The problem is theres so many older .38's of dubious quality and strength.
I think whats needed is more ".357 lite" loads, loaded to replicate 9x19 performance and powder charge. Ie 125gr @ 1100fps from a J frame, 1200-1250fps from a 4."
This would provide more ballistic performance then .38+p, but a less recoil and much less blast then a proper .357. And there'd be no safety concerns, as any .357 revolver could easily handle it.
.38 +p 125gr = 850fps J frame; 950fps 4" (too little)
".357 lite" 125gr = 1100fps J frame, 1200fps 4" (goldilocks)
.357 Magnum 125gr =1200fps J frame, 1425fps 4" (too much)
The difference between the Remington Golden Saber .357 'lite', vs the classic full power .357 Remington SJHP shows the .357 lite concept well:
