About the Handgun:
Also referred to as the Model 50, the Megastar is a large, all-steel, double-action(DA/SA), double-column semi-auto pistol whose platform design can support toolings for both the .45 ACP and 10mm Auto cartridges. The design uses internal slide rails, instead of more usual external rails. The safety lever has three positions: up for "fire" mode, where the red dot is shown; middle for "safe" mode, this withdraws and locks the firing pin; and down for safe decocking, after which the safety lever springs back to the "safe" position.
About the Manufacturer:
Founded by Julián and Bonifacio Echeverria, this company manufactured small arms in the Basque region of Spain from about 1905 until 1997. The the Star trade name was formally registered in 1919, and all subsequent weapons were marked as such. Star filed for bankruptcy protection in late 1993 after several attempts to survive a financial downturn that began in 1990, and eventually closed its doors on May 27, 1997.
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.
