The 1911 pistol is considered by many gun collectors and veterans to be the greatest self-loading pistol ever made and the grandfather of the modern handgun, which despite its age is still used alongside modern pistols today. Designed by John Moses Browning in 1910 with patent dates going as far back as 1897, the .45 caliber pistol was adopted into the U.S. military arsenal February 14, 1911. Browning had combined traits of his former pistols and built a prototype around the recently-developed .45 ACP round. The end result was the M1911.
Browning sold the pistol to Colt, the first major company that would market the handgun. During initial testing in the military trials, the M1911 fired 1,000 rounds flawlessly, becoming the first self-loading pistol to pass with a 100% grade. After World War I, the military modified the M1911 design to optimize it for combat, adding a slightly larger ejection port, shortening the trigger, extending the grip safety tang to help prevent "slide bite", and adding an arched mainspring housing to allow the gun to better fit in the user's hand. The new firearm was called the Colt M1911A1. Many companies manufactured the M1911 for the U.S. military besides Colt, including Remington and Springfield Armory. The M1911A1's power and reliability kept it in circulation through the Korean and Vietnam Wars before the pistol began showing its age. However, it should be noted that at the time that the military began looking for a new sidearm, no new M1911's had been purchased since 1945 (note; this statement only applies to large contract orders, many small special purpose purchases have been made for 1911 pattern pistols since). In the 1980's, the U.S. Military held new military trials, during which they tested numerous pistols, the finalists being the SIG-Sauer P226 and the Beretta 92F. Due to the high price of the SIG-Sauer's magazines, the Beretta 92F was chosen to replace the M1911A1, a highly controversial decision to this day.
A M1911 pistol is seen in the hands of a civilian during the final shootout.
In Death Sentence, Nick Hume decides on an Colt M1991A1 pistol as his main sidearm after purchasing it from Bones. Another M1991A1 can also be seen in the hands of the gang member known as Tommy who fires it multiple times at Nick in the parking garage. Most likely the same prop being reused.
