The "P" is part of the serial number, right or wrong, generally agreed to be prototypes. Mr. Skeuse made comments on the P guns here a while back. The reason for the magnum proofs is that all 28" 20 gauge Repros had 76mm chambers. Nothing unusual about the proving of the gun, but the gun is of a very popular configuration and Chuck won't have it for long, even at that price.
