The Argentine military settled on the COlt 1911 pistol as their standard sidearm for their police and military. They bought Colt tooling and licensed to manufacture a certain number of Colts in Argentina. These are the "Sistema" Colts. Argentine military decided they wanted more guns but didn't want to pay Colt for more licensing, so they went to an automotive parts company called HAFDASA to ask their designers to make a new gun that would use Colt magazines and barrels to keep spare parts simple. They married the Colt design with a Spanish Star and came up with a 1911-looking pistol with a pivoting trigger like a Star, which was orginally the Ballester-Rigaud, later Ballester-Molina, named after the designers and engineers.
Handles like a 1911, but even the grips are different to avoid patent infringement.
The Sistemas and Ballesters are long gone.
