Also known as: HW 75, HW75 SSP
Overview
The Weihrauch HW75 is a single-stroke pneumatic, single-shot target air pistol chambered in .177 (4.5mm). Manufactured in Germany by Hermann Weihrauch, it uses an overlever pumping system that charges a measured volume of air with a single stroke, delivering completely recoilless operation prized for match and plinking accuracy. It features a two-stage adjustable match trigger, an ambidextrous checkered sport grip with thumbrest, rifled barrel, adjustable rear sight, and an 11mm dovetail for optics.

Notes
Single-stroke pneumatic powerplant means each shot requires one pump of the overlever; it is not a CO2 or pre-charged design. Velocity figures vary with pellet weight; lighter pellets reach roughly 410 fps (125 m/s).
Background
Weihrauch built its reputation on spring-piston rifles, but the HW75 carried the company into the recoilless single-stroke pneumatic target-pistol niche, valued by club shooters as an affordable trainer for Olympic-style 10-metre air pistol disciplines.
