Well at one time certain lots of 158 LHP would jump crimp , but undoubtedly since ultra lightweight revolvers have been so popular , the mfgs are on top of it . If 158 LHP were my choice , I'd just be sure to test the particular ammo .
Other than that minor caveat , it comes down to your prefered 2 inch ammo generally .
The variable with ultra lightweight revolvers is recoil , and how well you can control in your gun , in your hands , with your prefered grips , shooting with one hand .
And yes , the various moderate loaded .357 can have similar or less recoil than 148 +P .
Yes , in theory , .38 Spl fired in .357 chambers will have slightly less velocity than from a .38 Spl chamber , * All other dimensions being exactly the same * . But the gun to gun variations of " identical " guns is greater magnitude , so take that with a grain of salt , until you actually chronograph specific guns .
Do I feel the need for a .357 chambered J frame ? Nope . If I wished a small .357 , my personal floor would be an SP101 , which is just on the right side of being usable with full power .357 .
However , if somehow the Tooth Fairy gave me a free J Frame .357 , I would also test drive reduced .357 loads .
