ASG Bersa Thunder 9 Pro - 4.5mm BB

Since 1958, Bersa has been manufacturing accurate, reliable, and robust handguns, utilizing advanced firearms technologies paired with a history of innovation.

The Argentinean Military, as well as law enforcement officials around the world, have routinely issued and relied on Bersa handguns as their official sidearm. Bersa is currently one of the largest privately owned corporations in Argentina. 

Originally developed by Bersa, as a military/law-enforcement sidearm, the Thunder Pro HC was built to perform under adverse conditions and provide decisive stopping power. This is a semi-automatic 4.5 mm airgun version fully licensed by Bersa. It is powered by a 12g CO2 cartridge stored in the grip using the easy-load system and the BB's are put in a removable stick magazine. The Thunder Pro HC is a lightweight, full-sized handgun, with an ergonomic design. An integrated picatinny rail allows for mounting of lasers or tactical lights. The grip and slide caries authentic Bersa markings and every gun comes with unique serial number.
