The PT1911's would have a smaller or slimmer grip and some day Taurus may actually release it for sale in 9mm. But, until that happens your choices are .45acp or .38Super. You could also go with thinner grips, depending on how much too big the grip is for you. Finally, the PT809 might be just right as it is not only a thinner grip but also has interchangeable back straps to fit different size hands. I have the PT845 which is the .45acp version and it is a very comfortable gun to shoot.
