About the Manufacturer:
'Firestorm' is the brand name of firearms owned and sold by SGS Importers International, Inc. until 2011. Revolvers and Government 1911 style pistols were manufactured in Spain by Fabrinor, S.A.L., and in the Philippines by Armscor. Bersa style models were imported from the same Argentina factory that produces the Bersa Thunder line of pistols. To make them slightly distinctive from the Bersa Thunder pistols, they were given a rounded trigger guard, a stock rubber wrap-around grip, and a smooth backstrap. Firestorm pistols were marketed only in the US, while Bersa pistols are marketed all over the world.
About the Cartridge:
This cartridge was developed by John Browning and was adopted by the United States Ordnance Department along with the Colt-Browning automatic pistol in 1911. It has also been made the official military handgun chambering by several other governments, notably Argentina, Mexico and Norway. The 45 Automatic is the most powerful military handgun cartridge in use today. This is a heavy and powerful sub-sonic round. Although its muzzle energy can exceed 400 ft-lbs, its velocity and bullet weight creates a steep trajectory curve that limits its effective range to self-defense distances.
