mags. Difficult to hide but I have to find a way.

After LEO retirement I taught in a four year college criminal justice program, first and second year students, and I carried my J frame against school rules. It could get me fired but not arrested so I didn’t care. It was pocket carried in a holster so no one knew, and I’d do it again.
