Overview.
As the manufacturers' product page states:
The revolvers of cal. 357 Magnum have been designed to comply requirements of demanding users from among the law enforcing corps, private security agencies and citizens who take their safety seriously. The design of cartridge cylinder mounting in tilting console and shock transition control from the console to the frame considers as much as possible maintaining the minimum limits for a long time. Cylinder rotation design takes no compromise in forcing the cylinder turn by exact spacing distance to safely adjust to the barrel leaving no reckon on inertia of the cylinder to finish its turning movement. The user obtains thus a guarantee of safe action disabled when the cartridge is off the barrel axis even if the cylinder is braked, e.g. with impurities. The combination of 357 Magnum cartridge high output and our revolver makes up a reliable arms system for any crisis situation. Drop safety and all-steel design guarantee a high level of safety when carried under any condition. The accuracy and power of the six-inch version is a challenge for hunters using short guns. 
Models.
There are seven revolver models in the ALFA Series, each one longer and heavier than the last.
All the models have a 6-round cylinder capacity, and use a powerful .357 Magnum cartridge.
