I am currently trying to decide which model m1917 to save up for and buy. The S&W m1917 came around when the U.S joined WW1. The government realized that they would not be able to produce enough 1911 for the war effort. So they turned to the two top civilian revolver makers: S&W and Colt. Some of the requirements were that the guns had to be in 45 acp and that they had to have 5.5 inch barrels. S&W and colt simply modified existing models to meet these requirements. The S&W version of the m1917 is a very sturdy and well liked gun. Over 150,000 were made by S&W for WW1. In 1937 the Brazilian government ordered 25,000 of these weapons to use for their military and police. Another order was placed around 1946. On the market today the Brazilian gun is cheaper than the original WW1 gun. Please voice your opinion because I need help deciding which to get!
