Features UMAREX CO2 H-P-P GUN

Umarex HPP Blowback Full Metal CO2 Gun 4.5 mm

The Umarex HPP CO2 4.5 mm is a semi-automatic air pistol designed for those seeking a combination of full metal construction, a blowback system, and good performance for recreational shooting . Its metal frame provides a solid feel in the hand, while the slide action adds realism with each shot.

It operates using a 12-gram CO2 cartridge and uses 4.5 mm (.177) caliber steel BBs. Its magazine holds 15 BBs and it achieves a muzzle velocity of up to 130 m/s .

Full metal construction for greater realism

One of the main selling points of the Umarex HPP pistol is its metal construction. Both the frame and the slide are made of metal, providing a weight and a more robust feel than models constructed primarily from polymer.

Weighing approximately 815 grams , the HPP conveys a solid and balanced feel during handling.

Blowback system with movable slide

The Umarex HPP incorporates a Blowback system , so the slide makes a movement during each shot.

This operation provides a more dynamic and realistic shooting experience, making it a particularly interesting option for enthusiasts who value the sensations of a CO2 pistol with a moving slide.

Semi-automatic operation

Its semi-automatic mechanism allows successive shots to be made by pulling the trigger, without the need to manually perform a new loading cycle between each shot.

The combination of semi-automatic operation and blowback gives the HPP a particularly entertaining experience for recreational target shooting sessions.

Magazine for 15 4.5mm steel BBs

Speed up to 130 m/s

The Umarex HPP CO2 achieves an indicated initial velocity of up to 130 m/s (426 FPS) , with an energy of less than 7.5 joules.

These features are geared towards recreational shooting at targets at distances appropriate for an air pistol.

The effective velocity can vary depending on factors such as ambient temperature, the condition of the CO2 capsule, the BBs used, and the rate of fire.

Smooth steel barrel

The pistol is equipped with a smoothbore steel barrel adapted for the use of 4.5 mm caliber steel BBs.

This configuration complements the robust construction of the HPP and is specifically geared towards operation with this type of ammunition.

Ergonomic and non-slip handle

Despite its metal construction, the handle of the Umarex HPP is made of durable ABS plastic and features a surface designed to promote a firm grip.

Its ergonomics help control the pistol's 815 grams of weight and provide a comfortable grip during shooting sessions.

Fixed sights with white dots

The Umarex HPP incorporates a fixed sight system with white references , facilitating a quick and clear acquisition of the aiming elements.

This simple configuration is particularly appropriate for the recreational nature of the pistol.

Lower Picatinny Rail

At the bottom of the frame we find a Picatinny rail that expands the pistol's configuration possibilities.

This system provides a standard interface for installing devices compatible with this type of rail.

Fire safety

The Umarex HPP incorporates a firing safety that allows the mechanism to be locked when the pistol is not in use.

As with any air pistol, it should always be handled following basic safety rules and used exclusively in places suitable for shooting practice.

CO2 feeding of 12 grams

The gun operates using a standard 12-gram CO2 capsule , a system widely used in recreational air pistols.

To properly preserve the seals and the feeding system, it is recommended to remove the CO2 capsule after the shooting session and not to store the pistol for extended periods with a pressurized capsule installed.
