The Beretta PX4 .45ACP SD was designed and built off of the proven PX4 Storm series of handguns for the U.S military and their JCP or Joint Combat Pistol trial to replace the M9 9mm service handgun. With the requirements put down from SOCOM as their drawing board, the PX4 SD meets and exceeds these to bring you the best possible fighting handgun. Dark earth frame, extreme weather resistance, extended barrel for threading for suppressor use. Tactical case and 3 magazines standard, along with being chambered in the venerable .45ACP. The PX4 SD is great for left handed shooters, with reversible magazine release and ambi slide stop along with ambi decocker/safety lever. The barrel on the PX4 storm rotates instead of tilts like traditional semi auto handguns. This results in more rearward recoil and less muzzle flip which means faster shots on target. With all these features packed in, along with the legendary realiability from a manufacturer as old as Beretta. The PX4-SD .45ACP is ready to defend your home or your community.
