This cartridge was introduced in the United States in 1908 with the Browning-designed, Colt manufactured, 25 Vest Pocket Ammunition pistol. It was introduced in Europe a few years earlier in the F.N Baby Browning, which is practically identical to the Colt. The design of these two pistols has been copied by manufacturers all over the world. The .25 Automatic has fairly high velocity for such a small cartridge. However, the energy it delivers at any range is quite low. This, combined with the full metal jacketed bullet, adds up to a very poor stopping or killing power on anything. The .25 Auto is not powerful enough for hunting anything but pests, nor is it adequate for serious self defense. However, the .25 auto caliber pistols are popular because of their small size and low cost.
