At one time GA Arms had 50 round baggies of those 32 S&WL JHPs at gun shows around here at an attractive price… these days if you don't reload, you'll probably have to take whatever you can find. I doubt you will have any significant performance gains using JHPs in this rather mild caliber, but they won't hurt anything.
My preference for hand loading is a lead SWC, but they don't show up in factory loads very often.
