I'm looking for information about the introduction of the Remington .38 Special +P 158gr lead hollowpoint load, currently known as RTP38S12A, but which was known for decades as R38S12. I am not considering using it now; my interest is in satisfying my curiosity about its early history. I have searched the internet and numerous publications from the 1970s, and the earliest reference to the load I could find is from a 1979 Remington catalog. But I've seen comments from folks in a few places suggesting it was available prior to 1979. I have found sources indicating Winchester's version (X38SPD) was available around 1970, that Federal introduced its version (38G) around 1977, and that maybe S&W had its own version, as well, during the mid-late 1970s. If anyone can provide any specific info on when the Remington version was introduced to the LE market and to the non-LEO market, and on any specific departments using it during the 1970s, that would be very helpful. I've written to Remington seeking the info, but wanted to tap into the knowledge base here also.
