The Model 45 is a double-action only pistol that shoots .45 ACP caliber ammunition with a magazine capacity of 10+1. This is one of the most iconic Smith & Wesson handguns, a polymer-frame gun known for its durability, accuracy and reliability. This model was originally produced for the military and police and that is the reason why there is ‘M&P’ in its name. It’s built on the company’s Large Frame. The M&P 45 has a removable back strap to provide users with great ability of customization and accuracy and the option of a manual ambidextrous thumb safety. The barrel and slide are made of stainless steel, for extreme durability, and the slide has been reinforced with the Armornite finish. It features white-dot dovetail front sight, and steel low-profile-carry rear sight. Overall, this is a very strong, reliable handgun ideal for self-defense or home protection.
