I do not have a SXP, but I do have an SX3 which I believe has the same receiver and such. I noted that the inside of the receiver looks roughly finished as I was expecting a nice smooth finish inside the gun. However it has never failed to perform and it is my duck gun so I don't need to look pretty. I don't know if I would recommend it over some of competitors but if it fits you well and the price is right I don't think you can wrong.
