If the Colt "Ace" functioned
correctly, to the Military eyes, it had the obvious disadvantage to not satisfactorily
simulate the powerful recoil of the .45 model. During the 1930-31's, David William, an
independent designer, created a new system called "floating chamber". The firm
Colt bought the rights and began the production in August 1935, under the commercial
reference of "Service Model Ace". Some 13,800 pieces were produced until 1945.
Production resumed from 1977 to 1982, with a reappearance in the 1997 catalog, to fit with
the striker safety components. More information are available in our book.
