The blue book is worthless when it comes to DW pistol packs. (as well as other firearms) I have been watching PPs for a number of years, and they can go for (up to) twice what the blue book states, or more.
It is a matter of supply and demand (as always) but I for one am not willing to supply the ($$$) they are demanding for them. Others are.
I do "hear" about one going for a reasonable price now and again, but it's always AFTER the fact.
Does it have the belt buckle?
They are nice shooters, maybe someday........
