Umarex HPP Co2 Pistol Blowback 4,5mm (Max 10 joule, licens free)

Heavy pistol with several nice features at a low price. The blow back mechanism generates recoil when the casing flies backwards at the moment of the shot.

The robust all-metal construction has a removable magazine for 15 rounds and a frame with mounting rail. The removable back strap allows for quick cartridge changes.

Other notable features include the soft trigger and easy-to-use safety. With a firing capacity of up to 150 rounds from a 12 g CO₂ capsule, this pistol is revolutionary.
