The SFP9 rectilinear percussion pistol is a modern single action trigger weapon in caliber 9 mm x 19. The characteristics of the weapon are unique and innovative. The patented loading rods at the rear of the breech make cocking easier. The disassembly process takes place without tools and requires a specific sequence to provide maximum protection against accidents. The weapon cannot be disassembled without first removing the magazine. Unlike other comparable weapons, the SFP9 disarms automatically upon disassembly. In addition, it is not necessary to pull the trigger before disassembly. The ergonomics and the charger of the P30 are included in this new family of weapons. Not only does the SFP9 use the charger of the P30, but it uses the backs and interchangeable grips which allow 27 different combinations. The quality of its departure allows maximum precision in rapid fire. It is based on the combination of an ideal grip, a reduced starting weight and a short relaxation and rearming stroke.
