The Souverain was a revolver designed by Peter West.
The Souverain was designed for the Police Pistol Combat Competition in the USA in 1960. The frame was that of a Smith and Wesson Model 686 revolver with a heavy barrel and upgraded sights. The frame was made of polished stainless steel whilst the grips were made of Pachmayr. Peter West designed another competition revolver, the Excelsior.
