The PX4 Storm SD was developed to meet the demanding requirements issued by the US Special Forces Command for their Joint Combat Pistol. This pistol is the answer with .45 ACP power in one 9-round magazine and two 10-round extended magazines, FDE polymer frame, weather resistant coatings on a steel frame and internal parts. The ruggedness of this pistol is by design. It was created to work in the harshest of environments including extreme hot and cold, sandy, salty, and muddy to name a few. It boasts incredible accuracy for a tactical pistol with a 4.5 inch barrel. It can be broken down and maintained within seconds without the use of tools for field cleaning and maintenance. This pistol has a lot to offer anyone that is looking for a hard hitting tactical pistol.
