Odds are, if it has the HS stock with the fat palm swell, it's a 700P.
Like most have mentioned... a 700 is a 700 is a 700. If you like the parked finish, and the price is good, buy it!!!
FYI, the new XCR's are NICE!!!!!! The new triggers may very well be the BEST factory triggers I have ever pulled, and are completely adjustable down to about a pound and a half. Also, the Bell & Carlson stocks are way nicer than the HS ones. The XCR Compact is my next build up base.
