Hammerli AP20 Air Pistol

The Hammerli AP20 is an accessible PCP air pistol developed specifically for precision shooting on the range. Made by Carl Walther, this model is aimed at beginner sport shooters and shooting clubs looking for an affordable entry-level model with the characteristics of a true match pistol. A notable feature is the interchangeable SPEKTRAL barrel sleeve, which comes supplied in six different colours for a personal touch.

Our Experience with the Hammerli AP20

The Shogun team found this pistol to be exceptionally light and well-balanced. The finish feels refined and the controls are intuitive, even for those who are new to range shooting. The adjustable grip and the position of the air pressure cylinder in particular stood out positively during aiming and firing. The shot behaviour is calm and consistent — exactly what you need for precision work at 10 metres.

Technology, Performance and Specifications

The Hammerli AP20 operates on PCP (pre-charged pneumatic) with a maximum fill pressure of 200 bar (2900 PSI). This model is chambered in caliber 4.5mm (.177) and delivers a maximum of 7.5 joules, more than sufficient for accurate shooting at a fixed distance. The total length is 41.5 cm with a barrel length of 250 mm and a sight radius of 365–375 mm. Weighing just 870 grams, the pistol remains comfortable to hold, even during longer shooting sessions. The single-action trigger provides a smooth, predictable release.

Use and Operation

The ALL-IN-ONE grip is adjustable in sizes S, M and L and is suitable for both left-handed and right-handed shooters. Without an adapter, it functions as a universal grip. The PRO-LINE air pressure cylinder can be positioned both horizontally and vertically, allowing you to determine the balance of the pistol yourself. A safety catch and a clearly readable manometer make it safe and straightforward to use. The included carry case also contains a fill valve and the necessary tools to adjust everything to your preference.

Who Is This Air Pistol Intended For?

The Hammerli AP20 is ideally suited for beginner range shooters, youth shooters and shooting clubs looking for a reliable match pistol without immediately stepping into the top segment. The extensive adjustment options also make the pistol appealing to more advanced shooters who want a lightweight training firearm for precision exercises at 10 metres.
