Triggers

Triggers: One of the noticeable differences between the 1911 and 1911A1 is the trigger. The 1911s had long triggers that where milled throughout production. Remington Rand, Singer and Colt started production of 1911A1s with the short milled trigger. All switched to the stamped trigger invented at Ithaca, after it was adopted except Singer who was no longer making pistols. Colt did not switch until into 1944. Stamped trigger assemblies where adopted by the ordnance department in August of 1942.
