Colt was also in the .32-20 business and offered at least six models in that caliber. I have both an Army Model (1910) an an Official Police Model (1932) in .32-20. It was also the most popular chambering in the Colt Bisley Model. The 32-20 SAA and Bisley models pre-dated the S&W Model of 1899 in .32-20 by about 10 years.
