I think a lot of folks begin their handgun quest with .40s - not sure why but they do. Sigma .40s and Taurus .40s seem to be the first pistol of choice for many folks. After spending time with the .40s, many folks realize 9mm is cheaper to shoot and less snappy so they unload the .40s. I have a pair of .40s myself, both Sigs, and they shoot well. Never cared for .40 much in the lightweight poly guns...
