Why should I buy expensive ammo for daily carry?

@John292

chances are you won’t be expending any of your carry ammo other than a small sampling for a function check, or periodic refreshing of your supply, say once a year or so—YMMV.
Cost then, becomes much less of an issue.

Very true - also if you unload and reload the ammo from a magazine repeatedly you’ll want to check it each time you load and shoot it off more frequently.
