In Feb of 2001, I paid $825 for a used P5C in NRA Excellent condition, 4 magazines, wooden grips and the standard plastic grips, original box and papers (manual, etc.), a Wolff replacement recoil spring, 4 Wolff replacement magazine springs, and a Ken Null horsehide IWB holster delivered. Hope that info might help a bit on the financial side.
As to opinions of the pistol itself, the P5 design is very impressive and the pistol is a joy to shoot. The workmanship and aesthetics of the pistol are simply haunting. In the end, however, I'd reach for the P225 first if looking to carry something other than my P7M8. Still, my P5C ain’t for sale.
Good luck.
