Hello, this is a used HK P30SK factory 3.27 length 9mm barrel and recoil spring guide rod assembly. Not for any other make, model, length, or caliber. Exterior finish is not in mint or perfect shape as it has some marks & scratches, and finish fading/bluing loss. Bore and rifling both look pretty good overall. Please see pics for more details. Any questions, feel free to ask. I do my part to get the item to you quickly but I do not, obviously, control the speed at which the carrier delivers it. So if your item is late, please have some patience, thank you.
