ive been looking around for the new p250 comp with tact barrel but i cant seem to locate one in stock online and none of the local shops seem to know what im talking about. does anyone know if this is just a modification with a barrel from a different sig like a 220. last i check the 220 is the only other compact sig makes and it does not come with a tact barrel...so how anyone is fitting a 5 inch barrel in a compact beats me.
