I'll tell you something a .38 Specail AND a .357 Magnum can't do...become as good as a.44 Special.
Why subject yourself to excessive recoil of +P and .357 Mag when you can get a .44 Special that is comfortable to shoot and more efffective? I remember when the popular thing to do was to take a Model 28 S&W and have it converted to .44 Special.
