Any gun is better than no gun.
Would suggest a Taurus or Smith hammerless (or shrouded hammer) “snubbie” in 38+P. Lotta good loads for them. I know it doesn’t begin with a “4” but it will work, if you do.
My favorite range gun is a S&W 686 w/ 4-1/4 barrel.
Too big for carry, but it did teach me to love wheel guns.
An air weight snub nose .357 would also be a good carry gun.
Absolute reliability!
