.40 caliber rounds have become the replacement choice for Law Enforcement due to its superior ballistic properties to the 9mm.

Muzzle energy and recoil are also more manageable in full size firearms than the .45, with a higher number of rounds available in a magazine. Usually 10 or 15.

The Smith and Wesson model M+P in .40 caliber, is a polymer pistol that has evolved into a very reliable high capacity firearm, along with others, has changed the dynamic of personal defense and law enforcement.
