When the .38 Special was offered to the shooting public back in 1898, smokeless powder was less than a generation old. And for a long time it was a caliber rather well thought of. Then, sometime in the 1960s, when so many other things changed, the .38 Special cartridge became something to look down upon, mock and even disrespect. Why? I guess in time all things traditional and functional become old hat and have to be tossed aside—later reevaluated and then reconsidered. But the .38 Special?
My thoughts on this came from testing the Hornady Critical Defense ammo in a .38 snubbie. It was an all-stainless S&W Model 60, a police trade-in backup gun. The recorded velocities were quite a bit under the ones listed on the box, which came as no surprise. But their tested terminal performance was interesting.
The 110-grain standard-pressure loads ran just under 1,000 fps, and the +P loads ran just over that mark. Before you snort in derision, that’s from a barrel just shy of two inches long. The standard-pressure FTX expanded and penetrated, although not to FBI satisfaction. The +P load expanded more and penetrated more. If you can handle the extra hassle of the muzzle blast, the performance bonus is worth it.
Let’s compare those to other compact carry guns—some .380s and some really short-barreled 9mms. First off, no .380 load in existence uses a bullet of 110 grains. The heaviest is 100, and you won’t find those 100-grainers leaving the muzzle over 800 fps. To break 800 fps and approach 850 in a compact .380, you have to settle for 95 grains of bullet weight.
A 9mm will match the 100-grain weight, even best it, with 115-grain bullets. However, a quick flip through my chrono logbook shows me that 115 is not a laser beam bullet out of a compact 9mm that you’d expect. Out of a three-inch barreled 9mm, 115s typically go the same speed that 110s do out of a snubbie revolver: just over 1,000 fps.
