None screwed up by buying the 158 LSWCHP. That is still the number 1 load for defense even if it's old hat technology. Point is the 158 lead semi-wadcutter hollowpoint is still king of the hill as far as real world street track records go for stopping attackers.
Sources are the recent police/tactical journals, magazines, and other periodicals.
Documented self defense shootings show this to be true.
Buffalo Bore,Remington, Federal, and Winchester makes of this round are all excellent picks.
Remingtons' lead is a bit softer than the other brands excepting Buffalo Bore's product) and expands or deforms more easily.
These loads all work well out of even 2 inch barreled snub revolvers. There's no metal jacket to have to peel back retarding the expansion.
The first guy ever shot with the 158 LSWCHP weighed 300 lbs. and dropped instantly when he was hit square in the body with it.
Since the +P load is still the yardstick by which .38 Special rounds are judged why go with anything else unless circumstances dictate otherwise?
The only other round that equals, but does not surpass the 158gr. LSWCHP, is the Speer 135gr. JHP in +P guise.
Since the Speer load has less mass,recoil,and perceived muzzle flip there is good reason to go with that for use in snubs or full sized revolvers.
Everything else takes a very close 2nd place finish. That is in in +P guise.
