Most likely some here can recommend a suitable J frame grip. I'm out of date on the subject but suggest looking at Hogue offerings as one source. Our valued member @Lost River sells 38 Short and 38 Long ammo based on shorter cases from the past. This ammo might be a suitable alternative to the regular .38 Spl round. If you purchase another J frame, consider getting an all steel model and not an air weight aluminum version. The extra heft will slightly reduce felt recoil.
