I carried a Glock 17 or 22 for 25 of 28 years as an LEO on duty depending upon the issue pistol/caliber of the moment. After I retired, I carried a Gen 3 Glock 19 24/7/365(366 on leap year). Now, with all the BLMTIFA shenanigans going on, I have gone back to carrying a Glock 34 with 4 spare mags and a Glock 48 with 15 round SHIELD magazines as a BUG.
I don't expect to get into a protracted gun battle with the forces of evil, dressed as basement dwelling angst ridden depressed teenagers and gender non-conforming pink haired commandos and over fed recreactionally protesting Karens...but I allow for the possibility of running into one or several or a mob of them who want to get chesty with an old, retired, gray haired, retired cop with a slight limp to prove how tough they are and how badly they want to get shot.
.....there's also an AR pistol in the truck because, why not?
