It going J frame, I’d suggest one that is .38 +P compatible. Normally .38 for most target shooting, +P for occasional practice and carry.
Speer Makes a 135 gr. +P .38 specifically designed for short barrels. I like carrying them in my Ruger SP101 named "Bubba."
Bubba only barks 5 times, But let there be no mistake. Bubba bites... Bubba bites hard.
