Please clarifiy your question. ALL XDs come with a grip safety which is found on the back strap as well as a trigger safety. Only a handful come with a Thumb safety and NONE of those include ANY sub compact model. The thumb safety was added for LEOs that required them and they are available to the public. The only model's I'm aware of them being on are the 4" service models, most in 45, but I could be mistaken.
