Overview
The Hammerli 152 is a Swiss single-shot free pistol built for ISSF 50 metre precision target shooting. It uses an improved Martini-style rear-hinged falling-block action and, unlike its mechanically triggered sibling the Model 150, fires via an electronic ignition system that dramatically shortens lock time and delivers an extremely consistent release adjustable down to just a few grams. Chambered in .22 Long Rifle, it features a free-floated barrel, adjustable weights, an orthopedic adjustable grip, and match-grade adjustable sights.

Notes
The electronic system allowed trigger pull adjustment from roughly 2 to 100 grams with a lock time on the order of 0.0016 seconds. It was the electronically fired evolution of the mechanically triggered Model 150.
Background
Hammerli free pistols dominated Olympic and ISSF 50 metre pistol competition for decades, and the electronically fired Model 152 represented the pinnacle of that lineage, with a trigger so light and a lock time so short that many shooters considered it the most refined free pistol trigger ever built.
