The .38 Special was actually developed by lengthening the .38 Long Colt Round. The bullets were not very accurate during the Spanish American War in 1898 . It’s hard to believe but the first .38 specials were loaded with black powder! Within a year that changed.
What you are looking at is the first Model M&P revolver created specifically for the .38 cartridge. Designed in 1899 and left the factory in 1900 . There is of course the famous Smith & Wesson Model 10 in .38 Special produced in 1899 seen below.
What makes the .38 Special so special? Because of it’s black powder heritage, the .38 Special is a low pressure cartridge, one of the lowest in common use today! As you probably already know the .38 Special is particularly popular among handloaders. The cartridge’s straight walls, headspacing on the rim, ready availability of previously-fired cases, and ability to be fired in .357 Magnum firearms, all contribute to this popularity.
