Bersa is the brainchild of three Italian immigrant mechanical engineers, Benso Bonadimani, Ercole Montini and Savino Caselli. The company introduced its first handgun to the market in 1960 and quickly became a well-respected name in the firearm world. Over the years, Bersa’s Thunder models have became one of their most famous pistols. We carry Thunder BB gun replicas in our online store. Check them out below!
