In older days the 158gr LSWCHP +P (also known as a LHP +P in at least one company's offering) enjoyed quite a satisfactory reputation when fired from regular 4" service barrels, and even from 3" barrels (like the FBI's Model 13 RB 3").
It even enjoyed a pretty good reputation when fired from little 2" snubs, although some of the FBI-influenced ballistic testing didn't seem to produce much in the way of expansion. I have some factory testing from Winchester somewhere in my older notes, dated 2002 (I think), in which the bare gel and heavy clothing results, using a S&W Model 60 2" snub, averaged .36 caliber.
However, anecdotal reports from older times over the years seemed to indicate decent effectiveness in actual shootings involving its use in snub revolvers. Maybe because the soft swaged LHP design would hit bone and deform and/or expand? Dunno. There were some satisfied LE users of it, though. Hey, an all-lead hollowpoint probably had a better chance of deforming or expanding than one of the old-style 158gr JHP or JSP loads, even in +P. Those older thick jacketed cup & core JHP/JSP's didn't exactly produce consistent expansion when fired from 4" service barrels, so you might imagine the potential falling off when even shorter barrels were involved. At least the all-lead hollowpoints didn't have to overcome a jacket, right?
The Rem version was reputed to be softer than the Win version, and it was observed to do better in some gel testing of the time, and the Fed version seemed to fall somewhere between? I still have most of a box of the original Fed 158gr Nyclad LSWCHP +P left over in my collection of older duty and off-duty ammo, as it was one of the then-newer 158gr loads I carried in my older J's back in those days.
