Between 1942 and 1945, Ithaca Gun Company made 382,000 of the .45-caliber Model 1911-A1 pistols for our military. During that time Ithaca received a Certificate of Appreciation from the federal government for the improved manufacturing procedure for the triggers. Ithaca Gun Company announces the release of the new venerable Model 1911. Manufactured 100% right here in the USA at our factory in Upper Sandusky, OH. Weve applied the same quality principals that go into our shotguns to this outstanding firearm. Starting with the frame and slide that are hand lapped to exacting fit for the owner that demands a precision firearm.
