i actually lived “only one carry piece for sd.” for 25 years in a variety of strict anti-gun locales my only firearm was a steel taurus 85 snubbie loaded with 38sp ball ammo. i fitted it with pachmayr grips, two speedloaders and 150 rounds. i had no means to practice shooting drills, or to buy replacement mags, different specific ammo that would “work” in it or little bits to replace oem little bits. it unobtrusively rested, loaded and secured in a lock box, for 1-2 years at a time, untended yet fully capable. i only carried it sometimes and it directly saved me once when i was swarmed in an urban riot. a revolver’s simplicity and intuitive manual of arms are mighty attractions for a one and done handgun.
