Compared to the last Colt pistol contracted by the military, the 1911A1, the new M45 is vastly different. But in some respects, the M45 more closely resembles the first 1911 issued prior to World War I. The M45, however, is by no means your great-granddaddy’ At first glance, the M45 looks like a Colt Rail Gun, except it has a desert tan Cerakote finish instead of being all-black. The M45 starts out like all Colt 1911s, from chunks of stainless steel forged into a receiver, slide, slide stop and barrel. Non-stainless models are forged from carbon steel. The forging process actually makes the steel stronger and allows tolerances to be more closely held. It also makes the receiver tough. The .45 ACP round has an average a chamber pressure of 21,000 pounds per square inch (psi), but the Colt receiver can easily stand high chamber pressures like those from .38 Super and 10mm cartridges, which have average pressures of 36,500 and 37,500 psi respectively. Not all 1911s in the market are manufactured from forgings—Colt builds theirs to last. The framework of the Colt is designed for strength. Having a forged slide stop is extremely important because it is the one piece that holds the slide, barrel and receiver together."
