Meet Colt's M1971 Pistol: A M1911 on Steroids (That Flopped?)
In 1971 Colt unveiled a new modern service pistol, one that the company believed was the natural successor to the venerable Colt M1911/A1. At first glance, the Model 1971 looks very similar to the 1911. However, the new pistol incorporates some major changes.
Developed by the Research and Development Department of Colt Industries’ Military Arms Division, the M1971 is a double-action, single-action semi-automatic pistol. It comes in nine-by-19-millimeter, .38 Super and .45 ACP. The former two calibers allow the use of a double-stack magazine for increased capacity, while the .45 ACP version’s capacity is nine rounds.
The pistol was designed by Robert Roy and a team at Colt between 1968 and 1970. The technical report Colt released with the pistol claims that the nine-millimeter model’s increased magazine capacity compared to the 1911 eliminates the need for troops to carry additional ammunition.
The technical report on the pistol also includes an interesting section about Colt’s Salvo Squeeze Bore concept — a multiple-projectile cartridge system that could, in theory, increase the pistol’s firepower.
