The U.S. Joint Combat Pistol Program didn’t exactly come to fruition within the military, but it did cause a number of manufacturers to produce new service-type handguns that consumers now get to enjoy. One of those is the FNX-45 from FNH USA, a polymer-frame, hammer-fired, double-action/single-action pistol based on the model FNH developed for the program.

The FNX-45 is a big pistol, measuring about 7 1/2 inches long and weighing 33 ounces unloaded. FNH focused on battlefield duty and not concealed carry when developing it. The size of the FNX-45 may rule out concealing it under clothing in most situations, but the pistol has plenty going for it as an open-carry or home-defense gun-not the least of which is a healthy magazine capacity of 15 rounds of .45 ACP.
