I have an XD45 4-inch pistol in which I have installed the PRP drop in trigger kit. I have been considering the purchase of the Advantage Arms .22 conversion kit. However, the Advantge Arms website councils against using their conversion unit on any XD that had any aftermarket modifications like trigger jobs etc. They want only 100% factory piistols. I understand that they don't want to take responsibility if their unit is used with modified arms as there are too many possible vairiables for them to evaluate from a safety and function point of view. So here is my question: Is there anyone on this forum who has used an Advantage Arms .22 conversion on an XD45 that has a PRP trigget kit installed? If so, How did it work out? Did you experience any issues with functon or safety?
