This Colt prototype by engineer Robert Roy explored a gas-operated self-ejecting revolver mechanism. While innovative, it faced practical limitations, only ejecting 5 of 6 rounds and requiring cylinder opening for reloading anyway. The design featured a unique gas tap and vent system, but remained a 'tool room' experiment with mismatched parts.
The Colt Model 1971 was an internal prototype developed in the early 1970s to modernize the service pistol, aiming to improve upon the M1911. Key design goals included enhanced maintenance with stainless steel, increased capacity via double-stack magazines, and improved safety with a DA/SA trigger. While it evolved into the Colt SSP for the M9 trials, it ultimately lost to the Beretta 92.
