I use 130 gr ball ammo from any major mfg. for practice.
I carry Hornady low recoil .38 Special because my wife hits well with it in her M-38. If she has to use my M-638 we're good.

Who notes any of the current SD ammo from major mfgs are good, the nitpickers are pole-vaulting over mouse turds discussing differences.
