Design details
Designed by
Emilio Ghisoni
Emilio Ghisoni (1937 – 28 April 2008) was an Italian inventor and firearm designer, best known for his innovative work with revolvers.
Biography
Ghisoni was born in Pavia, northern Italy in 1937, and attended university to follow a course in ...
and Antonio Cudazzo, the Rhino differs from traditional revolvers in a number of ways. Stylistically it resembles Ghisoni's earlier design, the
Mateba Autorevolver

), and the receiver is CNC-machined from a solid block of high-tensile aluminium. Virtually all components are CNC-machined as well; this manufacturing process yields a very precise fit with minimal tolerances. For models other than the 20D, the trigger may be used in either single-action or double-action
