38 S&W vs. 38 Special
In addition to Guy's post. The 38 S&W compared to the 38 Special has a history of over 140 years of production behind it. A one liner doesn't quite cut it.
Both were actually originally Black Powder rounds. The 38 S&W introduced in 1876 having a standard load of 15 grains FFFG black powder behind a 147 grain round nose bullet.
The 38 Special introduced in 1899 had a standard load of 19-21 grains of FFFG Black powder load behind a 158 grain round nose bullet.
The performance comparison in penetration?
The 38 S&W penetrated 4 1/2" of pine boards
The 38 Special penetrated 5" of pine boards.
So, I honestly don't see where anemic comes into play.
The biggest advantage of the 38 Special over the 38 S&W is case volume which translates to versatility.
Even much later into the Smokeless ERA? The M&P 38 S&W (NOT special) was manufactured in very large numbers during WWII... Over 560,000 were manufactured by Smith & Wesson for the British. Using their "man-stopper" 38/200 round.
If I personally owned one of those Modern swing out cylinder WWII Military revolvers? I would not hesitate to hand load rounds that exceeded 1200 fps "safely". So, Black Power or Smokeless? The original 38 S&W was far from anemic.
