This CO2 Blowback pistol from Umarex features fully licensed Beretta trademarks and is a 1:1 scale replica of the real 84FS. The gun is powered by a 12g CO2 cartridge which is contained inside the 12 round magazine. The frame and slide are fully made of metal, giving the gun a very realistic look and feel. The crisp blowback action also adds to the realism of shooting this airsoft pistol. If you're looking for an affordable sidearm this is a great choice. It is compact and lightweight yet still packs a punch and is very durable.
