About the same as consensus so far - -
- - With a couple of additions.
For daily routine, I wouldn't change guns, just magazines already loaded with ball or 200 gr FMJ SWC. Same Commander, same holsters, etc.
If for some reason I needed something smaller, probably would rely on surgical placement with a Browning High Power. I'd look around and try to find some of the Frontier ammo loaded with the Hornady "Air Force" bullet - - 124 gr jacketed truncated cone. Otherwise the hottest 124--125 gr. FMJ I could find.
For my .38s - -Remington used to market a 158 LSWC+P. Accurate, but little chance of expansion.
I'd probably have to let my .357s set in the safe except for hunting, though.
They usually do, anyway, but occasionally I get a wild hair and load one up with Rem 158 JHP and carry it to work. Oh, well - - -
Best,
Johnny
