Karen, I am aware of 2 shotguns factory made with a shorter stock. I believe the first is a Beretta but can't remember the model. The second is the Browning Ladies Gold Sporint Clays. Both are semi auto's. In addition to the shorter stock, it has some other modifications specifically for women. I recently purchased one and love it. However, I agree with the other responses, a gun fit is hightly recommended.
