The Beretta M9A1 evolved from the base design of the battle-tested and proven M9 pistol, with input from military and law enforcement agencies around the world. Developed to meet the demanding requirements of the U. S. Marine Corps, the M9A1 incorporates the established reliability and performance of the M9, with added features needed for the ever-changing missions of peacekeeping forces. Like the 92FS, the M9A1 features a white 3-dot sight pattern for quick acquisition of the target. The front and backstraps of the frame are checkered to ensure a firm grip in both wet or dry shooting conditions.
